Add timestamping information as provided by ETHTOOL_GET_TS_INFO ioctl
command in GET_INFO reply if ETH_INFO_IM_TSINFO flag is set in the request.
Add constants for counts of HWTSTAMP_TX_* and HWTSTAM_FILTER_* constants
and provide symbolic names for timestamping related values so that they can
be retrieved in GET_STRSET and GET_INFO requests.
