In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
This patch fixes the following warnings:
drivers/net/ethernet/intel/igb/e1000_82575.c:636:6: warning: this statement may
fall through [-Wimplicit-fallthrough=]
drivers/net/ethernet/intel/igb/igb_main.c:6710:6: warning: this statement may
fall through [-Wimplicit-fallthrough=]
drivers/net/ethernet/intel/i40e/i40e_xsk.c:237:3: warning: this statement may
fall through [-Wimplicit-fallthrough=]
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.
