Subject: pktgen multiqueue oops
Date: Mon, 27 Aug 2007 11:16:19 +0200	[thread overview]
Message-ID: <18130.38499.765184.425431@robur.slu.se> (raw)


Hello,

Initially pkt_dev can be NULL this causes netif_subqueue_stopped to 
oops. The patch below should cure it. But maybe the pktgen TX logic 
should be reworked to better support the new multiqueue support. 

Cheers
