Subject: [PATCH v6 09/14] net: phy: add constants for fast retrain related register

From: Luo Jie <[email-masked]>
Date: Sat, 23 Oct 2021 17:54:48 +0800

Add the constants for 2.5G fast retrain capability
in 10G AN control register, fast retrain status and
control register and THP bypass register into mdio.h.
