I got that - it is what tg3 does for example.
To mimick that behavior in LLTX, a driver needs to use the same lock on
both tx and receive. e1000 holds a different lock on tx path from rx
path. Maybe theres something clever i am missing; but it seems to be a
bug on e1000.
The point i was making is that it was strange i never had problems
despite taking away the lock on the tx side and using the rx side
concurently.
cheers,
