Jon Hunter reported observing a build bug in the IPA driver: https://lore.kernel.org/netdev/[email protected]
The problem is that the QMB0 max read value set for IPA v4.5 (16) is too large to fit in the 4-bit field. This is a quick fix to resolve the build bug; this might change again in the future if I learn there is a better value to use.
