	i82586.c 
Log Message:
Provide an alternative method of transmitting frames that avoids sending
a command to the 82586 for every frame to be transmitted. Instead, a
single command sets off the execution of a chain of commands consisting
of alternate XMITs and NO-OPs, where the link fields in the NO-OPs are
set to loop back onto themselves until the next XMIT is ready to go.
This trick found on a Linux WEB page.

All this induces reasonable transmission performance in my old multibus
adapter. The receiver performance is still abysmal..
