https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230996 Brock Williams <brock@cottonwoodcomputer.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |brock@cottonwoodcomputer.co | |m --- Comment #20 from Brock Williams <brock@cottonwoodcomputer.com> --- We're seeing the same, or at least very similar, issue on 13.0-RELEASE. In our case, we only have the problem if the port is in gigabit mode. If we limit the switch to 100, we don't see the issue. Our configuration is passing a vlan over a bridge interface: ifconfig_igb0="DHCP" ifconfig_igb1="inet 172.28.1.1 netmask 255.255.255.0" dhcpd_ifaces="igb1" vlans_igb0="1501" vlans_igb1="1501" ifconfig_igb0_1501="up" ifconfig_igb1_1501="up" cloned_interfaces="bridge0" ifconfig_bridge0="addm igb0.1501 addm igb1.1501 up" Adding -vlanhwtag to igb0 and igb1 resolves it. pciconf -lv: igb0@pci0:2:0:0: class=0x020000 rev=0x03 hdr=0x00 vendor=0x8086 device=0x1533 subvendor=0x15d9 subdevice=0x1533 vendor = 'Intel Corporation' device = 'I210 Gigabit Network Connection' class = network subclass = ethernet -- You are receiving this mail because: You are the assignee for the bug.
