Subject: [PATCH net-next v5 0/5] Introduce NETIF_F_GRO_HW

Introduce NETIF_F_GRO_HW feature flag and convert drivers that support
hardware GRO to use the new flag.

v5:
- Documentation changes requested by Alexander Duyck.
- bnx2x changes requested by Manish Chopra to enable LRO by default, and
disable GRO_HW if disable_tpa module parameter is set.

v4:
- more changes requested by Alexander Duyck:
- check GRO_HW/GRO dependency in drivers's ndo_fix_features().
- Reverse the order of RXCSUM and GRO_HW dependency check in
netdev_fix_features().
- No propagation in netdev_disable_gro_hw().

v3:
- Let driver's ndo_fix_features() disable NETIF_F_LRO when NETIF_F_GRO_HW
is set instead of doing it in common netdev_fix_features().

v2:
- NETIF_F_GRO_HW flag propagation between upper and lower devices not
required (see patch 1).
- NETIF_F_GRO_HW depends on NETIF_F_GRO and NETIF_F_RXCSUM.
- Add dev_disable_gro_hw() to disable GRO_HW for generic XDP.
- Use ndo_fix_features() on all 3 drivers to drop GRO_HW when it is not
supported

Michael Chan (5):
  net: Introduce NETIF_F_GRO_HW.
  net: Disable GRO_HW when generic XDP is installed on a device.
  bnxt_en: Use NETIF_F_GRO_HW.
  bnx2x: Use NETIF_F_GRO_HW.
  qede: Use NETIF_F_GRO_HW.
