hello, I am compiling kernel for 88f6281 with 88e6161 switch for 4.9.73.but the dsa does not work correctly.I think it is a bug because 4.4 and 4.14 works fine.
both two bindings get the same result (port uninitialized, could not setup slave phy -19). thanks
this it the log

Please could you try cherry-picking:

ec8378bb4d8e ("net: dsa: mv88e6xxx: 6161 uses global 2 for PHY access")
0ac64c394900 ("net: dsa: mv88e6xxx: mv88e6161 uses mv88e6320 stats snapshot")
5ebe31d7b20f ("net: dsa: mv88e6xxx: Have 6161/6123 use EDSA tags")

The first one probably fixes your PHY issue. The second will fix
ethtool -S. The last one is just nice to have, helps when using
tcpdump on the master interface.

Thanks go to Chris Healy for pointing out these patches.
