To ensure a proper handling of CAN frames transported in skbuffs some checks
need to be performed at receive time.As stated by Michael Olbrich and Luotao Fu BUG_ON() might be to restrictive.
This is right as we can just drop the non conform skbuff and the Kernel can
continue working.This patch replaces the BUG_ON() with a WARN_ONCE() so that the system remains
healthy but we made the problem visible (once).Signed-off-by: Oliver Hartkopp

Add NETIF_F_FCOE_MTU to indicate that the NIC can support a secondary MTU for
converged traffic of LAN and Fiber Channel over Ethernet (FCoE). The MTU for
FCoE is 2158 = 14 (FCoE header) + 24 (FC header) + 2112 (FC max payload) +
4 (FC CRC) + 4 (FCoE trailer).Signed-off-by: Yi Zou

Adds fcoe offload related net_device_ops functions vlan_dev_fcoe_ddp_setup
and vlan_dev_fcoe_ddp_done, their implementation simply calls real eth device
net_device_ops for FCoE DDP setup and done operations.Updates VLAN netdev field value for fcoe_ddp_xid from real eth device netdev.
Above changes are required for fcoe DDP offload working on a VLAN interface.

The sky2 driver combines auto speed negotiation with automatic negotiation

Transmit completion can safely run lockless against transmit start.
In the normal case, completion is done from NAPI and only looks
at elements that are at the tail of the ring. When doing shutdown
or reset, the transmiter should be completely block by NAPI disable
and blocking of transmit queue.Based on earlier work by Mike McCormack.

This unifies the places that bounce the device (suspend/resume
and restart). And makes the operations have the same semantics
as normal dev_open/dev_stop.This also avoids setting the multicast addresses twice when
device is brought up.Signed-off-by: Stephen Hemminger

The suspend and shutdown code plays with shared state. Use consistent
locking, for extra protection.Signed-off-by: Stephen Hemminger

Avoid any possible problems with accessing PHY registers on shutdown.
This is a purely theoretical issue and is not related to any of the
outstanding bug reports. Since receiver and transmitter are already
shutdown and phy interrupts for this device are already disabled,
there should already be enough protection. Suggested by Mike McCormack.Signed-off-by: Stephen Hemminger

Sometimes drivers might have a good reason to override
the PS default, like iwlwifi right now where it affects
RX performance significantly at this point. This will
allow them to override the default, if desired, in a
way that users can still change it according to their
trade-off choices, not the driver's, like would happen
if the driver just disabled PS completely then.Signed-off-by: Johannes Berg

If you trigger a scan request on an interface and then
take it down, or rmmod the module or unplug the device
the driver might "forget" to cancel the scan request.
That is a bug in the driver, but the current behaviour
is that we just hang endlessly waiting for the netdev
refcount to become 0 which it never will. To improve
robustness, check for this situation in cfg80211, warn
about it and clean up behind the driver. I don't just
clean up silently because it's likely that the driver
also has some internal state it has now leaked.Additionally, this fixes a locking bug, clearing the
scan_req pointer should be done under the rdev lock.Finally, we also need to _wait_ for the scan work and
not just abort it since it might be pending and wanting
to do a cleanup.Signed-off-by: Johannes Berg

Now that its shared we can remove ath5k's own implementation.
Signed-off-by: Luis R. Rodriguez
Signed-off-by: John W. Linville -
Turns out ath5k and ath9k can share the same helper to
allocates RX skbs. We allocate skbs aligned to the cache line
size. This requirement seems to have come from AR5210; when
this was not done it seems sometimes we'd get bogus data. I'm
also told it may have been a performance enhancement
consideration. In the end I can't be sure we can remove this
on new hardware so just keep this and start sharing it through
ath.ko.Make ath9k start using this, ath5k is next.
