* INSTALLATION: *
--------------------------------------------------------------------------------
To install LAN8710A for BeagleBone under MINIX you have to edit /etc/inet.conf
by adding line:
eth0 lan8710a 0 { default; };
and changing:
psip0 { default; };
to:
psip1;
Restart the system and the driver should work.
To install LAN8710A for BeagleBone under MINIX you execute 'netconf' as
usual. Select the LAN8710A driver from the list. Restart the system
and the driver should work.
