macvlan: 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/macvlan.c: In function ‘macvlan_do_ioctl’:
drivers/net/macvlan.c:839:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!net_eq(dev_net(dev), &init_net))
^
drivers/net/macvlan.c:841:2: note: here
case SIOCGHWTSTAMP:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
