I think the logic of the fix is fine, but theres a lot of duplication
here.
Why not make a:
struct bridge_mcast_timer {
struct timer_list timer;
u32 queries_sent;
u32 startup_queries_sent;
};
Then in the port structure you have:
struct bridge_mcast_timer ip4;
struct bridge_mcast_timer ip6;
And pass a reference to the right one into generic helper functions.
That sounds a lot better right?
Please make this improvement and resubmit, thanks.
