Subject: ipv6: Export ipv6 functions for use by other protocols
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a495f8364efe11f4813914b09cf0d026364d6969;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ipv6: Export ipv6 functions for use by other protocols

For implementing other protocols on top of IPv6, such as L2TPv3's IP
encapsulation over ipv6, we'd like to call some IPv6 functions which
are not currently exported. This patch exports them.
