Subject: [PATCH v3 1/7] e1000e: fix S0ix flow to allow S0i3.2 subset entry
Date: Fri,  4 Dec 2020 14:09:14 -0600	[thread overview]
Message-ID: <20201204200920.133780-2-mario.limonciello@dell.com> (raw)
In-Reply-To: <20201204200920.133780-1-mario.limonciello@dell.com>

From: Vitaly Lifshits <vitaly.lifshits@intel.com>

Changed a configuration in the flows to align with
architecture requirements to achieve S0i3.2 substate.

Also fixed a typo in the previous commit 632fbd5eb5b0
("e1000e: fix S0ix flows for cable connected case").
