Please, use a different DLT than radiotap's (DLT_IEEE802_11_RADIO)
to inject non-radiotap headers.

When I made a similar patch for a customer, I added to bpf a bpfattach3()
call that sets a new bpf_if member, bif_output, to ieee80211_output().
I made ieee80211_output() grok both AF_UNSPEC and pseudo_AF_HDRCMPLT,
which is sometimes handy.  I probably cannot open-source the patches
any time soon, *sigh*.
