Then I should be fine, as my original code read:
*(((unsigned int *) (skb->data+20)) + 1)
I was under the assumption that int was 16 bits on x86, but Rene corrected me
("int = 32Bit @ linux"). I will test the code modified with u16 first thing in
the morning tomorrow. In all cases, the "+1" above refers to a pointer of
unsigned int, then alignment should be OK, right?
Thanks for the input. I hope not to bother anyone with that after tomorrow. :)
As a last resort, I will add some heuristic to find the port number in the
packet and start from there.
