From 3190b649b4d9391be7bde3edd8e924e451c5d2f6 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Tue, 22 Jun 2021 14:04:49 -0400 Subject: sctp: add SCTP_PLPMTUD_PROBE_INTERVAL sockopt for sock/asoc/transport With this socket option, users can change probe_interval for a transport, asoc or sock after it's created. Note that if the change is for an asoc, also apply the change to each transport in this asoc. Signed-off-by: Xin Long Acked-by: Marcelo Ricardo Leitner Signed-off-by: David S.
