Re: [dts] [PATCH V1] tests/vf daemon fix make queues full fail

["Liu, Yong" <yong.liu@intel.com>]

Meijuan,
Your git commit is not accurate, the number of descriptors are changed because of testpmd will use driver default setting. This value maybe changed as different NICs will have different settings. 

I recommend you to fix this value by testpmd "--rxd" parameters, thus this value can be aligned between all NICs.

Thanks,
Marvin
