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)
