[PATCH] bonding: fix deadlock on high loads in bond_alb_monitor()
In bond_alb_monitor the bond->curr_slave_lock write lock is taken and then dev_set_promiscuity maybe called which can take some time, depending on the network HW. If a network IRQ for this card come in the softirq handler maybe try to deliver more packets which end up in a request to the read lock of bond->curr_slave_lock -> deadlock. This issue was found by a test lab during network stress tests, this patch disable the softirq handler for this case and solved the issue.
