Subject: [PATCH net v1] net: dsa: lantiq_gswip: fix and improve the unsupported interface error
Date: Sun, 7 Jun 2020 15:02:58 +0200 [thread overview]
Message-ID: <20200607130258.3020392-1-martin.blumenstingl@googlemail.com> (raw)
While trying to use the lantiq_gswip driver on one of my boards I made
a mistake when specifying the phy-mode (because the out-of-tree driver
wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the
following error is printed multiple times:
Unsupported interface: 3
While it gives at least a hint at what may be wrong it is not very user
friendly. Print the human readable phy-mode and also which port is
configured incorrectly (this hardware supports ports 0..6) to improve
the cases where someone made a mistake.
Fixes: 14fceff4771e51 ("net: dsa: Add Lantiq / Intel DSA driver for vrx200")
