Not as a limit of the mbuf chain code, but as a limit of the IP packet input code. Look at the description of the ip_maxfragpackets sysctl value in src/sys/netinet/ip_input.c It is initialized by default to (nmbclusters / 4) in ip_init(). The relevant code, that enforces the limit, is near the beginning of the ip_reass() function in the same file. Giorgos.
