TBI PHY address (TBIPA) register is set in general frame manager phy init funciton dtsec_init_phy() in drivers/net/fm/eth.c, and it is supposed to set TBIPA on FM1@DTSEC1 in case of FM1@DTSEC1 isn't used directly, which provides MDIO for other ports. So following code is wrong in case of FM2, which has a different mac base.
Is this still true with Fman v3?
[S.H] No. Fman V3 does not need to set TBIPA on FM1@DTSEC1.
Does this patch fix any known bugs?
[S.H] Yes, it fixed a bug internally (ENGR224292: p4080ds FM2@DTSEC4 can't ping), and I sent it upstream as Kumar suggested.
