The firmware spec states that the timeout for all commands should be 60 seconds.
In the past, the spec indicated that there were several classes of timeout
(short, medium, and long). The driver has these different timeout classes.
We leave the class differentiation in the driver as-is (to protect against any
future spec changes), but set the timeout for all classes to be 60 seconds.
In addition, we fix a few commands which had hard-coded numeric timeouts specified.

The reserved lKey is different for each VF.
A base lkey value is returned in QUERY_DEV_CAP at offset 0x98.
The reserved L_key value for a VF is:
VF_lkey = base_lkey + (VF_number << 8).
This VF L_key value should be returned in QUERY_FUNC_CAP
(opcode-modifier = 0) at offset 0x48.
To indicate that the lkey value at offset 0x48 is valid, the Hypervisor
sets a flag bit in dword 0x0, offset 27 in the QUERY_FUNC_CAP wrapper
function.
When the VF calls QUERY_FUNC_CAP, it should check if this flag bit is set.
If it is set, the VF should take the reserved lkey value at offset 0x48.
If the bit is not set, the VF should not use a reserved lkey
(i.e., should set its reserved lkey value to 0).

This patch attempts to fix the following problems when an actor or
partner's aggregator is not active:
1. a slave's lacp port state is marked as AD_STATE_SYNCHRONIZATION
even if it is attached to an inactive aggregator. LACP advertises
this state to the partner, making the partner think he can move
into COLLECTING_DISTRIBUTING state even though this link will not
pass traffic on the local side
2. a slave goes into COLLECTING_DISTRIBUTING state without checking
if the aggregator is actually active
3. when in COLLECTING_DISTRIBUTING state, the partner parameters may
change, e.g. the partner_oper_port_state.SYNCHRONIZATION. The
local mux machine is not reacting to the change and continue to
keep the slave and bond up
4. When bond slave leaves an inactive aggregator and joins an active
aggregator, the actor oper port state need to update to SYNC state.

If a remote machine crashes while there are pending transmit buffers, the
sunvnet driver reallocates the ring descriptors giving us enries that have
state VIO_DESC_FREE but also an allocated skb. This results in a BUG_ON()
call when the remote reboots and we reach that point in the ring.
This patch:
1) clears pending tx packets in the ring on port reset
2) changes a BUG_ON() to a pr_warn() when a remote host has given us an invalid
descriptor state
3) collapses multiple active buffer frees in a ring to a single message per
ring and adds the device name and remote MAC address
This fixes the particular problem of not cleaning up pending buffers on a
reset, but also prevents us from crashing if the remote handles descriptors
out of order or sets an unexpected state for a descriptor.

Currently we try to clear EDRRR and EDTRR and immediately continue to
free buffers. This is unsafe because:
- In general, register writes are not serialised with DMA, so we still
have to wait for DMA to complete somehow
- The R8A7790 (R-Car H2) manual states that the TX running flag cannot
be cleared by writing to EDTRR
- The same manual states that clearing the RX running flag only stops
RX DMA at the next packet boundary
I applied this patch to the driver to detect DMA writes to freed

while ethtool -G eth0 rx 128 ; ethtool -G eth0 rx 64; do echo -n .; done
and 'ping -f' toward the sh_eth port from another machine. The
warning fired several times a minute.
To fix these issues:
- Deactivate all TX descriptors rather than writing to EDTRR
- As there seems to be no way of telling when RX DMA is stopped,
perform a soft reset to ensure that both DMA enginess are stopped
- To reduce the possibility of the reset truncating a transmitted
frame, disable egress and wait a reasonable time to reach a
packet boundary before resetting
- Update statistics before resetting
(The 'reasonable time' does not allow for CS/CD in half-duplex
mode, but half-duplex no longer seems reasonable!)

While being in an ERROR_WARNING state, and receiving further

range of 97-127 inclusive, the state handling code erroneously
reverts back to ERROR_ACTIVE.
Per the CAN standard, only revert to ERROR_ACTIVE when the
error counters are less than 96.
Moreover, in certain Kvaser models, the BUS_ERROR flag is
always set along with undefined bits in the M16C status

Upon receiving a hardware event with the BUS_RESET flag set,
the driver kills all of its anchored URBs and resets all of
its transmit URB contexts.
Unfortunately it does so under the context of URB completion
handler `kvaser_usb_read_bulk_callback()', which is often
called in an atomic context.
While the device is flooded with many received error packets,
usb_kill_urb() typically sleeps/reschedules till the transfer
request of each killed URB in question completes, leading to
the sleep in atomic bug. [3]
In v2 submission of the original driver patch [1], it was
stated that the URBs kill and tx contexts reset was needed
since we don't receive any tx acknowledgments later and thus
such resources will be locked down forever. Fortunately this
is no longer needed since an earlier bugfix in this patch
series is now applied: all tx URB contexts are reset upon CAN
channel close. [2]
Moreover, a BUS_RESET is now treated _exactly_ like a BUS_OFF
event, which is the recommended handling method advised by
the device manufacturer.

net: mv643xx_eth: Use dma_map_single() to map the skb fragments
caused a nasty regression by removing the support for highmem skb
fragments. By using page_address() to get the address of a fragment's
page, we are assuming a lowmem page. However, such assumption is incorrect,
as fragments can be in highmem pages, resulting in very nasty issues.
This commit fixes this by using the skb_frag_dma_map() helper,
which takes care of mapping the skb fragment properly. Additionally,
the type of mapping is now tracked, so it can be unmapped using
dma_unmap_page or dma_unmap_single when appropriate.
This commit also fixes the error path in txq_init() to release the
resources properly.

In order to stop the RX path accessing the RX ring while it's being
stopped or resized, we clear the interrupt mask (EESIPR) and then call
free_irq() or synchronise_irq(). This is insufficient because the
interrupt handler or NAPI poller may set EESIPR again after we clear
it. Also, in sh_eth_set_ringparam() we currently don't disable NAPI
polling at all.
I could easily trigger a crash by running the loop:
while ethtool -G eth0 rx 128 && ethtool -G eth0 rx 64; do echo -n .; done
and 'ping -f' toward the sh_eth port from another machine.
To fix this:
- Add a software flag (irq_enabled) to signal whether interrupts
should be enabled
- In the interrupt handler, if the flag is clear then clear EESIPR
and return
- In the NAPI poller, if the flag is clear then don't set EESIPR
- Set the flag before enabling interrupts in sh_eth_dev_init() and
sh_eth_set_ringparam()
- Clear the flag and serialise with the interrupt and NAPI
handlers before clearing EESIPR in sh_eth_close() and
sh_eth_set_ringparam()
After this, I could run the loop for 100,000 iterations successfully.

If an skb to be transmitted is shorter than the minimum Ethernet frame
length, we currently set the DMA descriptor length to the minimum but
do not add zero-padding. This could result in leaking sensitive

In Dual EMAC, the default VLANs are used to segregate Rx packets between
the ports, so adding the same default VLAN to the switch will affect the
normal packet transfers. So returning error on addition of dual EMAC
default VLANs.
Even if EMAC 0 default port VLAN is added to EMAC 1, it will lead to
break dual EMAC port separations.

====================
pull-request: can-next 2015-21-01
this is a pull request of 4 patches for net-next/master.
Andri Yngvason contributes one patch to further consolidate the CAN
state change handling. The next patch is by kbuild test robot/Fengguang
Wu which fixes a coccinelle warning in the CAN infrastructure. The two
last patches are by me, they remove a unused variable from the flexcan
and at91_can driver.
