Hi ,

While accessing MDI_FindPhy  ( MDI utility ) is  not working in custom made driver for tsec0 interface (phy_idx = 0).
 

MDI_FindPhy(mpc85xx->mdi, phy_idx);
MDI_FindPhy required 2 arguments which is mdi_t structure and phy id.

We are getting the interface pointer via “ifunit(“tsec0”)” function.
mpc85xx_dev_t is a low level structure which has stored in ifp->if_softc.  

mdi_t structure is getting from the low level structure(mpc85xx_dev_t) and phyid is 0.

1)    Getting mpc85xx->mdi pointer via ifunit is correct,  is there any other way to get  mpc85xx_dev_t structure from 
custom made driver. 
2)    How to access MDI utilities/library (Ex: MDI_FindPhy, MDI_AutoNegotiate) for tsec0 from custom made driver. 
3)    is that possible to access the MDI (mpc85xx_mii_read/write) registered functions via custom made driver (other 
than mpc85xx ethernet driver )?
4)    How ifconfig utility access the mpc85xx_mii_read/write functions?(Because if we do "ifconfig tsec0 up" which 
invokes the mpc85xx_mii_read function).


Thanks and Regards
