[dpdk-dev] [PATCH v3 3/4] net/bond: dedicated hw queues for LACP control traffic

[Linhaifeng]

Hi, Tomasz

Thanks for the reply!

I thought that the patch was used to resolve the "lacp loss" problem. We know when the traffic is large enough 
 bond may loss the lacp packets and slave would out of sync.

My question is, are there any solutions to solve the "lacp loss" problem?

This is performance improvement.
