Here, should the comment on match_plens be something more like
"Prefixes that could possible match."?
struct trie_ctx {
const struct cls_trie *trie;
bool lookup_done; /* Status of the lookup. */
uint8_t be32ofs; /* U32 offset of the field in question. */
- unsigned int match_plen; /* Longest prefix than could possibly match. */
unsigned int maskbits; /* Prefix length needed to avoid false matches. */
+ union mf_value match_plens; /* Longest prefix than could possibly match. */
};
