The congestion management code has migrated into a common location,
allowing all fw writes controlling mf congestion to be made in a

Restore remote-faule detection, which periodically checks for
remote-fault on the MAC layer. In case physical link appear to be
up but fault is set, it will provide a link down indication, and
when the fault is cleared, it will indicate link up again.

Until now, the bnx2x driver needed at least 2 available msix interrupt
vectors in order to use msix. This patch add the possibility of configuring
msix when only one interrupt vector is available.

remove unnecessary code that matches this coccinelle pattern

	ret = phy_write(x, y , z)

As phy_write returns error code, we dont need to do not need extra check

In the existing code, we only stop queue when the ringbuffer is full,
so the current packet has to be dropped or retried from upper layer.

This patch stops the tx queue when available ringbuffer is below
the low watermark. So the ringbuffer still has small amount of space
available for the current packet. This will reduce the overhead of
retries on sending.

unix_dgram_sendmsg() currently builds linear skbs, and this can stress
page allocator with high order page allocations. When memory gets
fragmented, this can eventually fail.

We can try to use order-2 allocations for skb head (SKB_MAX_ALLOC) plus
up to 16 page fragments to lower pressure on buddy allocator.

This patch has no effect on messages of less than 16064 bytes.
(on 64bit arches with PAGE_SIZE=4096)

For bigger messages (from 16065 to 81600 bytes), this patch brings
reliability at the expense of performance penalty because of extra pages
allocations.
