b715ce947f tg3: Fix link down notify failure when EEE disabled
Occasionally, when the network cable is removed after a successful
autonegotiation, the device will not send a link down interrupt to the
driver.  This happens because of a bad interaction of an EEE

condition does not happen.

Commit f2096f94b5, entitled
"tg3: Add 5720 H2BMC support", needed to add code to preserve some bits

7961689586 bnx2x: Broken self-test in SF mode on 578xx
This patch fixes both the failure in the self-test on 578xx
and a hole in a parity recovery flow that this failure
has discovered:
 - internal 'pending' state in a VLAN_MAC object wasn't been cleared
when the object state change was called with DRV_ONLY flag, which in
particular happens when a parity error happens during the self-test.
 - bp->sp_state wasn't cleared in the similar circumstances as described
above.

bab632d69e vhost: vhost TX zero-copy support
>From: Shirley Ma <mashirle@us.ibm.com>

This adds experimental zero copy support in vhost-net,
disabled by default. To enable, set
experimental_zcopytx module option to 1.

This patch maintains the outstanding userspace buffers in the
sequence it is delivered to vhost. The outstanding userspace buffers
will be marked as done once the lower device buffers DMA has finished.
This is monitored through last reference of kfree_skb callback. Two
buffer indices are used for this purpose.

The vhost-net device passes the userspace buffers info to lower device
skb through message control. DMA done status check and guest
notification are handled by handle_tx: in the worst case is all buffers
in the vq are in pending/done status, so we need to notify guest to
release DMA done buffers first before we get any new buffers from the
vq.

One known problem is that if the guest stops submitting
buffers, buffers might never get used until some
further action, e.g. device reset. This does not
seem to affect linux guests.
