In the original code we allocated memory conditionally and freed it in
the error handling unconditionally. It turns out that this function is
only called during initialization and "adapter->npars" and
"adapter->eswitch" are always NULL at the start of the function. I
removed those checks.
Also since I was cleaning things, I changed the error handling for
qlcnic_get_pci_info() and pulled everything in an indent level.

Currently the driver will try to protect all frames,
which leads to a lot of odd things like sending an
RTS with a zeroed RA before multicast frames, which
is clearly bogus.
In order to fix all of this, we need to take a step
back and see what we need to achieve:
* we need RTS/CTS protection if requested by
the AP for the BSS, mac80211 tells us this
* in that case, CTS-to-self should only be
enabled when mac80211 tells us
* additionally, as a hardware workaround, on
some devices we have to protect aggregated
frames with RTS
To achieve the first two items, set up the RXON
accordingly and set the protection required flag
in the transmit command when mac80211 requests
protection for the frame.
To achieve the last item, set the rate-control
RTS-requested flag for all stations that we have
aggregation sessions with, and set the protection
required flag when sending aggregated frames (on
those devices where this is required).
Since otherwise bugs can occur, do not allow the
user to override the RTS-for-aggregation setting
from sysfs any more.
Finally, also clean up the way all these flags get
set in the driver and move everything into the
device-specific functions.

Based on patches from Sonny Rao and Milton Miller...
Combined the patches to fix up clean_tx_irq and clean_rx_irq.
The PowerPC architecture does not require loads to independent bytes
to be ordered without adding an explicit barrier.
In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.
The problem occurs with packet split enabled where the TCP/IP header
and data are in different descriptors. If the reads go out of order
we may have data that doesn't match the TCP/IP header. Since we use
hardware checksumming this bad data is never verified and it makes it
all the way to the application.
This bug was found during stress testing and adding this barrier has
been shown to fix it. The bug can manifest as a data integrity issue
(bad payload data) or as a BUG in skb_pull().
This was a nasty bug to hunt down, if people agree with the fix I think
it's a candidate for stable.
Previously Submitted to e1000-devel only for ixgbe
http://marc.info/?l=e1000-devel&m=126593062701537&w=3
We've now seen this problem hit with other device drivers (e1000e mostly)
So I'm resubmitting with fixes for other Intel Device Drivers with
similar issues.

Building ixgbe without DCB_CONFIG and FCOE_CONFIG will cause
a build error. This resolves the build error by wrapping
the fcoe.up in CONFIG_IXGBE_DCB ifdefs.
Also frames were being priority VLAN tagged even without DCB
enabled. This fixes this so that 8021Q priority tags are
only added with DCB actually enabled.

This patch uses an RCU-inspired approach to fix it. In the RX tasklet's
find_vcc() function we first refuse to use a VCC which already has the
ATM_VF_READY bit cleared. And in the VCC close function, we synchronise
with the tasklet to ensure that it can't still be using the VCC before
we continue and allow the VCC to be destroyed.

I often use "ethtool -i" command to check what driver controls the
ehternet device. But because current virtio_net driver doesn't
support "ethtool -i", it becomes the following:
# ethtool -i eth3
Cannot get driver information: Operation not supported
This patch simply adds the "ethtool -i" support. The following is the
result when using the virtio_net driver with my patch applied to.
# ethtool -i eth3
driver: virtio_net
version: N/A
firmware-version: N/A

Personally, "-i" is one of the most frequently-used option, and most

RxRPC can potentially deadlock as rxrpc_resend_time_expired() wants to get
call->state_lock so that it can alter the state of an RxRPC call. However, its
caller (call_timer_fn()) has an apparent lock on the timer struct.
The problem is that rxrpc_resend_time_expired() isn't permitted to lock
call->state_lock as this could cause a deadlock against rxrpc_send_abort() as
that takes state_lock and then attempts to delete the resend timer by calling
del_timer_sync().
The deadlock can occur because del_timer_sync() will sit there forever waiting
for rxrpc_resend_time_expired() to return, but the latter may then wait for
call->state_lock, which rxrpc_send_abort() holds around del_timer_sync()...
This leads to a warning appearing in the kernel log that looks something like
the attached.
It should be sufficient to simply dispense with the locks. It doesn't matter
if we set the resend timer expired event bit and queue the event processor
whilst we're changing state to one where the resend timer is irrelevant as the
event can just be ignored by the processor thereafter.
