  To improve performance in vhost Tx/Rx, merge vhost stats loop.
eth_vhost_tx has 2 loop of send num iteraion.
It can be merge into one.
eth_vhost_rx has the same issue as Tx.

Fixes: 4d6cf2ac93dc ("net/vhost: add extended statistics")

Please remove the Fixes tag, this is an optimization, not a fix.

I tried to build without and with your patch, and I think that what can
explain most of the performance difference is that without your patch
the function is not inlined, whereas it is implicitely inlined with your
patch applied.

I agree with your patch, but I think we might add __rte_always_inline to
this function to make it explicit. What do you think?

Other than that:

Hi, Maxime
I agree with you.The inline should be added to vhost_update_single_packet_xstats function.
I will fix it in [PATCH v3].

Thanks,
Gaoxiang
