Reg - Sample Ethernet driver   
Hi,

I  have download the sample ethernet driver and i mounted.

if i done ifconfig then  sam0 interface is  present.Here there is no hardware interrupt.
Interrupt is getting from qtime for every sec/msec (i dont know).

What i did was gets the packets from ethernet interface and give it to stack via sam0 interface.

My test setup :

QNX PC 1: ifconfig en1 20.0.0.3 
QNX PC2 :ifconfig sam0 20.0.0.1

if i do ping - ping is working file .

But if i do ping -f 20.0.0.3. it sends only  1000 packets/sec.But other interfaces ping -f 172.30.14.80 it 7000 Packets/
sec.

I think Because of qtime interrupt.

Can you please suggest how to process all the ping packets.

Thanks and Regards
K.Senthil

You probably need to attach to the real interrupt.

Hi Sean,

is there any posibility to change the qtime value to process the interrupt quickly.


Thanks and Regards

The resolutoin of the timer tick can be changed
with ClockPeriod(); however doing so in this
case is wrong if your hardware has a real interrupt.

Hi Sean,

I dont have real interrupt because i m using that as a dummy interface, i will get the packet from ethernet interface.

Thanks and Regards
