[dpdk-dev] [PATCH v2] igb: fix i350 VF RX issue

[Thomas Monjalon]

> A problem is found on i350 VF. We found TX will happen once
> per 4 packets. If only 1~3 packets are received, they will
> not be forwarded. But the real problem is on RX side. The
> reason is the default RX write-back threshold is changed to
> 4, so every first 3 packets may be hung there.
> 
> This patch checks the RX wthresh when setting up the RX
> queue, and forces it to be 1, so every packet can be handled
> immediately.
> 
> v2:
> - Add missed signoff.
> 
> Fixes: 4a41c17dba18 (igb: set default thresholds based on MAC type)
