netdevice: add queue selection fallback handler for ndo_select_queue

2014-02-17T05:36:34+00:00

Add a new argument for ndo_select_queue() callback that passes a
fallback handler. This gets invoked through netdev_pick_tx();
fallback handler is currently __netdev_pick_tx() as most drivers
invoke this function within their customized implementation in
case for skbs that don't need any special handling. This fallback
handler can then be replaced on other call-sites with different
queue selection methods (e.g. in packet sockets, pktgen etc).

This also has the nice side-effect that __netdev_pick_tx() is
then only invoked from netdev_pick_tx() and export of that
function to modules can be undone.

Merge tag 'staging-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver tree changes from Greg KH:
 "Here's the big drivers/staging/ update for 3.14-rc1

  Lots and lots of cleanups, IIO driver updates are also mixed in here
  due to the subsystem still crossing staging and drivers/iio/, and the
  dwc2 driver is moved out of staging.  There's a new driver (rts5208),
  which ends up making us adding more lines than removing, but overall
  there was lots of work toward moving code out of here, which was good

  All of this has been in linux-next with no reported issues"

net: core: explicitly select a txq before doing l2 forwarding

2014-01-10T18:23:08+00:00

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
will cause several issues:

- NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
  instead of lower device which misses the necessary txq synchronization for
  lower device such as txq stopping or frozen required by dev watchdog or
  control path.
- dev_hard_start_xmit() was called with NULL txq which bypasses the net device
  watchdog.
- dev_hard_start_xmit() does not check txq everywhere which will lead a crash
  when tso is disabled for lower device.

Fix this by explicitly introducing a new param for .ndo_select_queue() for just
selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
forwarding transmission.

With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
dev_queue_xmit() to do the transmission.

In the future, it was also required for macvtap l2 forwarding support since it
provides a necessary synchronization method.

staging: bcm: clean up a type issue in ConfigureEndPointTypesThroughEEPROM()

We only ever set the highest 4 bytes of ulReg.  This would cause a
problem on big endian systems.  The type should be u32 instead of
unsigned long.

2014-01-08T23:59:27+00:00

In InterfaceRx.c, opening braces of (if-)conditionals are mostly
dislocated, meaning they are found behind an extra line break after the
conditional statement.  This patch moves the opening braces accordingly
as specified by the official conding style guidelines.
