From a2c6b87dd08cdfc2d065d4ae369e4e747b521a7f Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Mon, 8 Jul 2019 23:17:36 -0500 Subject: devlink: Return physical port fields only for applicable port flavours Physical port number and split group fields are applicable only to physical port flavours such as PHYSICAL, CPU and DSA. Hence limit returning those values in netlink response to such port flavours. Acked-by: Jiri Pirko Signed-off-by: Parav Pandit Signed-off-by: David S.
