Not sure about but it definitely worked in ESXi5.5 Update1, and also prior versions. Also on ESXi6.0 it works fine.
We are using 1rx queue and 8 tx queues per port. The nb_rx_desc is set to 4096 and the each mbuf size is set to 2048. The rx_conf struct has the following values during the init time .
static const struct rte_eth_rxconf rx_conf = {
.rx_thresh = {
.pthresh = RX_PTHRESH,
.hthresh = RX_HTHRESH,
.wthresh = RX_WTHRESH,
},
};
Do you suspect anything wrong in this ?

Did it work for ESXi 5.5 update 2 or some earlier version?
Can you also post the rx ring size you used to config the rx queue?
In update 3, there are some changes to the max allowed rx ring size for ring1. Even ring1 is not used yet in the pmd, the setup code sets ring1’s size the same as ring0’s.
