From c45698f89626177f8c51409142cbe9c5bbed4af7 Mon Sep 17 00:00:00 2001 From: Marcelo Ricardo Leitner Date: Thu, 26 Apr 2018 16:58:50 -0300 Subject: [PATCH] sctp: remove old and unused SCTP_MIN_PMTU This value is not used anywhere in the code. In essence it is a duplicate of SCTP_DEFAULT_MINSEGMENT, which is used by the stack. SCTP_MIN_PMTU value makes more sense, but we should not change to it now as it would risk breaking applications. So this patch removes SCTP_MIN_PMTU and adjust the comment above it. Signed-off-by: Marcelo Ricardo Leitner Signed-off-by: David S.
