I'm observing double the amount of "recv" bytes in latest Centos v6.8 with
ixgbe 4.2.1-k.
Anybody seeing the same?
$ ethtool -i em1
driver: ixgbe
version: 4.2.1-k
$ uname -an
Linux chndcdmid01.rd.ph.cox.net 2.6.32-642.4.2.el6.x86_64 #1 SMP Tue Aug 23
19:58:13 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Doing comparison on 2 days at same hour just to show the difference. This
is an HTTP cache server, having higher RX than TX means something is bad...
We don't rely much on the RECV side, but our graph showed a huge difference
between upgrades.
