Subject: [IPSEC]: Rename tunnel-mode functions to avoid collisions with tunnels
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=195ad6a3ac8b5c4eef4916efcb673e96e6f09d89;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[IPSEC]: Rename tunnel-mode functions to avoid collisions with tunnels

It appears that I've managed to create two different functions both
called xfrm6_tunnel_output.  This is because we have the plain tunnel
encapsulation named xfrmX_tunnel as well as the tunnel-mode encapsulation
which lives in the files xfrmX_mode_tunnel.c.

This patch renames functions from the latter to use the xfrmX_mode_tunnel
prefix to avoid name-space conflicts.
