Subject: net: Make mpls_entry_encode() available for generic users
X-Git-Tag: baikal/mips/sdk5.9~13530^2~49^2~10
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=b6381d8f9b4d3abbdb05654a0cf87829a848edf1;p=kernel.git

net: Make mpls_entry_encode() available for generic users

Move mpls_entry_encode() from net/mpls/internal.h to include/net/mpls.h
and make it available for other users. Specifically, hardware driver that
offload MPLS can benefit from that.
