Subject: gre: introduce 'nohostroute' option
X-Git-Tag: v19.07.0-rc1~550
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0f8b9addfc4fd59a488f64289aadd82c127f00e6;p=oweals%2Fopenwrt.git

gre: introduce 'nohostroute' option

It is not always necessary to add a host route for the gre peer address.

This introduces a new config option 'nohostroute' (similar to the
option introduced for wireguard in d8e2e19) to allow to disable
the creation of those routes explicitely.
