With reference to the discussion at
and the follow-up by Manuel Bouyer, it looks like the cause of
this problem is that the bnx driver is missing support for the
SIOCINITIFADDR, which the agr driver uses.
Bonding two wm interfaces together works with now special
handwaves, and that driver does indeed support the
Try to bond together two bnx interfaces without doing anything
to align the MAC addresses of the two before.
Watch one of the interfaces not being accepted by the remote
end because the source MAC ends up different from the other
No suggested fix submitted for now.
A possible workaround is to use ifconfig to set the MAC
address identically on two bnx interfaces you want to bond
together with agr, and it is then rumoured that agr will work
as intended across the two interfaces.
ifconfig uses the SIOCALIFADDR ioctl.
