1. Add common code for stopping queue.
2. No need to call netif_stop_queue followed by netif_wake_queue (and
infact a netif_start_queue could have been used instead), instead
call stop_queue if required, and remove code under USE_GTS macro.
3. There is no need to check for netif_queue_stopped, as the network
core guarantees that for us (I am sure every driver could remove
that check, eg e1000 - I have tested that path a few billion times
with about a few hundred thousand qstops but the condition never
hit even once).

The e1000 driver stores the content of the PCI resources into
unsigned long's before ioremapping. This breaks on 32 bits
platforms that support 64 bits MMIO resources such as ppc 44x.
This fixes it by removing those temporary variables and passing
directly the result of pci_resource_start/len to ioremap.
The side effect is that I removed the assignments to the netdev
fields mem_start, mem_end and base_addr, which are totally useless
for PCI devices.

Add support for dual network (net_device) interface so that ethernet
and wireless can own separate ethX interfaces.
V2
- Fix the bug that bringing down and up the interface keeps rx
disabled.
- Make 'gelic_net_poll_controller()' extern , as David Woodhouse
pointed out at the previous submission.
- Fix weird usage of member names for the rx descriptor chain
V1
- Export functions which are convenient for both interfaces
- Move irq allocation/release code to driver probe/remove handlers
because interfaces share interrupts.
- Allocate skbs by using dev_alloc_skb() instead of netdev_alloc_skb()
as the interfaces share the hardware rx queue.
- Add gelic_port struct in order to abstract dual interface handling
- Change handlers for hardware queues so that they can handle dual
{source,destination} interfaces.
- Use new NAPI functions
This is a prerequisite for the new PS3 wireless support.

Code cleanup:
- Use appropriate prefixes for names instead of fixed 'gelic_net'
so that objects of the functions, variables and constants can be estimated.
- Remove definitions for IPSec offload to the gelic hardware. This
functionality is never supported on PS3.
- Group constants with enum.
- Use bitwise constants for interrupt status, instead of bit numbers to
eliminate shift operations.

<4> <0>Kernel panic - not syncing: Fatal exception in interrupt
<4>
After looking at the code and the dump I think the following scenario
happened: Ifup was running on cpu2 and the interrupt arrived on cpu0.
Now virtnet_open on cpu 2 managed to execute napi_enable and disable_cb
but did not execute rx_schedule. Meanwhile on cpu 0 skb_recv_done was
called by vring_interrupt, executed netif_rx_schedule_prep, which
succeeded and therefore called disable_cb. This triggered the BUG_ON,
as interrupts were already disabled by cpu 2.
I think the proper solution is to make the call to disable_cb depend on
the atomic update of NAPI_STATE_SCHED by using netif_rx_schedule_prep
in the same way as skb_recv_done.

This patch converts cpmac to the new Fixed PHY infrastructure, though it
doesn't fix all the problems with that driver. I didn't even bother to
test this patch to compile, because cpmac driver is broken in several ways:
1. This driver won't compile by itself because lack of its header describing
platform data;
2. It assumes that fixed PHYs should be created by the ethernet driver.
It is wrong assumption: fixed PHYs creation is platform code authority,
driver must blindly accept bus_id and phy_id platform data variables
instead.
Also, it seem that that driver doesn't have actual in-tree users, so
nothing to fix further.
The main purpose of that patch is to get rid of the following Kconfig

We must drop any packets we are not able to encrypt.
We must not send them unencrypted or with an all-zero-key (which
basically is the same as unencrypted, from a security point of view).
This might only trigger shortly after resume before mac80211 reassociated
and reconfigured the keys.
It is safe to drop these packets, as the association they belong to
is not guaranteed anymore anyway.
This is a security fix in the sense that it prevents information leakage.

This patch makes suspend/resume work with the b43legacy driver.
We must not overwrite the MAC addresses in the init function, as this
would also overwrite the MAC on resume. With an all-zero MAC the device
firmware is not able to ACK any received packets anymore.
Fix this by moving the initializion stuff that must be done on init but
not on resume to the start function.
Also zero out filter_flags to make sure we don't have some flags
from a previous instance for a tiny timeframe until mac80211 reconfigures
them.

