[PATCH v2 0/7] net/bnxt: Tx coalescing, function error recovery and Rx fixes

[Mohammad Shuab Siddique]

From: Mohammad Shuab Siddique <mohammad-shuab.siddique at broadcom.com>

This series is based on dpdk-next-net-brcm for-next-net.

Patch 1 enables Tx completion coalescing in hardware on P7 devices.
Patch 2 adds recovery from the function error state.
Patch 3 fixes an Rx stall caused by doorbell and vector Rx issues.
Patches 4-6 stop the AVX2 Rx burst functions from reading and writing
past the end of the completion ring and the caller's array.
Patch 7 fixes an Rx throughput drop on Thor2 with 256 byte packets.

v2:
* Patch 3: declare the Rx burst size variable as uint16_t instead of
  uint32_t in the vector Rx burst functions. It holds a value clamped
  to uint16_t, matching the rest of the driver.
* Patch 5: remove a duplicated comment line.
* Patches 5 and 6 are adjusted to match the type change in patch 3;
  the resulting code is unchanged.
* No other changes.
