Hi
I am modifying the linux kernel to timestamp packets with the cycle counter
rather than using its current xtime-scheme. I am modifying it to work with a
program using the libpcap library. Anyways, I stamp my incoming packets at
the device driver level and I am wondering how far down in the kernel can I
stamp my outgoing packets and still be able to read the new values using the
pcap library, I tried the driver, but that was too far down. I am currently
doing it in dev_queue_xmit_nit in core.c but was trying to push it even
farther down. I was wondering if someone could tell me where pcap captures
them so I can read the counter right before that
Thanks
Adam