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=9806
The TUN/TAP driver only permits one-way transitions of IFF_NO_PI or
IFF_ONE_QUEUE during the lifetime of a tap/tun interface. Note that
tun_set_iff contains
541 if (ifr->ifr_flags & IFF_NO_PI)
542 tun->flags |= TUN_NO_PI;
543
544 if (ifr->ifr_flags & IFF_ONE_QUEUE)
545 tun->flags |= TUN_ONE_QUEUE;
This is easily fixed by adding else branches which clear these bits.
Steps to reproduce:
This is easily reproduced by setting an interface persistant using tunctl then
attempting to open it as IFF_TAP or IFF_TUN, without asserting the IFF_NO_PI
flag. The ioctl() will succeed and the ifr.flags word is not modified, but the
interface remains in IFF_NO_PI mode (as it was set by tunctl).

A reset function solves three problems:
1) It allows us to renegotiate features, eg. if we want to upgrade a
guest driver without rebooting the guest.
2) It gives us a clean way of shutting down virtqueues: after a reset,
we know that the buffers won't be used by the host, and
3) It helps the guest recover from messed-up drivers.
So we remove the ->shutdown hook, and the only way we now remove
feature bits is via reset.
We leave it to the driver to do the reset before it deletes queues:
the balloon driver, for example, needs to chat to the host in its
remove function.

IPv6 or v4.
3) Rename VIRTIO_NET_F_NO_CSUM to VIRTIO_NET_F_CSUM (ie. means we do

The driver should inform the stack when checksum has been performed by
the HW when both IP and TCP (or UDP) checksum flags are indicated by HW.
Previously, it would also inform the stack when only IP checksum flag
was indicated by HW. This can cause data corruption when IP fragments
are used. The IP Identification field can wrap around and cause data
from new fragments to fill into older fragment slots with same IP Id.
The stack would then not perform TCP/UDP checksum (after re-assembly of
all fragments) since driver falsely stated it was already calculated.

I've seen reports of invalid stats in /proc/net/dev for bonding
interfaces, and found it's a pretty easy problem to reproduce. Since
the current code zeros the bonding stats when a read is requested and a
pointer to that data is returned to the caller we cannot guarantee that
the caller has completely accessed the data before a successive call to
request the stats zeroes the stats again.
This patch creates a new stack variable to keep track of the updated
stats and copies the data from that variable into the bonding stats
structure. This ensures that the value for any of the bonding stats
should not incorrectly return zero for any of the bonding statistics.
This does use more stack space and require an extra memcpy, but it seems
like a fair trade-off for consistently correct bonding statistics.

bond_set_multicast_list function. It first reduces the locking on
bond->lock to a simple read_lock, and second, adds netif_tx locking
around the bonding mc_list manipulations that occur outside of the
set_multicast_list function.
The original problem was related to IPv6 addrconf activity.

Subject: [PATCH, REPOST] Fix/Rewrite of the mipsnet driver
Content-Type: text/plain; charset=us-ascii
Hello All,
currently the mipsnet driver fails after transmitting a number of
packages because SKBs are allocated but never freed. I fixed that
and coudn't refrain from removing the most egregious warts.
- mipsnet.h folded into mipsnet.c, as it doesn't provide any
useful external interface.
- Free SKB after transmission.
- Call free_irq in mipsnet_close, to balance the request_irq in
mipsnet_open.
- Removed duplicate read of rxDataCount.
- Some identifiers are now less verbose.
- Removed dead and/or unnecessarily complex code.
- Code formatting fixes.
Tested on Qemu's mipssim emulation, with this patch it can boot a
Debian NFSroot.

Resubmitting patch from Al Viro <viro@zeniv.linux.org.uk>, with subject -
[PATCH] s2io LRO bugs.
a) initiate_new_session() sets ->tcp_ack to ntohl(...); everything
else stores and expects to find there the net-endian value.
b) check for monotonic timestamps in verify_l3_l4_lro_capable()
compares the value sitting in TCP option (right there in the skb->data,
net-endian 32bit) with the value picked from earlier packet.
Doing that without ntohl() is an interesting idea and it might even
work occasionally; unfortunately, it's quite broken.

macb devices are only found integrated on SoCs, so they can't be
hotplugged. Thus, the probe() and exit() functions can be __init and
__exit, respectively. By using platform_driver_probe() instead of
platform_driver_register(), there won't be any references to the
discarded probe() function after the driver has loaded.
This also fixes a section mismatch due to macb_probe(), defined as
__devinit, calling macb_get_hwaddr, defined as __init.

