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.
