Subject: IB/mlx5: Expose more priorities for bypass namespace
Patch-mainline: v4.17-rc1
Git-commit: 72f7cc09b143cf972c8c7571fc95d1017ba76c3d
References: bsc#1103991 FATE#326007

BYPASS namespace is used by the RDMA side to insert flow rules into
the vport RX flow tables. Currently only 8 priorities are exposed,
increase this to 16 to allow more flexibility. This change will also
cause the BYPASS namespace to use 32 levels (as apposed to 16 today) of
flow tables, 16 levels for regular rules and 16 for don't trap rules.
