Subject: [PATCH] powerpc/powernv/pci: Drop VF MPS fixup
Date: Wed, 2 Sep 2020 13:51:59 +1000 [thread overview]
Message-ID: <20200902035159.1762596-1-oohall@gmail.com> (raw)
The MPS field in the VF config space is marked as reserved in current
versions of the SR-IOV spec. In other words, this fixup doesn't do
anything.
