Subject: [PATCH net-next 0/5] bnxt_en: Add RTC mode for PTP

This series adds Real Time Clock (RTC) mode for PTP timestamping.  In
RTC mode, the 64-bit time value is programmed into the NIC's PTP
hardware clock (PHC).  Prior to this, the PHC is running as a free
counter.  For example, in multi-function environment, we need to run
PTP in RTC mode.

Michael Chan (1):
  bnxt_en: Update firmware interface to 1.10.2.73

Pavan Chebbi (4):
  bnxt_en: PTP: Refactor PTP initialization functions
  bnxt_en: Add driver support to use Real Time Counter for PTP
  bnxt_en: Implement .adjtime() for PTP RTC mode
  bnxt_en: Handle async event when the PHC is updated in RTC mode
