MFLCN register is used to set Rx flow control on parts newer than 82598.

This patch sends the value of MFLCN to ethtool, so it can be used in a
register dump (ethtool -d).

It some situations the driver sets __IXGBE_RESETTING and then
__IXGBE_DOWN flags. It is possible a link check may sneak in
between.

This patch adds check for both flags.
The idea is to reduce register reads while the PHY is resetting.

drivers/scsi/built-in.o:(.text+0x17f9a0): first defined here

This patch renames bfa_ioc_ct2_poweron() to bfa_nw_ioc_ct2_poweron() to avoid
multiple definition with Brocade scsi driver. It also modifies asic specific
interface setup to allocate MSIX resources at power on in case of 1860 HW with
no asic block and warns if the asic gen is neither BFI_ASIC_GEN_CT nor
BFI_ASIC_GEN_CT2.

When port is added to a bridge, the old code would send the new neighbor

is moved earlier in the process to avoid having to do unwind.

 - Add a callback in the BNA, which is called before sending FW command to stop
   RxQs. After this callback is called, driver should not post anymore Rx
   buffers to the RxQ. This addresses a small window where driver posts Rx
   buffers while FW is stopping/has stopped the RxQ.
 - Registering callback function, rx_stall_cbfn, during bna_rx_create.
