While trying to get pktgen to effectively use VLANs to send traffic,
I noticed that the vlan code always returns 0 from it's hard_start_xmit
method. Since it calls dev_queue_xmit inside that method, I tried
returning the value that dev_queue_xmit returns. It seems that the
return values have different meanings because this causes crashes due
to freeing skbs when I shouldn't be...
The dev_queue_xmit method is fairly well documented in dev.c, but
there are zero comments in the netdevice.h file to explain what the
acceptable return values for hard_start_xmit are.
Does anyone know if there is a definative guide to the return values
for hard_start_xmit?
Thanks,
Ben
