Attached the patch with the corrections. By the way, who frees the mc mbuf
which is passed to ifp->if_input ?

Submit #3126: Bring in BIOC{S,G}FEEDBACK

Hi,
The port net/vde2 uses a ioctl command BIOCFEEDBACK for FreeBSD to allow
host-guest communication in a vde switch. The attached patch is the initial
attempt to bring that ioctl command from NetBSD.
It compiles but it's untested until I figure out how to test it.
I'd need some pointers though:
- Is it okay to use directly ifp->if_input directly? Isn't there a mechanism
similar to the one used in bpfwrite() -> bpf_output_dispatch but for input?
- If it's okay to use ifp->if_input directly, wouldn't it need some locking?
Cheers,
Antonio Huete
