From 22d7be267eaa8114dcc28d66c1c347f667d7878a Mon Sep 17 00:00:00 2001 From: Marcelo Ricardo Leitner Date: Thu, 26 Apr 2018 16:58:58 -0300 Subject: [PATCH] sctp: remove sctp_transport_pmtu_check We are now keeping the MTU information synced between asoc, transport and dst, which makes the check at sctp_packet_config() not needed anymore. As it was the sole caller to this function, lets remove it. Signed-off-by: Marcelo Ricardo Leitner Signed-off-by: David S.
