(In reply to mike from comment #48)
I suppose the same applies to handling incoming packets, which means adding
CURVNET_SET_QUIET(vnet0);/CURVNET_RESTORE(); around ifp->if_input(ifp, m); as
per the updated patch. (Right after/before unlocking/locking)

Note that in the meantime I have started looking at how to reflect the media in
ifconfig(8) (e.g., GPRS/EDGE/LTE...) which explains the presence of new changes
in sys/net/if_media.* and lib/libifconfig; this bit is in progress, you can
ignore it for now. (It should not harm anything either way)
