Subject: net: phy: add phyid search in vendor specific space
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=9c6de508a6362a3ddd4067e90f07ae613f312aa4;p=oweals%2Fu-boot.git

net: phy: add phyid search in vendor specific space

There are devices accesible through mdio clause-45, such as
retimers, that do not have PMA or PCS blocks.
This patch adds MDIO_MMD_VEND1 on the list of device addresses
where phyid is searched. Previous order of devices was kept.
