7.81 GRO Must Be Disabled After an Upgrade When Routing/Bridging with IXGBE Driver

A kernel issue requires that Generic Receive Offload (GRO) be disabled when routing or bridging wiht the IXGBE driver. This issue has been fixed for fresh installs, but if you are upgrading to the current release from a release prior to Oracle VM Server 3.3.3, you must disable GRO manually yourself.

Workaround: Disable GRO manually on each affected Oracle VM Server, using ethtool:

# ethtool -K ethX gro off
