https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D282095 --- Comment #5 from Doug Ambrisko <ambrisko@FreeBSD.org> --- I haven't tried MTU changes. I might have to block that since I thought pe= ople on the Linux side said changing the MTU was not supported without a VIC configuration change (via BMC UI) and OS reboot. I didn't connect the vari= ous offloads that the card supports. I'll need to poke around at that. I shou= ld look at adding devcmd2 support. Currently the driver supports basic connectivity. The VIC card is not a typical NIC. The checksum and VLAN offload should be easy to add support since the API into the card is there but I never attached to the FreeBSD API. devcmd2 is a bit more involved since it requires another write queue for that. It would be great= if you could try it with Linux to compare features. Then I can dig into it. = It seems with iflib it requires pairs of TX/RX queues. The driver looks at th= e RX and TX queue configuration and uses the smallest value. You might check the configuration and see if bumping up the number of queues help. I think by default the number of TX queues is only 1. I haven't looked at SR-IOV. Thanks for playing with it, hopefully you find it useful. My main goal was= to be able to PXE boot and run machines diskless especially blades that only h= ave this NIC. If someone wants to look at the offload and send me patches that would be great. --=20 You are receiving this mail because: You are the assignee for the bug.=
