Subject: airoha: an7581: 6.18: switch to kmod-phy-realtek for w1700k
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=ecabaa534ed01b123dec42f2b89e5b62ff1494e2;p=thirdparty%2Fopenwrt.git

airoha: an7581: 6.18: switch to kmod-phy-realtek for w1700k

Use the new kmod-phy-realtek driver for kernel 6.18 on
Gemtek W1700K.

The driver selection is gated using `KERNEL_PATCHVER` to
avoid build failures on 6.12.

The device tree selection is also gated by `KERNEL_PATCHVER`
to select the appropriate device tree per kernel version.

Once kernel 6.18 is tested stable for airoha these changes
can be simplified and the obsolete properties removed.
