Gmail mangled my first message, sorry about that. Second attempt.In ixgbe_init_mac_link_ops_X550em, the code has a special case for backplane media type, but does not fall through to the default case, so the setup_fc never gets initialized. This causes a panic when it later tries to set up the card, and the kernel dereferences the null pointer. This patch lets the the function fall through, which initialized setup_fc properly.
I don't think that this is the right fix. My memory is that fc autoneg is not supported in that configuration, so setup_fc is intended to be NULL. I think it is the reference that needs to have a check added.
