amd-xgbe: Check for Tx hardware queue flushing support
The flushing of the Tx hardware queues is only supported at a certain level of the hardware. Retrieve the current version of the hardware and use that to determine if flushing is supported. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
