Subject: [PATCH net v3 0/2] mlx5: ptp fifo bugfixes

From: Vadim Fedorenko <vfedorenko@...a.com>

Simple FIFO implementation for PTP queue has several bugs which lead to
use-after-free and skb leaks. This series fixes the issues and adds new
checks for this FIFO implementation to uncover the same problems in
future.

v2 -> v3:
  Rearrange patches order and rephrase commit messages
  Remove counters as Gal confirmed FW bug, use KERN_ERR message instead
  Provide proper budget to napi_consume_skb as Jakub suggested
v1 -> v2:
  Update Fixes tag to proper commit.
  Change debug line to avoid double print of function name

Vadim Fedorenko (2):
  mlx5: fix skb leak while fifo resync and push
  mlx5: fix possible ptp queue fifo use-after-free
