Hi, We have an kernel app (or code which runs only in the kernel).
I dont want to use the networking code of the linux kernel.
I just want to call the linux network device driver functions from my code (say some character driver).
Actually, the driver is not a character driver in the true sense.
It actually sends and recieves network packets (Only Ethernet Packets) No TCP/IP.
But I think the ethernet driver is closely coupled with the networking code of linux.
I dont have any ethernet driver running on my system.
On my system only my driver will send and recieve packets (enet) over the network.
I tried modifying the enet code. but i dont know what the upper layer passes to each of the driver functions.
It passes some device and net_device structures and i dont know what values these contain when it passes to the lower driver layer and what modifications the upper layer do to these data structures.
I know the base address and irq
I am using smc91x.c linux driver.
I need your advice in this regard. how can i solve and resolve my problem and how do i go about it.
The reason why i want to do it is time. sending/recieving the packets must be very fast (very high performance sensitive).
