Subject: [PATCH] net: ethernet: mediatek: Fix overlapping capability bits.
Both MTK_TRGMII_MT7621_CLK and MTK_PATH_BIT are defined as bit 10.
This causes issues on non-MT7621 devices which has the
MTK_PATH_BIT(MTK_ETH_PATH_GMAC1_RGMII) capability set.
The wrong TRGMII setup code is executed.
Moving the MTK_PATH_BIT to bit 11 fixes the issue.
Fixes: 8efaa653a8a5 ("net: ethernet: mediatek: Add MT7621 TRGMII mode
support")
