[PATCH 6.4 111/206] selftests: forwarding: ethtool: Skip when using veth pairs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ido Schimmel <idosch@xxxxxxxxxx>

commit 60a36e21915c31c0375d9427be9406aa8ce2ec34 upstream.

Auto-negotiation cannot be tested with veth pairs, resulting in
failures:

 # ./ethtool.sh
 TEST: force of same speed autoneg off                               [FAIL]
         error in configuration. swp1 speed Not autoneg off
 [...]

Fix by skipping the test when used with veth pairs.

Fixes: 64916b57c0b1 ("selftests: forwarding: Add speed and auto-negotiation test")
