From b3c898e20b1881b0876c3e811c58b039b37dd5fd Mon Sep 17 00:00:00 2001 From: Debabrata Banerjee Date: Wed, 16 May 2018 14:02:13 -0400 Subject: Revert "bonding: allow carrier and link status to determine link state" This reverts commit 1386c36b30388f46a95100924bfcae75160db715. We don't want to encourage drivers to not report carrier status correctly, therefore remove this commit. Signed-off-by: Debabrata Banerjee Signed-off-by: David S.
