> code
> 
> As implemented in igc_ethtool_get_ts_info(), igc only supports
> HWTSTAMP_
> FILTER_ALL so any HWTSTAMP_FILTER_* option the user may set falls back
> to
> HWTSTAMP_FILTER_ALL.
> 
> HWTSTAMP_FILTER_ALL is implemented via Rx Time Sync Control
> (TSYNCRXCTL)
> configuration which timestamps all incoming packets. Configuring an
> UDP filter, in addition to TSYNCRXCTL, doesn't add much so this patch
> removes that code. It also takes this opportunity to remove some
> non-applicable comments.
