https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230996 Jason Tubnor <jason@tubnor.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason@tubnor.net --- Comment #4 from Jason Tubnor <jason@tubnor.net> --- This issue still exists in 12.1-p1 While vlanhwtagging doesn't need to be disabled if using the host in a vani= lla config, once and igb interface is placed into a bridge as a vlan with a tap device for a bhyve guest, ingress of data to the guest comes to a halt und= er iperf3 testing. egress from the guest is not impacted and runs at full spee= d. When vlanhwtagging is disabled, forcing the host to perform the function, d= ata ingress or egress of the guest runs at full speed. I'd like to enable vlanhwtagging as the CPU load put on the host is huge wh= en transferring a single 1Gb/s stream of traffic from guests. --=20 You are receiving this mail because: You are the assignee for the bug.=
