I applied the patch (in revision 9e80af2) with the following commit message:

accept delayed rebroadcasts to avoid bogus routing under heavy load
    
When a link is saturated (re)broadcasts of OGMs are delayed. Under heavy load
this delay may exceed the orig interval which leads to OGMs being dropped (the
code would only accept an OGM rebroadcast if it arrived before the next OGM 
was broadcasted). With this patch batman-adv will also accept delayed OGMs in 
order to avoid a bogus influence on the routing metric.

Thanks,
Marek
