/* * FreeBSD 4.6 introduced m_getcl(), which performs `fast' allocation * mbuf clusters from a cache of recently-freed clusters. (If the cache * is empty, new clusters are allocated en-masse). * On NetBSD, for now, implement the `cache' as a function * using normal NetBSD mbuf/cluster allocation macros. Replace this * with fast-cache code, if and when NetBSD implements one. */
