Hi Sridhar,

I've recently sent some patches regarding stats for the e1000 PMD.

The following commit in git fixed the issue you are experiencing:
67b38d9 e1000: fix total byte statistics

> This works fine on esxi guests using e1000.
I presume you are passing a VF to esxi? The igbvf PMD has a different stats_get() function to the igb PF PMD, so the bug would not be visible there.

As stated, Git includes the fix, along with some more updates like providing extended statistics via the xstats_get() API.

The commit mentioned above is a small code-change and fixes your immediate bug - it will probably apply cleanly to 1.7, otherwise it's an easy backport.
