    Subject[PATCH 5.18 120/339] bonding: show NS IPv6 targets in proc master info
    Date
    From: Hangbin Liu <liuhangbin@gmail.com>

    [ Upstream commit 4a1f14df55d1e9ecdfa797a87a80131207cbd66f ]

    When adding bond new parameter ns_targets. I forgot to print this
    in bond master proc info. After updating, the bond master info will look
    like:

    ARP IP target/s (n.n.n.n form): 192.168.1.254
    NS IPv6 target/s (XX::XX form): 2022::1, 2022::2

    Fixes: 4e24be018eb9 ("bonding: add new parameter ns_targets")
