doc/research: Describe all kern.ipc.* sysctl's that lack a description

completed by: Taras Klaskovsky

mentors: Samuel J. Greear

The kern.ipc.* sysctl's that lack a description are as follows:

kern.ipc.sockbuf_waste_factor:
kern.ipc.max_linkhdr:
kern.ipc.max_protohdr:
kern.ipc.max_hdr:
kern.ipc.max_datalen:
kern.ipc.mbstat:
kern.ipc.msgseg:
kern.ipc.msgssz:
kern.ipc.msgtql:
kern.ipc.msgmnb:
kern.ipc.msgmni:
kern.ipc.msgmax:
kern.ipc.semaem:
kern.ipc.semvmx:
kern.ipc.semusz:
kern.ipc.semume:
kern.ipc.semopm:
kern.ipc.semmsl:
kern.ipc.semmnu:
kern.ipc.semmns:
kern.ipc.semmni:
kern.ipc.semmap:
kern.ipc.shm_use_phys:
kern.ipc.shmall:
kern.ipc.shmseg:
kern.ipc.shmmni:
kern.ipc.shmmin:
kern.ipc.shmmax:
kern.ipc.m_defragfailure:
kern.ipc.m_defraguseless:
kern.ipc.m_defragbytes:
kern.ipc.m_defragpackets:
kern.ipc.mbtypes:
kern.ipc.mbuf_wait:

Research these sysctl's in the kernel code and document each with a descriptive but concise sentence (approximately 3-15 words).

 

Deliverables: A description of each sysctl listed above.

Bonus deliverables: The above descriptions in the form of a kernel patch
