X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25e7f2de96588890536c4032b703e4568495b212;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git sctp: set the value of flowi6_oif to sk_bound_dev_if to make sctp_v6_get_dst to find the correct route entry. if there are several same route entries with different outgoing net device, application's socket specifies the oif through setsockopt with SO_BINDTODEVICE, sctpv6 should choose the route entry whose outgoing net device is the oif which was specified by socket, set the value of flowi6_oif to sk->sk_bound_dev_if to make sctp_v6_get_dst to find the correct route entry.
