Update FRR to 7.4 stable
As far as I understand it that option in Jenkins
But we also have some patches.
Not sure if it's relevant or not, but I think 7.5 was released....we might be able to just leapfrog 7.4 and go directly to 7.5 instead.
Neet to retest, the related task T2100
Sure, no worries. We still have a *ton* of work on 7.3.1 to do so I'm sure we'll get to 7.5 in time :)
