Subject: [PATCH net-next v5 0/2] qed*: Add support for PTP

This patch series adds required changes for qed/qede drivers for
supporting the IEEE Precision Time Protocol (PTP).

Dave,
Please consider applying this series to "net-next".

Thanks,
Yuval

Changes from previous versions:
-------------------------------
v5: Removed two divisions from the adjust-frequency loop.
    Resulting logic would use 8 divisions [instead of 24].

v4: Remove the loop iteration for value '0' in the qed_ptp_hw_adjfreq()
    implementation.

v3: Use div_s64 for 64-bit divisions as do_div gives error for signed
    types.
    Incorporated review comments from Richard Cochran.
      - Clear timestamp resgisters as soon as timestamp is read.
      - Use shift operation in the place of 'divide by 16'.

v2: Use do_div for 64-bit divisions.

  qed: Add infrastructure for PTP support
  qede: Add driver support for PTP
