You seem to have the following problem: if_bridge(4) tries to disable TXCSUM on all members added. But you add if_lagg(4), which doesn't pass those requests to it's members, but simply ignores the request. So you need to manually -txcsum (-txcsum6), e.g. in rc.conf when you set them "up". Unofrtunately I don't know how offloading is implemented generally, nor how it works for if_igb(4), so I haven't thought about the reason yet, why you need to disable TXCSUM. Much more important, does it also affect TSO? I can't tell, maybe someone with more knowledge can jump in. -harry _______________________________________________ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
