Numbers of Ipkts and Oerrs are close enough and Opkts is too small compared to Ipkts, so I believe the driver misbehaves a bit and erroneously shows number of output packets as Oerrs. The Obytes also seems to be too small to be correct. A few months ago the association with AP starts sometimes to stall with no traffic in/out at all, reconfig in wpa_cli helps then. Looks like it correlates with upgrade from 10-stable to 11, but I'm not so sure. > Kevin Oberman, Part time kid herder and retired Network Engineer > E-mail: rkoberman@gmail.com > PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 > _______________________________________________ > freebsd-net@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" >=20 --=20 Hrant Dadivanyan (aka Ran d'Adi) hrant(at)dadivanyan.net /* "Feci quod potui, faciant meliora potentes." */ ran(at)psg.com --EFzZB0nIKSOARE3GbWaxnG9s94Hh4SyZ4-- --kgpODPCG5IIObaum9OJ5rmhpEs2a9hyeB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEzBAEBCAAdFiEEPbz+l3tnoK718ci3h/fmw7c/bD0FAlrZeggACgkQh/fmw7c/ bD0vEwf9FAobn/xZer/96tzMUz1oOx8hayZUTHuIqIIBXtW4fqUrq8zM8qgT4V/N yclC1Zm0wH8r2eyWEd5fx27J5uY04vlNgWsHaYjqyhBW7YVryHN5kaV45vyySeQG u1XZSGxHGnLBwWww7hACElY8BWEptuY+n/m23w/yFyRHkD9amSTlkvJmPPjMr2LS rKkMoojiR89zN2oLZVWXzK6PJCGesW/j+9eeiVLoL9HCmmLpugXezCrBi5Ln//bE fTZh1gW1HGjz/M/x/Bj+3YhGjvf8yJrZIb1ftamzrYTgQqbBfYKB68fvhP6G1059 hzf0XKdzcRF7OXvcVtyEucRMtQPWJg== =wZBT -----END PGP SIGNATURE----- --kgpODPCG5IIObaum9OJ5rmhpEs2a9hyeB--
