SMSC 91C111 and PXA270

Hi,

I am using the driver provided by SMSC for the LAN91C111 ethernet
controller.

the settings are VLIO, 16 bit bus.

The driver is accessing all registers correctly accept for the interrupt
register, where it fails to acknoledge TX interrupt, and therefor stuck
forever trying to clear the TX bit.

When I am enabling KITL, VMINI is working OK with interrupts enabled.
The ethdrv is able to access the 91C111 when the bus is configured for 32
bit using OUTPORT16 and INPORT16 macros, but the ndis driver fails to
access with the same settings. I have to switch to 16 bit mode in order
for the ndis driver to be able to succeed even in a simple read/write
test.

1. Why is the difference?
2. Is someone had the same problem in reading interrupt status register?

Thx,
Lrz
