Subject: [PATCH mlx5-next] net/mlx5: Add IFC bits for PPCNT recovery counters group

From: Yael Chemla <ychemla@...dia.com>

Add recovery counters group layout of PPCNT (Ports Performance Counters
Register). This group counts recovery events per link. Also add the
corresponding bit in PCAM to indicate this group is supported.
