Subject: [PATCH net-next 00/23] bnxt_en: Add support for new 57500 chips.

This patch-set is larger than normal because I wanted a complete series
to add basic support for the new 57500 chips.  The new chips have the
following main differences compared to legacy chips:

1. Requires the PF driver to allocate DMA context memory as a backing
store.
2. New NQ (notification queue) for interrupt events.
3. One or more CP rings can be associated with an NQ.
4. 64-bit doorbells.

Most other structures and firmware APIs are compatible with legacy
devices with some exceptions.  For example, ring groups are no longer
used and RSS table format has changed.

The patch-set includes the usual firmware spec. update, some refactoring
and restructuring, and adding the new code to add basic support for the
new class of devices.

Michael Chan (23):
  bnxt_en: Update firmware interface spec. to 1.10.0.3.
  bnxt_en: Add additional extended port statistics.
  bnxt_en: Add maximum extended request length fw message support.
  bnxt_en: Update interrupt coalescing logic.
  bnxt_en: Refactor bnxt_ring_struct.
  bnxt_en: Add new flags to setup new page table PTE bits on newer
    devices.
  bnxt_en: Check context memory requirements from firmware.
  bnxt_en: Configure context memory on new devices.
  bnxt_en: Add 57500 new chip ID and basic structures.
  bnxt_en: Re-structure doorbells.
  bnxt_en: Adjust MSIX and ring groups for 57500 series chips.
  bnxt_en: Modify the ring reservation functions for 57500 series chips.
  bnxt_en: Allocate completion ring structures for 57500 series chips.
  bnxt_en: Add helper functions to get firmware CP ring ID.
  bnxt_en: Modify bnxt_ring_alloc_send_msg() to support 57500 chips.
  bnxt_en: Allocate/Free CP rings for 57500 series chips.
  bnxt_en: Increase RSS context array count and skip ring groups on
    57500 chips.
  bnxt_en: Add RSS support for 57500 chips.
  bnxt_en: Use bnxt_cp_ring_info struct pointer as parameter for RX
    path.
  bnxt_en: Add coalescing setup for 57500 chips.
  bnxt_en: Refactor bnxt_poll_work().
  bnxt_en: Add new NAPI poll function for 57500 chips.
  bnxt_en: Add PCI ID for BCM57508 device.
