Subject: Reg - MII Driver

Hi,

i m going to develope a new MII driver for my PHY for that i refered
some of the sample driver in QNX from path (/sys/dev/mii/gentbi.c
,Ikphy.c,Inphy.c), In that files  they are invoking PHY_READ/WRITE
function but they have nt register mii_read /write functions.

Which mii_read/write function assoicated with that driver?

Can you please help on this.

Thanks and Regards
K.Senthil

I really doubt you will need to do that.  The IEEE802.3u
standard specifies the layout and the values of the PHY
registers, which our libdrvr complies with.

Unless your PHY does not comply with the standard,
you do not need to modify the MDI_ libdrvr source
which is statically linked into the network drivers.

That's what you need to write - nic (and possibly
board) specific functions to read and write PHY
registers, which usually involves reading and
writing registers on the NIC, often with timing
delay loops.

Once you have implemented the PHY read/write 
registers, generally they just work.  You may need
to put a little bit of board-specific setup code
in the init_phy() function in the driver mii.c
file, but that's it.

Oh yeah, there is another callback function in
the mii.c file which you might want to implement - 
the main reason is that you might need to program
the link duplex into a nic register.

Look at some of the mii.c driver source for ideas.
