Subject: ripd: move global counters to the rip structure
X-Git-Tag: 7.1_pulled~99^2~27
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=c08a21077faa595a76f87cc4b67d76623f045e0f;p=matthieu%2Ffrr.git

ripd: move global counters to the rip structure

The only sideeffect of this change is that these counters will be
reset when RIP is deconfigured and then configured again, but this
shouldn't be a problem as the RIP MIB isn't specific about this.
