Re: no hugepage with UIO poll-mode driver

[Younghwan Go <yhwan@ndsl.kaist.edu>]

Hi Jianfeng,

Thanks for the email. rte mempool was successfully created without any 
error. Now the next problem is that rte_eth_rx_burst() is always 
returning 0 as if there was no packet to receive... Do you have any 
suggestion on what might be causing this issue? In the meantime, I will 
be digging through ixgbe driver code to see what's going on.

Thank you,
Younghwan
