I agree.
If networking maintainers are interested, I surely can prepare a patch.

But IMO some way to force TSC usage on x86_64 will be even better.

It would better describe what your patch is actually doing : Even if a tcpdump 
is running (so asking for timestamps), it wont have them because the sysctl 
disabled them.

Well, tcpdump will have timestamps, but taken at wrong moment.
But some other applications (that use ip_queue, ulog etc.) will not,
as I understand.

Thank you
