This change removes UDP from the supported protocols for RSS hashing. The
reason for removing this protocol is because IP fragmentation was causing a
network flow to be broken into two streams, one for fragmented, and one for
non-fragmented and this in turn was causing out-of-order issues.

virtio net will never try to overflow the TX ring, so the only reason
add_buf may fail is out of memory. Thus, we can not stop the
device until some request completes - there's no guarantee anything
at all is outstanding.
Make the error message clearer as well: error here does not
indicate queue full.

This patch resolves a number of issues in the statistics gathering of
the s2io driver.
On Xframe adapters, the received multicast statistics counter includes
pause frames which are not indicated to the driver. This can cause
issues where the multicast packet count is higher than what has actually
been received, possibly higher than the number of packets received.
The driver software counters are replaced with the adapter hardware
statistics for rx_packets, rx_bytes, and tx_bytes. It also uses the
overflow registers to determine if the statistics wrapped the 32bit
register (removing the window of having a statistic value less than the
previous call). rx_length_errors statistic now includes undersized
packets in addition to oversized packets in its counting. Finally,
rx_crc_errors are now being counted.

Reducing real_num_queues needs to flush the qdisc otherwise
skbs with queue_mappings greater then real_num_tx_queues can
be sent to the underlying driver.
The flow for this is,
dev_queue_xmit()
dev_pick_tx()
skb_tx_hash() => hash using real_num_tx_queues
skb_set_queue_mapping()
...
qdisc_enqueue_root() => enqueue skb on txq from hash
...
dev->real_num_tx_queues -= n
...
sch_direct_xmit()
dev_hard_start_xmit()
ndo_start_xmit(skb,dev) => skb queue set with old hash
skbs are enqueued on the qdisc with skb->queue_mapping set
0 < queue_mappings < real_num_tx_queues. When the driver
decreases real_num_tx_queues skb's may be dequeued from the
qdisc with a queue_mapping greater then real_num_tx_queues.
This fixes a case in ixgbe where this was occurring with DCB
and FCoE. Because the driver is using queue_mapping to map
skbs to tx descriptor rings we can potentially map skbs to
rings that no longer exist.

The 82576 expects the second rx queue in any pool to receive L2 switch
loop back packets sent from the second tx queue in another pool. The
82576 VF driver does not enable the second rx queue so if the PF driver
sends packets destined to a VF from its second tx queue then the VF
driver will never see them. In SR-IOV mode limit the number of tx queues
used by the PF driver to one. This patch fixes a bug reported in which
the PF cannot communciate with the VF and should be considered for 2.6.34
stable.
