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/3com/3c509.c:1265:8: warning: this statement may fall
through [-Wimplicit-fallthrough=]
drivers/net/ethernet/3com/3c509.c:1271:8: 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.
