Konstantin Belousov 06193f0be0 Use hardware timestamps to report packet timestamps for SO_TIMESTAMP
and other similar socket options.

Provide new control message SCM_TIME_INFO to supply information about
timestamp.  Currently it indicates that the timestamp was
hardware-assisted and high-precision, for software timestamps the
message is not returned.  Reserved fields are added to ABI to report
additional info about it, it is expected that raw hardware clock value
might be useful for some applications.
