[PATCH net-next 00/10] bnxt_en: PTP updates for net-next

The first 5 patches implement the PTP feature on the new BCM5760X
chips.  The main new hardware feature is the new TX timestamp
completion which enables the driver to retrieve the TX timestamp
in NAPI without deferring to the PTP worker.

The last 5 patches increase the number of TX PTP packets in-flight
from 1 to 4 on the older BCM5750X chips.  On these older chips, we
need to call firmware in the PTP worker to retrieve the timestamp.
We use an arry to keep track of the in-flight TX PTP packets.

Michael Chan (4):
  bnxt_en: Add new TX timestamp completion definitions
  bnxt_en: Add is_ts_pkt field to struct bnxt_sw_tx_bd
  bnxt_en: Allow some TX packets to be unprocessed in NAPI
  bnxt_en: Add TX timestamp completion logic

Pavan Chebbi (6):
  bnxt_en: Add BCM5760X specific PHC registers mapping
  bnxt_en: Refactor all PTP TX timestamp fields into a struct
  bnxt_en: Remove an impossible condition check for PTP TX pending SKB
  bnxt_en: Let bnxt_stamp_tx_skb() return error code
  bnxt_en: Increase the max total outstanding PTP TX packets to 4
  bnxt_en: Remove atomic operations on ptp->tx_avail
