SubjectBeginer's Q> arp_run_bh?
Hi, All.
I'm confusing about the relation between the timer and bh in case of
arp_update.

At the end of arp_update, there are
"arp_enqueue(&arp_backlog, entry);
arp_bh_mask |= ARP_BH_BACKLOG; ."
Do you know the purpuse of these two lines?
I suppose "arp_run_bh" do something with the enqued backlog,
but it follows different way from mark_bh() does.
Also timer does something( entry expiry? ) related with this, but how is
this set to be called?

Would you make it clear for me?

Thanks in advance,
-heejin
