From e5b13ac0c46e4a8bf5e1bdf6317a6b1d4a5ad571 Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Wed, 7 Jul 2021 16:15:30 +0800 Subject: [PATCH] selftests: icmp_redirect: IPv6 PMTU info should be cleared after redirect After redirecting, it's already a new path. So the old PMTU info should be cleared. The IPv6 test "mtu exception plus redirect" should only has redirect info without old PMTU. The IPv4 test can not be changed because of legacy.
