In miniflow_equal_maps(), if we believe that tnl_map is usually 0, then
it would be profitable to test pkt_map first to allow short-circuiting
to bail out earlier, e.g.:
static inline bool
miniflow_equal_maps(const struct miniflow *a, const struct miniflow *b)
{
return a->pkt_map == b->pkt_map && a->tnl_map == b->tnl_map;
}
Of course that's a super-micro-optimization.
