https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235031 --- Comment #17 from Martin Birgmeier <d8zNeCFG@aon.at> --- Because bug #234550 might be related to this one, I tried to issue "ifconfig -lro em0". This resulted in the interface not working anymore, with the alr= eady known syslog messages: Jan 20 09:29:18 mizar kernel: em0: link state changed to DOWN Jan 20 09:29:20 mizar kernel: em0: TX(0) desc avail =3D 1024, pidx =3D 0 Jan 20 09:34:36 mizar kernel: em0: TX(0) desc avail =3D 1024, pidx =3D 0 Jan 20 09:34:42 mizar kernel: em0: TX(0) desc avail =3D 1024, pidx =3D 0 Jan 20 09:34:51 mizar kernel: em0: TX(0) desc avail =3D 1024, pidx =3D 0 Jan 20 09:34:54 mizar kernel: em0: TX(0) desc avail =3D 1024, pidx =3D 0 None of the following commands (from the shell history) helped: 4981 2019-01-20 09:29 0:01 ifconfig em0 -lro 4982 2019-01-20 09:29 0:00 ifconfig em0 up 4985 2019-01-20 09:30 0:00 ifconfig em0 4987 2019-01-20 09:30 0:03 ifconfig em0 lro up 4989 2019-01-20 09:31 0:00 ifconfig em0 4990 2019-01-20 09:32 0:00 ifconfig em0 down 4991 2019-01-20 09:32 0:02 ifconfig em0 up 4999 2019-01-20 09:40 0:00 ifconfig em0 Then I tried adding "-lro" in rc.conf: ifconfig_em0=3D"-lro inet $hostname" This resulted in a rather long wait for the interface to be available to so= me rc processes. When the machine was finally up, NFS to it did not work at al= l, it just hung. I removed the -lro flag again. What is the issue that using ifconfig on this interface breaks it? -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
