Subject: net: mvpp2: use only one rx queue per port per CPU
Patch-mainline: v4.19-rc1
Git-commit: f8c6ba8424b0fa5e001c23a30099351170f5be0d
References: bsc#1119113 FATE#326472

The number of receive queue per port is :
 - MVPP2_DEFAULT_RXQ if in single queue mode
 - MVPP2_DEFAULT_RXQ * num_possible_cpus if in multi queue mode

with MVPP2_DEFAULT_RXQ = 4.

However, we don't use the extra rx queues at the moment, we really only
need one per port per CPU, until some more advanced classification rules
are implemented.
