Subject: [v4, net-next 0/7] bng_en: enhancements for RX and TX datapath

Hi,

This series enhances the bng_en driver by adding:
1. Tx support (standard + TSO)
2. Rx support (standard + LRO/TPA)

Changes from:
v3->v4
 - Scoped the series to RX and TX datapath per Jakub Kicinski's comments.
 - Dropped IS_ERR() per Alok Tiwari's comments.

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
