I'm doing some tests with pktgen and the 8139too (realtek) driver in kernel 2.6.29-rc2.

It seems that netif_tx_queue_stopped will return false fairly often even if the cable is pulled from the NIC.

Is that expected?

Thanks,
Ben

Yep.

Pulling the cable out only effects netif_carrier_ok().

Thanks. I'll just add a check for that as well before I try to transmit.

Thanks,
