Indeed, bringing up intrefaces this way: ifconfig_igb0=3D"mtu 9000 -vlanmtu -vlanhwtag -vlanhwfilter -vlanhwtso -vlanhwcsum up" ifconfig_igb1=3D"mtu 9000 -vlanmtu -vlanhwtag -vlanhwfilter -vlanhwtso -vlanhwcsum up" makes vlan(4) children brought up with mtu 8996, but IMHO it's not right solution of the problem. 2. I also tried to apply D33154 as suggested =C3=96zkan KIRIK on net@ maili= ng list: > Please see the https://reviews.freebsd.org/D33154, > igb driver doesn't honor the interface capabilities like vlanhwtag, > vlan* and etc now. If you want, you can apply the patches from D33154 The patch unfortunately doesn't solve this issue. FYI, in another machine, I have the setup described below working flawlessly with the same 13.0-STABLE revision. em0: flags=3D8963 metric 0 = mtu 9000 =20=20=20=20=20=20=20 options=3D481049b em1: flags=3D8963 metric 0 = mtu 9000 =20=20=20=20=20=20=20 options=3D481049b lagg0: flags=3D8943 metric = 0 mtu 9000 =20=20=20=20=20=20=20 options=3D481049b ether 00:26:55:e4:d3:fa laggproto lacp lagghash l2,l3,l4 laggport: em0 flags=3D1c laggport: em1 flags=3D1c vlan6: flags=3D8843 metric 0 mtu 90= 00 options=3D4000403 vlan: 7 vlanproto: 802.1q vlanpcp: 0 parent interface: lagg0 --=20 You are receiving this mail because: You are on the CC list for the bug.=
