| |
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ 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.
