bnx2: Correctly receive full sized 802.1ad fragmes

2014-10-01T20:43:45+00:00

This driver, similar to tg3, has a check that will
cause full sized 802.1ad frames to be dropped.  The
frame will be larger then the standard mtu due to the
presense of vlan header that has not been stripped.
The driver should not drop this frame and should process
it just like it does for 802.1q.

tg3: Allow for recieve of full-size 8021AD frames

2014-10-01T20:43:45+00:00

When receiving a vlan-tagged frame that still contains
a vlan header, the length of the packet will be greater
then MTU+ETH_HLEN since it will account of the extra
vlan header.  TG3 checks this for the case for 802.1Q,
but not for 802.1ad.  As a result, full sized 802.1ad
frames get dropped by the card.

Add a check for 802.1ad protocol when receving full
sized frames.

netxen: Fix bug in Tx completion path.

2014-09-30T20:22:44+00:00

o Driver is not updating sw_consumer while processing Tx completion
  when interface is going down. Due to this interface down path gets
  stuck forever waiting for NAPI to complete.

netxen: Fix BUG "sleeping function called from invalid context"

2014-09-30T20:22:43+00:00

o __netxen_nic_down() function might sleep while holding spinlock_t(tx_clean_lock).
  Acquire this lock for only releasing TX buffers instead of taking it
  for whole down path.

net: stmmac: fix stmmac_pci_probe failed when CONFIG_HAVE_CLK is selected

2014-09-29T20:36:58+00:00

When the CONFIG_HAVE_CLK is selected for the system, the stmmac_pci_probe
will fail with dmesg:
[    2.167225] stmmaceth 0000:00:14.6: enabling device (0000 -> 0002)

This patch fix the issue by breaking the dependency to devm_clk_get()
as the CSR clock can be obtained at priv->plat->clk_csr from pci driver.

net/mlx4_core: Allow not to specify probe_vf in SRIOV IB mode

2014-09-26T20:43:23+00:00

When the HCA is configured in SRIOV IB mode (that is, at least one of
the ports is IB) and the probe_vf module param isn't specified,
mlx4_init_one() failed because of the following condition:

if (ib_ports && (num_vfs_argc > 1 || probe_vfs_argc > 1)) {
	 .....
}

The root cause for that is a mistake in the initialization of num_vfs_argc
and probe_vfs_argc. When num_vfs / probe_vf aren't given, their argument
count counterpart should be 0, fix that.

Revert "net/macb: add pinctrl consumer support"

2014-09-26T19:48:37+00:00

This reverts commit 8ef29f8aae524bd51298fb10ac6a5ce6c4c5a3d8.
The driver core already calls pinctrl_get() and claims the default
state. There is no need to replicate this in the driver.

qlcnic: Fix ordering of stats in stats buffer.

2014-09-26T19:11:31+00:00

o When TX queues are not allocated, driver does not fill TX queues stats in the buffer.
  However, it is also not advancing data pointer by TX queue stats length, which would
  misplace all successive stats data in the buffer and will result in mismatch between
  stats strings and it's values.

o Fix this by advancing data pointer by TX queue stats length when
  queues are not allocated.

qlcnic: Fix memory corruption while reading stats using ethtool.

2014-09-26T19:11:31+00:00

o  Driver is doing memset with zero for total number of stats bytes when
   it has already filled some data in the stats buffer, which can overwrite
   memory area beyond the length of stats buffer.

o  Fix this by initializing stats buffer with zero before filling any data in it.
