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.
