Subject: generic: remove support for older kernels from swconfig
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8181f09049a0e3188f35f27e5b53fc47b39eec87;p=openwrt%2Fstaging%2Fxback.git

generic: remove support for older kernels from swconfig

The legacy swconfig switch driver framework supports kernels older than
Linux 6.6 by using #ifdef'ery with LINUX_VERSION_CODE. Remove all that.
