The commit 414b202343ce8ad (bonding: fix initial link status of slave) invokes lsc callback,
the lsc callback may be executed at same time when slave_configure() and bond_ethdev_slave_link_status_change_monitor ()
competing for calling the lsc callback. The panic will be triggered when bond ethdev is started(bonding mode 4).
I think the lsc callback need lock to be protected. My dpdk version is dpdk-16.04.
