Julian Elischer 167aa83312 Add the driver for "myson" ethernet cards. 
This driver was written by Myson and is made available
by their courtesy.
The 5.x version is not fully tested (I will be testing) but
the 4.x version has been tested by many.
I will commit it soon.
Myson have their own chip design based on the DEC 214xx family but
with several differences. Myson sells this chip to several
EOMs in teh Chinese area so there may be many noname brand cards
that respond to this driver. Myson will be supplying a list
of some of these.

* A transmit 'super descriptor' is actually MY_MAXFRAGS regular

* multi-fragment descriptor layout found in devices such as the
* Texas Instruments ThunderLAN and 3Com boomerang and cylone chips.
* The advantage to using this scheme is that it avoids buffer copies.
* The disadvantage is that there's a certain amount of overhead due
* to the fact that each 'fragment' is 16 bytes long. In my tests,
* this limits top speed to about 10.5MB/sec. It should be more like
* 11.5MB/sec. However, the upshot is that you can achieve better
* results on slower machines: a Pentium 200 can pump out packets at
* same speed as a PII 400.

/*
* RESET: 1 == software reset, 0 == normal operation
* Resets status and control registers to default values.
* Relatches all hardware config values.
*
* LOOPBK: 1 == loopback operation enabled, 0 == normal operation
*
* SPEEDSEL: 1 == 100Mb/s, 0 == 10Mb/s
* Link speed is selected byt his bit or if auto-negotiation if bit
* 12 (AUTONEGENBL) is set (in which case the value of this register
* is ignored).
*
* AUTONEGENBL: 1 == Autonegotiation enabled, 0 == Autonegotiation disabled
* Bits 8 and 13 are ignored when autoneg is set, otherwise bits 8 and 13
* determine speed and mode. Should be cleared and then set if PHY configured
* for no autoneg on startup.
*
* ISOLATE: 1 == isolate PHY from MII, 0 == normal operation
*
* AUTONEGRSTR: 1 == restart autonegotiation, 0 = normal operation
*
* DUPLEX: 1 == full duplex mode, 0 == half duplex mode
*
* COLLTEST: 1 == collision test enabled, 0 == normal operation
