Subject: [PATCH] net: phy: realtek: add 5Gbps support to rtl822x_config_aneg()
Git-commit: db1bb7741ff29bf2cefcbc0ca567644e9ed1caa9
Patch-mainline: v6.9-rc1
References: bsc#1217417
RTL8126 as an evolution of RTL8125 supports 5Gbps. rtl822x_config_aneg()
is used by the PHY driver for the integrated PHY, therefore add 5Gbps
support to it.
