This patch adds support so that the rps_flow_tables (RFS) can be
programmed using the tun flows which are already set up to track flows
for the purposes of queue selection.

On the receive path (corresponding to select_queue and tun_net_xmit) the
rxhash is saved in the flow_entry.  The original code only does flow
lookup in select_queue, so this patch adds a flow lookup in tun_net_xmit
if num_queues == 1 (select_queue is not called from
dev_queue_xmit->netdev_pick_tx in that case).

The flow is recorded (processing CPU) in tun_flow_update (TX path), and
reset when flow is deleted.

This patch adds sock_rps_record_flow_hash and sock_rps_reset_flow_hash
which take a hash value as an argument and sets the sock_flow_table
accordingly.  This allows the table to be populated in cases where flow
is being tracked outside of a sock structure.

sock_rps_record_flow and sock_rps_reset_flow call this function
where the hash is taken from sk_rxhash.

When we set burst to 1514 with low rate in userspace,
the kernel get a value of burst that less than 1514,
which doesn't work.

Because it may make some loss when transform burst
to buffer in userspace. This makes burst lose some
bytes, when the kernel transform the buffer back to
burst.

This patch adds two new attributes to support sending
burst/mtu to kernel directly to avoid the loss.

bnx2x: new features patch series

This patch series adds/fixes several new features in the bnx2x driver -
it adds support for loading the bnx2x over an UNDI running on a Multi-function
device, adds missing bits for PCIe AER support and enables VFs to properly
configure multicast filters
(In addition, it also contains some small improvements in driver behaviour).

Please consider applying these patches to `net-next'.

It's possible for VMs with older versions of bnx2x to run over a hypervisor
with latest driver. If a VF in such a VM does not support RSS configuration,
the PF driver in the hypervisor will print an error message to system logs.

This changes the error message into a debug message, as this is very likely
a false alarm for an older VF (i.e., VF manages to work properly; PF simply
cannot configure the additional queues for it).
