Subject: [PATCH v3 net-next 2/7] net: ethernet: update drivers to handle HWTSTAMP_FILTER_NTP_ALL

Include HWTSTAMP_FILTER_NTP_ALL in net_hwtstamp_validate() as a valid
filter and update drivers which can timestamp all packets, or which
explicitly list unsupported filters instead of using a default case, to
handle the filter.
