igb: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
This patch fixes the following warning:
drivers/net/ethernet/intel/igb/igb_main.c: In function ‘__igb_notify_dca’:
drivers/net/ethernet/intel/igb/igb_main.c:6694:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (dca_add_requester(dev) == 0) {
^
drivers/net/ethernet/intel/igb/igb_main.c:6701:2: note: here
case DCA_PROVIDER_REMOVE:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
