SubjectRe: hires timestamps for netif_rx()

The discreprency is that get_fast_time() returns the current value of
xtime, while do_gettimeofday() may actually calculate the time and
consider both xtime and the jiffies.

Look at the x86 implementation of do_fast_time, it equals
do_gettimeofday() when TSC is present which is the only time
that do_gettimeofday is going to be more accurate than xtime.

Franks a lot,
