The maximum size in bytes of a Medium PPP packet.
This value specifies the threshold at which Multilink
fragmentation is applied to transmitted packets, i.e.
packets smaller than this size will be encapsulated in
a single Multilink Protocol fragment and sent on a single
link, packets larger than this size will be fragmented
over all links in the bundle.
Medium PPP packets are defined to be those which will be
encapsulated in a single Multilink Protocol Fragment
and sent on each link in the Bundle in a round-robin
fashion.
Packets larger than this threshold are considered Large
PPP packets. Large PPP packets will be fragmented into
multiple Multilink Protocol Fragments and sent across
all links in the bundle.
Setting this value to its maximum (65535) will prevent
fragmentation at the MP layer of outgoing PPP packets,
i.e. it will cause all outgoing PPP packets to be
considered either Small or Medium sized PPP packets.
Note that this parameter only applies to outgoing PPP
packets sent by this system. Reassembly of incoming
packets is unaffected by this value.
