3rd ed. files:

ether8139.bundle

Mar 7 patch

This bundle contains 3 files:
	README			- this file
	ether8139.c.kernel	- copy to /sys/src/9/pc
	ether8139.c.9load	- copy to /sys/src/boot/pc

To add to the kernel:
	1) do the above copy;
	2) edit whatever configuration file you use to add
		ether8139	pci
	   in the 'link' section;
	3) mk

To add to 9load:
  	1) do the above copy;
        2) in /sys/src/boot/pc/load.c after
                { "AMD79C970", amd79c970reset, },
           add
                { "RTL8139", rtl8139pnp, },
           and after
 		 extern int amd79c970reset(Ether*);
           add
                extern int rtl8139pnp(Ether*);
        3) in /sys/src/boot/pc/mkfile after
                ether8003.$O\
           add
                ether8139.$O\
        4) mk


The 'type' of the interface for plan9.ini is 'rtl8139', e.g.
	ether0=type=rtl8139

The driver will handle RTL8139 chips which have had the PCI Vendor
and Device ID changed, e.g. the SMC EZ-Card. There is a table in the
driver containing (VendorID<<16)|DeviceID to match against. E.g. the
generic Realtek value is (0x8139<<16)|0x10EC and the SMC EZ-Card is
(0x1211<<16)|0x1113.
It is possible to tell the driver to match against a new card not in
the table by supplying the PCI ID in a plan9.ini option, e.g.
	ether0=type=rtl8139 id=0x813910EC
If you come across such a card, please let us know so it can be added
to the internal driver table.
