net: ethtool: Update doc for tunable
ETHTOOL_PFC_PREVENTION_TOUT enables the configuration of timeout value
for PFC storm prevention. This can also be used to configure storm
detection timeout for global pause settings. In fact some existing
drivers are already using it for the said purpose.
Highlight that the knob can formally be used to configure timeout
value for pause storm prevention mechanism. The update to the ethtool
man page will follow afterwards.
