igb: add per-packet timestamping
This patch adds support for per-packet timestamping for the
82580 adapter. The rx timestamp code is also pulled out of the
inlined rx hotpath and instead moved to a seperate function.
This version adds a comment explaining the per-packet timestamping
code added to igb_hwtstamp_ioctl().
