-Subject: [PATCH] fix MDI-X showing as Unknown instead of "off (auto)"
-
-The current version of ethtool is unable to show the correct MDI-X info:
- # ethtool --version
- ethtool version 6.11
- # ethtool enp0s31f6 | grep MDI
-     MDI-X: Unknown
-
-For comparison, an older version shows it correctly:
- # ./ethtool --version
- ethtool version 6.2
- # ./ethtool enp0s31f6 | grep MDI
-     MDI-X: off (auto)
-
-The blamed commit accidentally removed the ETH_TP_MDI switch case
-in dump_mdix(). As a result, ETH_TP_MDI is treated like Unknown.
-
-Fix it by restoring the ETH_TP_MDI case and breaking out.
-'mdi_x' is initialized to false, which is correct for this case.
-
-Fixes: bd1341cd2146 ("add json support for base command")
