Subject: [PATCH] (resend) ixgbe: always initialize setup_fc

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.
