I am trying to understand the vortex driver.
I believe that I am not looking at the correct documentation.

I read The following doc :

PCI/EISA Bus-Master Adaptater Driver Technical Reference Members of the 3Com EtherLink III and Fast Etherlink families of adapters Manual Part Number 09-0681-001B

The reason I believe there is a better doc is that the driver read info1 and info2 fields from the EEPROM and then does :

 if (vp->info1 & 0x8000) {
    vp->full_duplex = 1;
    if (print_info)
       printk(KERN_INFO "Full duplex capable\n");

}

...

if (print_info) {
printk(KERN_INFO " Enabling bus-master transmits and %s receives.\n",
(vp->info2 & 1) ? "early" : "whole-frame" );
}

But in my doc both these bits are marked 'reserved'.

I understand that these bits could be defined in more recent chipset but in the doc I am looking at the full duplex capability is defined in another field in the EEPROM:

Capabilities Word (offset 0x10) : supportsFullDuplex bit (bit 1)
