We could get rid of these (and others) if we'd filter the network-modules
for the call 'eth_type_trans' (nm -uPA ... | grep eth_type_trans)

Hmmm... Would it make sense if the network installer would just specify
which modules below /kernel/net are needed and only /kernel/drivers/net
is process automatically?

Add 

nm -uPA $srcmods/$(modprobe -l $mod) | egrep -qv 'ieee802011|wireless' || return

To to just before the modprobe inside instmods and wireless drivers should be gone
