Subject: lldpd: freeze execution of lldpd during reload
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=b7fadb12b76a471d66dfd3266ad0af2177914057;p=librecmc%2Flibrecmc.git

lldpd: freeze execution of lldpd during reload

During reload, we could send invalid information to the other
side and confuse it.

That's why, during reload we'll pause execution, do the reconfig
and resume + update when reload is done.
