Does the kernel SCTP implementation have the implementation of RFC 4821
(Packetization Layer Path MTU Discovery) ? I am using 2.6.32-358.23.2
kernel, and did NOT find the implementation of RFC 4821 yet.
SCTP gets its mtu for outgoing paths from the ip layer (via dst_mtu). IIRC that
is 4821 compliant
No, ip layer mtu discovery is not 4821 compliant. SCTP does not
implement PMTU probing from 4821. Only TCP in linux appears to support
that.
