Hi all,
I am developing a ethernet driver in QNX. I followed the PCNET code given
with ddk.
The MII handling code…(using MDI library functions) is exactly same as the
pcnet driver.

I noticed that MDI -Timer Interrupt continuosly coming after i mount my
driver.
Is it a Normal behaviour… ??
Couldnt find any info regarding MDI in QNX!!!

My transmit… and receive functions …yet not functioning…
any help!!!

Yes - it is checking the status of the MDI interface. This is normal.
