Subject: devlink: Add IPv6 header for dpipe
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1797f5b3cf0b3a73c42b89f7a8fd897417373730;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

devlink: Add IPv6 header for dpipe

This will be used by the IPv6 host table which will be introduced in the
following patches. The fields in the header are added per-use. This header
is global and can be reused by many drivers.
