Which functions did you have in mind?
The extack was added to XFRM .xdo_dev_state_add() call, which is
translated to bond_ipsec_add_sa() with only one slave_warn() print.
If you are talking about bond_ipsec_add_sa_all(), that function isn't
directly connected to netlink and doesn't have extack pointer to fill.
If you are talking about bond_ipsec_del_sai*() and slave_warn() there, it
will be better to be deleted/changed to make sure what ipsec_list have
only valid devices.
