From fe8300fd8d655ebc6b6297565665959d6d7bbe02 Mon Sep 17 00:00:00 2001 From: Taehee Yoo Date: Fri, 25 Sep 2020 18:13:02 +0000 Subject: net: core: add __netdev_upper_dev_unlink() The netdev_upper_dev_unlink() has to work differently according to flags. This idea is the same with __netdev_upper_dev_link(). In the following patches, new flags will be added. Signed-off-by: Taehee Yoo Signed-off-by: David S.
