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.
