====================
net: ethtool: Track TX pause storm

With TX pause enabled, if a device cannot deliver received frames to
the stack (e.g., during a system hang), it may generate excessive pause
frames causing a pause storm. This series updates the uAPI to track TX
pause storm events as part of the pause stats (p1), proposes using the
existing pfc-prevention-tout knob to configure the storm watchdog (p2),
adds pause storm protection support for fbnic (p3), and leverages p1
to provide observability into these events for the fbnic (p4) and mlx5
(p5) drivers.
