Subject: [PATCH] ibmvnic: Introduce driver limits for ring sizes
References: bsc#1121726
Patch-mainline: v4.20-rc1
Git-commit: 20b5ba1f610079908b70d44fd7fb91bf0e9700ff
Introduce driver-defined maximums for queue ring sizes. Devices
available for IBM vNIC today will likely not allow this amount,
but this should give us some leeway for future devices that may
support larger ring sizes.
