Subject: isisd: Fix run level for spf_run_count
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=46a6060da2d649063ff8695791d56a1ba64178e9;p=mirror%2Ffrr.git

isisd: Fix run level for spf_run_count

Running isis with undefined behavior compiled in gives you this
warning:

isisd/isis_spf.c:2126:22: runtime error: index 2 out of bounds for type '_uint64_t [2]'

Looking at the rest of isis this should be level-1 because the
declaration for spf_run_count only has 2 levels.
