[PATCH ethtool-next 1/2] ethtool: Update pause stats struct

[Mohsin Bashir <mohsin.bashr@gmail.com>]

With TX pause enabled, if a device is unable to pass packets up to the
stack (e.g., CPU is hanged), the device can cause pause storm. Given
that devices can have native support to protect the neighbor from such
flooding, such events need some tracking. This support is to track TX
pause storm events for better observability.

Kernel commit: 8d282b680c72 ("eth: fbnic: Fetch TX pause storm stats")

./ethtool -I -a eth0
Pause parameters for eth0:
Autonegotiate:	off
RX:		off
TX:		on
Statistics:
  tx_pause_frames: 1
  rx_pause_frames: 0
  tx_pause_storm_events: 0
