[Etherboot-developers] eepro100 driver strange behaviour..

[atul s. <atu...@re...>]

I am trying to use etherboot for net booting using
82557 network card.

my driver is eepro100.c by R.E.wolff that is a scaled down version 
of donald becker one.
this driver doesn't uses any interrupt and packet reception is 
polling driven.

resource assignment for pci base addreses are:

BAR0 - 0x60000000
BAR1 - 0x18800001
BAR2 - 0x62000000

these addresses are as per the mips idt manual.
also virt_to_bus are confirmed to be o.k

i am able to correctly read MAC address for card.

also packet reception is o.k , so the pci bus to memory trasaction 
is taking place.

my problem is in packet trasmission i should get txfd.status to 
become  nonzero for indicating packet trasfer has happened but it 
never happens and my driver hangs there for ever.

when debugged i saw from very begining status as 0090
.

as per eepro manual status 0090 indicates "NO RESOURCE"

but i am unable to conclude what it means..

can any body help..?

Best Regards,
