Subject: net: add net available in build_state
Patch-mainline: v5.7-rc1
Git-commit: faee676944dab731c9b2b91cf86c769d291a2237
References: bsc#1176447
The build_state callback of lwtunnel doesn't contain the net namespace
structure yet. This patch will add it so we can check on specific
address configuration at creation time of rpl source routes.
