    Subject[PATCH AUTOSEL 4.14 24/59] bnx2x: Clear fip MAC when fcoe offload support is disabled
    Date
    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.
