Subject: [dpdk-dev] [PATCH v2 5/7] net/i40e/base: add EEE LPI status check for X722 adapters
Date: Sat, 12 Sep 2020 03:00:37 +0000
Message-ID: <20200912030039.55273-6-guinanx.sun@intel.com> (raw)
In-Reply-To: <20200912030039.55273-1-guinanx.sun@intel.com>

Add reading LPI (low power idle) status for supported X722 devices.
If adapter's PHY supports EEE in current mode (device ID + link speed),
LPI status is read from PHY Clause 45 PCS status register.
