X-Git-Tag: baikal/aarch64/sdk6.1~3836^2~39
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=cd7b33417902fe164b31688a3315914d520dbb12;p=kernel.git

net: lan743x: PCI11010 / PCI11414 fix

Fix the MDIO interface declarations to reflect what is currently supported by
the PCI11010 / PCI11414 devices (C22 for RGMII and C22_C45 for SGMII)
