vlan: 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:
net/8021q/vlan_dev.c: In function ‘vlan_dev_ioctl’:
net/8021q/vlan_dev.c:374:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!net_eq(dev_net(dev), &init_net))
^
net/8021q/vlan_dev.c:376:2: note: here
case SIOCGMIIPHY:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
