Commit Message

Geliang Tang May 16, 2024, 1:13 a.m. UTC 
From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses netns helpers create_netns() and cleanup_netns() in
lwt_helpers.h instead of using the local function netns_create() and
netns_delete().

For using these helpers. network_helpers.h needs to be included in
lwt_helpers.h. Then '#include "network_helpers.h"' in lwt_redirect.c
and lwt_reroute.c can be dropped.
