Since the information whether the adaptive behavior is implemented
by DIM or driver custom is useful, so add new attribute to
ETHTOOL_MSG_COALESCE_GET/ETHTOOL_MSG_COALESCE_SET commands to control
the type of adaptive coalescing.
In order to compatible with ioctl code, add a extended coalescing
handler to deal with it in the netlink API, then other new extended
coalescing parameters can utiliaze it as well.
