[E1000-devel] micro sec delay in transmission

[Sarbeswar M. <smo...@ip...>]

Hi All,

I am very new to linux kernel and driver world. I am trying to write a
module in the kernel which can transmit packets in 5, 10, 20.etc. micro
second interval. What I see, the packets are transmitted in 1 or 0 micro
second interval. I am using udelay before calling hard_stat_xmit function.
Also I saw that e1000 driver takes TxIntDelay and TxAbsIntDelay as module
parameters, I set to 5 (the transmit interrupt should be generated in
5x1.0124 micro second), but this does not seem to work either. Could any one
please  advise me what can I do to achieve this. But if I call
hard_start_xmit with more than 100 micro second then it works.

Regards,

Sarbeswar
