Hi,

I did this. Interrupt Status Register's bit 5 ( PUN/LinkChg- Packet 
Underrun/Link Change ) was getting set each time after a packet was sent 
through the RealTek 8139 NIC.

The status printed showed this (0x20 or 0x24),
diag_printf("rltk8139_deliver(%s): %04x\n", sc->dev_name, status);

Please let me know why this is happening? Is this a common thing or an error 
condition. Apart from the spec.Â’s (which gives very little details about 
these registers & the 8139 chip operation), is there a better document (or a 
detailed document for some other related chip)? If so, please send me the 
URL for the same.

Thanks,
-Mike.
