From: Mohsin Bashir Date: Mon, 2 Mar 2026 23:01:46 +0000 (-0800) Subject: net: ethtool: Update doc for tunable X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=817de93c348a3086ecca6e03ff459138832157cc;p=thirdparty%2Fkernel%2Flinux.git 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.
