The network stack takes time.... question about where to look if i want to write direct to a driver.
I have a setup where i trying to send a packet over one ethernet port from an external interrupt.
But io-pkt takes lot of time when my interrupt is faster and faster.
So I thinking about bypassing the stack because it only take too much time. And it hopefully be faster if make the DMA
direct from my program.
I know that i need to setup the driver and other things before i can send, but this is all in the driver devnp-mpc85xx.
If i want to program this where can i look in io-pkt so understand how to do this and send packages to a driver directly
In my task a stack is not necessary, because i will send one package receive is calculate and send a new package.
Package on the Ethernet port is always from myself.
