Subject: [PATCH net] selftests: netdevsim: sprinkle more udevadm settle
Date: Sun, 14 Jan 2024 14:47:26 -0800	[thread overview]
Message-ID: <20240114224726.1210532-1-kuba@kernel.org> (raw)

Number of tests are failing when netdev renaming is active
on the system. Add udevadm settle in logic determining
the names.

Fixes: 242aaf03dc9b ("selftests: add a test for ethtool pause stats")
Signed-off-by: Jakub Kicinski <kuba@kernel.org>
