[B.A.T.M.A.N.] [PATCH v2 0/4] batctl: netlink support for DAT and MCAST

This patchset adds netlink support for dumping DAT cache and multicast flags tables.

Changes in v2: ==============

- Removed htonl() conversion for BATADV_ATTR_DC_ADDRESS as batman-adv now provides it in network byte order (via nla_put_in_addr() ) - Increased BATADV_ATTR_MCAST_FLAGS and BATADV_ATTR_MCAST_FLAGS_PRIV size from 8 to 32 bits to enhance extensibility - Changed mcast_flags error value from -EINVAL to -ENOTSUPP to allow a fallback to and retry via debugfs, for compatibility with older batman-adv versions
