Jan,
	Yes, these patches are for transmit multiqueue hardware support
only.  There are other efforts to stop using the fake netdevices for Rx
polling, such as using MSI-X vectors assigned to particular receive
queues, but this is still done in the driver (which is ok).  I'm
currently not working on anything in the kernel to support multiqueue Rx
for non MSI-X devices though.

Thanks,
