Dear BIRD Developers,

I have tested the Netlink flavor of FreeBSD port. At a glance there are 
at least 2 problems:

1. Memory (resident) usage at the init is about 125% of BIRD 2.13, 
moreover it's constantly growing and after 30 min it was about 300% of 
shown by BIRD 2.13.

2. Some routes are not learned correctly, for example:

Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Invalid route x.y.140.0/22 
withdrawn
Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Invalid route x.y.160.0/22 
withdrawn
Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Invalid route x.y.184.0/22 
withdrawn
Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Invalid route y.y.184.0/24 
withdrawn
Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Malformed bgp_unknown_0x15 
attribute - conflicting flags (e0, expected 80)
Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Malformed bgp_unknown_0x15 
attribute - conflicting flags (e0, expected 80)
Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Malformed bgp_unknown_0xff 
attribute - conflicting flags (e0, expected 80)
Apr 27 20:20:23 rtr bird[40469]: bgp_rmsk_v4: Malformed bgp_unknown_0xff 
attribute - conflicting flags (e0, expected 80)

It came out, that in BIRD 2.13 at least some of these problematic routes 
have special attributes, for example:

BGP.ff [t]: 00 00 07 db 00 00 00 01 00 01 00 0a ff 08 00 00 00 00 ea 44 
42 79

Thanks for giving the opportunity to test !

Cheers
