Subject: [PATCH net 0/3] broadcom: report the supported flags for ancillary
 features

James Clark reported off list that the broadcom PHY PTP driver was
incorrectly handling PTP_EXTTS_REQUEST and PTP_PEROUT_REQUEST ioctls since
the conversion to the .supported_*_flags fields. This series fixes the
driver to correctly report its flags through the .supported_perout_flags
and .supported_extts_flags fields. It also contains an update to comment
the behavior of the PTP_STRICT_FLAGS being always enabled for
PTP_EXTTS_REQUEST2.

I plan to follow up this series with some improvements to the PTP
documentation better explaining each flag and the expectation of the driver
APIs.
