Hello,
I tried to modify the 3c59x.c driver some time ago, unsuccessfully. I now want
to get around those difficulties, could you help?
My goal is to add an unsigned long value in all UDP packets received on a
particular port. This value represents the current time from a custom rtc timer
(8192Hz). I also modified ip_input.c and udp.c for the same purpose. Obviously,
I had to turn off the checksum in 3c59x.c and udp.c.
The problem is that I don't know where skbuff.{data, mac.ethernet} point to in
3c59x.c (or any driver, for what it matters)? As a result, the value is
probably copied in the wrong place.
Thanks,
Guilhem.
