From 995b2a65232f9bd54d8e41a7669436a93698bf01 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Sat, 24 Feb 2018 18:27:25 -0500 Subject: [PATCH] net/sonic: Replace custom debug logging with netif_* calls Eliminate duplicated debug code by moving it into the core driver. Don't log the only valid silicon revision number (it's in the source). Cc: Thomas Bogendoerfer Cc: Chris Zankel Tested-by: Stan Johnson Signed-off-by: Finn Thain Signed-off-by: David S.
