Hi, if.c has grown dependencies on loop and ether; if you remove the pseudo devices from your kernel config it won't link anymore: if.o: In function `ifa_maintain_loopback_route': /tank/users/bz/github/fbdz/sys/net/if.c:1703: undefined reference to `loif' if.o: In function `if_etherbpfmtap': /tank/users/bz/github/fbdz/sys/net/if.c:4093: undefined reference to `ether_vlan_mtap'
