Hi,

we would be interested in porting io-net filters to io-pkt as well
and having pfil_run_hooks() calling filter code looks promising.

If doing so, what would be the best way of attaching the filter
code to io-pkt that gets called by pfil_run_hooks()? Could I
write a fake driver which uses only the entry and shutdown
functions and in the entry function instead of calling
dev_attach() I would call pfil_head_register()?
pfil_head_register() would be called on eth_input_pfil_hook for
the rx direction and on the interface hooks of
interest (&ifp->if_pfil) for the tx direction?

Thankful for any help,
