Subject: [PATCH net-next 2/2] stmmac: intel: Enable 2.5Gbps on Intel AlderLake-S
Date: Mon,  9 Aug 2021 18:22:29 +0800	[thread overview]
Message-ID: <20210809102229.933748-3-vee.khee.wong@linux.intel.com> (raw)
In-Reply-To: <20210809102229.933748-1-vee.khee.wong@linux.intel.com>

From: Michael Sit Wei Hong <michael.wei.hong.sit@intel.com>

Intel AlderLake-S platform is capable of 2.5Gbps link speed.

This patch enables the 2.5Gbps link speed by adding the callback
function in the AlderLake-S PCI info struct.
