<font face="Arial"> Thanks that proved useful. I am already using
gianfar as a reference - but it is not a NIC I am familiar with.<br>
And I still have some questions:<br>
<br>
What is the distinction/interaction between phylib and MII
support ?<br>
<br>
Are they independent ways of doing something similar ? Or do
they work together.<br>
<br>
To get MII working I need to provide/populate an mii_if_info
structure and supply register read/write routines.<br>
<br>
Since communicating with the PHY is MAC dependent shouldn't I
need to do the same for PHYLIB ?<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
As I understand it although PHY's are similar, and the same
PHY may be used on different NIC's<br>
Communications to the PHY typically go through the NIC.<br>
So my Network driver has to provide routines to read/write
the registers of the PHY, which phylib and the phy driver then use.<br>
