Commit Message

Geliang Tang Nov. 28, 2023, 2:22 p.m. UTC 
Before freeing addresses in userspace_pm_local_addr_list(), RM_ADDRs for
the addresses should be sent and the subflows established with these
addresses should be deleted.

This patch invokes mptcp_pm_remove_addrs() and mptcp_pm_remove_subflows()
in mptcp_userspace_pm_free_local_addr_list() to remove the related
addresses and subflows.