w/o the first change: if end == start you get MAX_JIFFY_OFFSET which
isn't what you want...
For the latter I think to be technically correct you need the +1 to
account for the jiffy between MAX_JIFFY_OFFSET and 0
(hmm w/ the 2nd change the first isn't strictly needed... ah well)

We must not transmit packets we're not able to encrypt.
This fixes a bug where in a tiny timeframe after machine resume
packets can get sent unencrypted and might leak information.
This also fixes three small resource leakages I spotted while fixing
the security problem. Properly deallocate the DMA slots in any DMA

The problem is that priv->assoc_id is set when assoc. resp frame is
received. But, when it is set, LQ cmd is still not sent to the uCode, it is
done from bg_post_assoc, which is called through a workqueue.
On the other hand, when a tx arrives at the moment when this flag is set,
but LQ is still not sent, the if condition in tx_skb will not hold and
the frame will not be dropped. Thus, it will be sent through
which is still not in the sta table in the uCoded.

The geo/channel information is obtained from the EEPROM, which is read
during probe. We can thus set up channel information at this time. This
helps us to support ioctl commands that rely on this before the interface
is brought up.
Clearly matches _init_channel_map with _free_channel_map and _init_geos
with _free_geos to ensure functions calling these routines can also call
their cleanup routines.
Fixes a few bugs:
- if channel information is not available when ioctl commands are
issued then we get a NULL pointer oops. Having channel information
set up during probe we can deal with ioctl commands without requiring
interface to be brought up.
This fixes bug: http://www.bughost.org/bugzilla/show_bug.cgi?id=1552
- Fix potential problem if user triggers probe/remove/probe sequence. The
value of priv->channel_count was used to determine if channel map is
set up. This value was never reset when channel map was removed.
- Fix memory leak: priv->modes need to be freed when device removed.

This zeros out all microcode related memory before loading
the microcode.
This also fixes initialization of the MAC control register.
The _only_ place where we overwrite the contents of the MAC control
register is at the beginning of b43_chip_init().
All other places must do read() -> mask/set -> write() to not
overwrite existing bits.
This also adds a longer delay for waiting for the microcode
to initialize itself. It seems that the current timeout is sufficient
on all available devices, but there's no real reason why we shouldn't
wait for up to one second. Slow embedded devices might exist.
Better safe than sorry.
While at it, fix naming of MACCTL values.

Both the old e1000 driver and the new e1000e driver can drive some
PCI-Express e1000 cards, and we should avoid ambiguity about which
driver will pick up the support for those cards when both drivers are
enabled.
This solves the problem by having the old driver support those cards if
the new driver isn't configured, but otherwise ceding support for PCI
Express versions of the e1000 chipset to the newer driver. Thus
allowing both legacy configurations where only the old driver is active
(and handles all chips it knows about) and the new configuration with
the new driver handling the more modern PCIE variants.

configure cwmin and cwmax of the beacon queue in IBSS mode according to this.
unfortunately beacon backoff does not work reliably yet, so i suspect we have a
problem somewhere else, since the same settings (and similar beacon timer
configuration) work for madwifi.

use SWBA (software beacon alert) interrupts to keep track of the next beacon
time und check if a HW merge (automatic TSF update) has happened on every
received beacon with the same BSSID.
this is necessary because the atheros hardware will silently update the local
TSF in IBSS mode, but not its beacon timers. if the TSF is ahead of the beacon
timers no beacons are sent until the timers wrap around (typically after about
1 minute).
this solution is not very nice, since we have to look into every beacon, but
there is apparently no other way to detect HW merges.

We are pleased to announce a new Gigabit Ethernet product and its
driver to the linux community. This product is the Intel(R) 82575
Gigabit Ethernet adapter family. Physical adapters will be available
to the public soon. These adapters come in 2- and 4-port versions
(copper PHY) currently. Other variants will be available later.
The 82575 chipset supports significantly different features that
warrant a new driver. The descriptor format is (just like the
ixgbe driver) different. The device can use multiple MSI-X vectors
and multiple queues for both send and receive. This allows us to
optimize some of the driver code specifically as well compared to
the e1000-supported devices.
This version of the igb driver no lnger uses fake netdevices and
incorporates napi_struct members for each ring to do the multi-
queue polling. multi-queue is enabled by default and the driver
supports NAPI mode only.
All the namespace collisions should be gone in this version too. The
register macro's have been condensed to improve readability.
