BIRD removing BGP routes from other daemon - FreeBSD

[Cassiano Peixoto]

Hi Ondrej,

Thanks for your help. I've changed as you suggested
on sysdep/bsd/krt-sock.c to PROTO2 and i worked fine.

I'd would like know what kind of problem i would have if i keep this change
on my bird. Can i run into some issues with other protocols or systems?

Thanks.
