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.
