/*
 * The "legacy" flag indicates that the packet is a legacy dump
 * request message.
 *
 * Some legacy tools, including iproute2 < 3.9, issue shorter RTM_GETLINK
 * and RTM_GETADDR dump queries which only contain struct rtgenmsg rather
 * than struct ifinfomsg. As noted in kernel comment in rtnl_dump_ifinfo(),
 * these legacy requests will be (even with attributes) always shorter than
 * struct ifinfomsg so that they are easy to detect.
 *
 * Similar problem can be observed with tools using nl_rtgen_request()
 * function from libnl3; this also affects other RTM_GET* types.
 *
 * If such legacy message is detected by length shorter than expected data
 * structure, we parse it as this legacy version with (1-byte) struct
 * rtgenmsg so that it's shown as intended rather than as malformed.
 *
 * The legacy messages appear, from looking at the iproute2 3.1.0 code,
 * to be a structure containing a struct nlmsghdr followed by a struct
 * rtgenmsg.
 *
 * struct rtgenmsg contains only a 1-byte address family value, as noted.
 * *However*, a struct nlmsghdr has a 4-byte length field, and is, as a
 * result, aligned on a 4-byte boundary, so the structure containing those
 * two structures is also aligned on a 4-byte boundary, and thus has a
 * length that's a multiple of 4 bytes.  Therefore, there are 3 bytes of
 * padding following the address family byte.
 *
 * The message length, however, doesn't include those bytes.
 *
 * Legacy messages don't include any attributes - they're not large enough
 * to contain anything other than the netlink message header and the one-byte
 * address family.  For legacy messages, the attribute we hand to
 * dissect_netlink_route_attributes() is not aligned on a 4-byte boundary,
 * as it's the offset right after the 1-byte address family value;
 * dissect_netlink_route_attributes() will try to align that on a 4-byte
 * boundary, but that will go past the "immediately after the end of
 * the packet" offset, which can cause problems if any checking is done
 * to make sure the offset is valid.  Therefore, we don't try to dissect
 * the attributes, rather than relying on the attributes dissector to
 * discover that there's nothing left in the packet.
