====================
Support both XIVE and XICS modes in ibmvnic

This series aims to support both XICS and XIVE with avoiding
a regression in behavior when a system runs in XICS mode.

Patch 1 reverts commit e5f9c071ecb517da319f811fd844f1f254c33ba0
(“net/ibmvnic: Fix EOI when running in XIVE mode.”)

Patch 2 Ignore H_FUNCTION return from H_EOI to tolerate XIVE mode
