Whenever there is a physical link change, using this mapping driver forwards the message to the associated netdev. This patch prints error message incase of cgx,lmac pair is not associated with any pf netdev. Signed-off-by: Hariprasad Kelam Signed-off-by: Sunil Kovvuri Goutham Signed-off-by: David S.
