Subject: [PATCH] net/bonding: fix race condition
[ upstream commit 5922ff069fb910946f97780754ad4b66b987d5b6 ]
Race condition can appear in the bond_mode_8023ad_periodic_cb()
callback when bonding port is stopped, reconfigured and restarted.
Re-ordered calls in bond_ethdev_start() to have callback alarm set
after slave ports are reconfigured.
Fixes: 2efb58cbab6e ("bond: new link bonding library")
