Re: Userspace msg, hw_addr unused?

[Scott MacKay <scottmackay@yahoo.com>]

In poking around, I think I see what would be needed. 
Any confirmation would be great.
entry->skb has a mac.ethernet structure.  This looks
to be a ethhdr, so it has a h_source and h_dest.
2 options seem to be to add a ethdr to the
ipq_packet_msg and memcpy the entry->skb->mac.ethernet
or to add 2 fields (maybe removing the hw_addr if
unused) and memcpy the h_source and h_dest.

I think, if I alter those fields, though, that there
is alot of recompile needed.  Is there a better way to
get to the ethernet fields?
