Subject: net/dst: add new function skb_dst_update_pmtu_no_confirm
From: Hangbin Liu <liuhangbin@xxxxxxxxx>
[ Upstream commit 07dc35c6e3cc3c001915d05f5bf21f80a39a0970 ]
Add a new function skb_dst_update_pmtu_no_confirm() for callers who need
update pmtu but should not do neighbor confirm.
v5: No change.
v4: No change.
v3: Do not remove dst_confirm_neigh, but add a new bool parameter in
dst_ops.update_pmtu to control whether we should do neighbor confirm.
Also split the big patch to small ones for each area.
v2: Remove dst_confirm_neigh in __ip6_rt_update_pmtu.
