Subject: [PATCH iwl-next v2 2/3] igc: move autoneg-enabled settings into igc_handle_autoneg_enabled()
Date: Thu, 16 Apr 2026 09:55:19 +0800	[thread overview]
Message-ID: <20260416015520.6090-3-khai.wen.tan@linux.intel.com> (raw)
In-Reply-To: <20260416015520.6090-1-khai.wen.tan@linux.intel.com>

From: Faizal Rahim <faizal.abdul.rahim@linux.intel.com>

Move the advertised link modes and flow control configuration from
igc_ethtool_set_link_ksettings() into igc_handle_autoneg_enabled().

No functional change.
