Add PTP RX and TX hardware timestamp support on 575XX devices.  These
devices use the two-step method to implement the IEEE-1588 timestamping
support.

Michael Chan (4):
  bnxt_en: Update firmware interface to 1.10.2.34.
  bnxt_en: Get PTP hardware capability from firmware.
  bnxt_en: Add PTP clock APIs, ioctls, and ethtool methods.
  bnxt_en: Enable hardware PTP support.

Pavan Chebbi (3):
  bnxt_en: Get the full 48-bit hardware timestamp periodically.
  bnxt_en: Get the RX packet timestamp.
  bnxt_en: Transmit and retrieve packet timestamps.
