The first patch fixes the incorrect locks using in bond driver.
The second patch fixes the xfrm offload feature during setup active-backup
mode. The third patch add a ipsec offload testing.

v5: use list_for_each_entry_safe() when del item in list (Nikolay Aleksandrov)
    do not call spin_lock_bh in sleep function xdo_dev_state_free (Nikolay Aleksandrov)
    set xso.real_dev = NULL to avoid __xfrm_state_delete() is called in parallel()  (Cosmin Ratiu)
    remove spin lock in bond_ipsec_add_sa_all() as it doesn't resolve the race condition.
v4: hold xs->lock for bond_ipsec_{del, add}_sa_all (Cosmin Ratiu)
    use the defer helpers in lib.sh for selftest (Petr Machata)
v3: move the ipsec deletion to bond_ipsec_free_sa (Cosmin Ratiu)
v2: do not turn carrier on if bond change link failed (Nikolay Aleksandrov)
    move the mutex lock to a work queue (Cosmin Ratiu)

    conditions
