Subject: [v3, net-next 00/12] bng_en: enhancements for link, Rx/Tx, LRO/TPA & stats

Hi,

This series enhances the bng_en driver by adding:
1. Link query support
2. Tx support (standard + TSO)
3. Rx support (standard + LRO/TPA)
4. ethtool link set/get functionality
5. Hardware statistics reporting via ethtool S

Changes from:
v2->v3
 Addressed comments from Andrew Lunn
   - Apply Rev-xmas fix in several places.
   - Correct ethtool-speed comment to reflect accurate behavior.

 Addressed comments from ALOK TIWARI
   - Remove duplicate definition of RX_CMP_L2_ERRORS.
   - Fix macro by adding the required arguments.
   - Add newline for clarity/formatting.

 Addressed kernel test robot warning
   - Fix compilation error: removed unused variable gro

 Moved hw specific structs to appropriate header file

v1->v2
 Removed unused function bnge_alloc_rx_page()
 Removed inline keywords from couple of functions
 Removed some stats related code that doesn't applicable (missed_irqs)
 Addressed kernel test robot warning
    - Fixed compilation issue with CONFIG_INET is not set

Bhargava Marreddy (12):
  bng_en: Query PHY and report link status
  bng_en: Extend bnge_set_ring_params() for rx-copybreak
  bng_en: Add RX support
  bng_en: Handle an HWRM completion request
  bng_en: Add TX support
  bng_en: Add support to handle AGG events
  bng_en: Add TPA related functions
  bng_en: Add support for TPA events
  bng_en: Add ethtool link settings and capabilities support
  bng_en: Add initial support for ethtool stats display
  bng_en: Create per-PF workqueue and timer for asynchronous events
  bng_en: Query firmware for statistics and accumulate
