From: Sudarsana Reddy Kalluru <sudarsana.kalluru@cavium.com>

[ Upstream commit bbf666c1af916ed74795493c564df6fad462cc80 ]

On some customer setups it was observed that shmem contains a non-zero fip
MAC for 57711 which would lead to enabling of SW FCoE.
Add a software workaround to clear the bad fip mac address if no FCoE
connections are supported.
