Hi Thomas, Xiaoyun,

With this patch (commit 84cc318424d49372dd2a5fbf3cf84426bf95acce) I see
more than 20% performance drop in vhost loopback test with testpmd
macswap for 256 bytes packets, which means it impacts actual vSwitching
performance.

Suggest we fix it or revert it for this release.

Thanks
Zhihong
