Subject: net: switchdev: add SET_SWITCHDEV_OPS helper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d643a75ac2bcc559994405d29c50ed086aeae434;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: switchdev: add SET_SWITCHDEV_OPS helper

Add a helper to allow switchdev ops to be set if NET_SWITCHDEV is configured
and do nothing otherwise. This allows for slightly cleaner code which
uses switchdev but does not select NET_SWITCHDEV.
