754 | The encoding of the IFLA_AF_SPEC attribute varies depending on the family | |
755 | used for the request (RTM_GETLINK) message. For AF_UNSPEC the encoding | |
756 | has another level of nesting for each address family with the type encoded | |
757 | first. i.e., | |
758 | af_spec = nla_nest_start(skb, IFLA_AF_SPEC) | |
759 | for each family: | |
760 | af = nla_nest_start(skb, af_ops->family) | |

762 | nest_end | |

765 | This allows the parser to find the address family by looking at the first | |
766 | type. | |
767 | ||
768 | Whereas AF_BRIDGE encoding is just: | |
769 | af_spec = nla_nest_start(skb, IFLA_AF_SPEC) | |
770 | br_fill_ifvlaninfo{_compressed}(skb, vg) | |
771 | nest_end | |
