Subject: mptcp: pm: change rem type of set_flags
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=ab5723599cfd00a1898b11c9d67a770384a7f51b;p=users%2Fjedix%2Flinux-maple.git

mptcp: pm: change rem type of set_flags

Generally, in the path manager interfaces, the local address is defined
as an mptcp_pm_addr_entry type address, while the remote address is
defined as an mptcp_addr_info type one:

    (struct mptcp_pm_addr_entry *local, struct mptcp_addr_info *remote)

But the set_flags() interface uses two mptcp_pm_addr_entry type
parameters.

This patch changes the second one to mptcp_addr_info type and use helper
mptcp_pm_parse_addr() to parse it instead of using mptcp_pm_parse_entry().
