From: Russell King (Oracle) Date: Wed, 1 Apr 2026 07:21:14 +0000 (+0100) Subject: net: stmmac: fix channel TSO enable on resume X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=989a9c20f63e378e0bb8b05bf82560d7da945de4;p=thirdparty%2Flinux.git net: stmmac: fix channel TSO enable on resume Rather than configuring the channels depending on whether GSO/TSO is currently enabled by the user, always enable if the hardware has TSO support and the platform wants TSO to be enabled. This avoids the channel TSO enable bit being disabled after a resume when the user has disabled TSO features. This will cause problems when the user re-enables TSO.
