RE: [802.3ae] some questions about mdio




The MDIO/MDC operate very similar to an I2C interface.  The MDIO carries the
data in a serial stream.  Within the data on the serial stream, there are
two bits used to indicate reads and writes.  This information can be found
in Clause 22 of 802.3-2000 and in Clause 45 of P802.3ae.

Cheers,
Brad

	hi,
	I  know  that  mdio  is  the  management interface  between the  sta
and 
	phy,
	but where the write and read command come from? And, if  they  is 
	determined by some register,then what the registers are and where
they come 
	from?

	                                                         thank,
	                                                            amyliya
