To allow brport device to return current brport flags set on port.  Add
returned flags to nested IFLA_PROTINFO netlink msg built in dflt getlink.
With this change, netlink msg returned for bridge_getlink contains the port's
offloaded flag settings (the port's SELF settings).

In the RX path, the driver currently consumes upto 64 (budget) packets in
one NAPI sweep. When the size of the packet received is larger than a
fragment size (2K), more than one fragment is consumed for each packet.
As the driver currently posts a max of 64 fragments, all the consumed
fragments may not be replenished. This can cause avoidable drops in RX path.
This patch fixes this by posting a max(consumed_frags, 64) frags. This is
done only when there are atleast 64 free slots in the RXQ.

Old versions of BE3 FW may not support cmds to re-provision (and hence
optimize) resources/queues in SR-IOV config. Do not treat this FW cmd
failure as fatal and fail the function initialization. Instead, just
enable SR-IOV with the resources provided by the FW.

Prior to the "create optimal number of queues on SR-IOV config" patch
such failures were ignored.

irqs.  Once this completes be2net completes pci_disable_msix

or not. But, the patch bec84e6b("create optimal number of queues on SR-IOV

much before SR-IOV is enabled. So, we now use an explicit flag to track
SR-IOV enabled state.
