Subject: IPoIB: Retry failed send-only multicast group joins
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c11bd42a7676b49d41c780f2ede3709204f8da83;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

IPoIB: Retry failed send-only multicast group joins

When a send-only multicast group join fails, mcast->query must be set
to NULL.  Otherwise, IPoIB will never retry the join and the multicast
group will never be reachable.
