255 *
256 * MAC_SW_CLASSIFIER

258 * The driver delivers traffic for multiple clients to this ring.
259 * All traffic must be software classified by MAC to guarantee
260 * delivery to the correct client. This classification type may
261 * be chosen for several reasons.
262 *
263 * o The driver provides only one group and there are multiple
264 * clients using the MAC.
265 *
266 * o The driver provides some hardware filtering but not enough
267 * to fully classify the traffic. E.g., a VLAN VNIC requires L2
268 * unicast address filtering as well as VLAN filtering, but
269 * some drivers may only support the former.
270 *
271 * o The ring belongs to the default group. The default group
272 * acts as a spillover for all clients that can't reserve an
273 * exclusive group. It also handles multicast traffic for all
274 * clients. For these reasons, the default group's rings are
275 * always software classified.
276 *
277 * MAC_HW_CLASSIFIER
278 *
279 * The driver delivers traffic for a single MAC client across
280 * this ring. With this guarantee, MAC can simply pass the
281 * traffic up the stack or even allow polling of the ring.
282 *
283 * MAC_PASSTHRU_CLASSIFIER
284 *
285 * The ring is in "passthru" mode. In this mode we bypass all of
286 * the typical MAC processing and pass the traffic directly to
287 * the mr_pt_fn callback, see mac_rx_common(). This is used in
288 * cases where there is another module acting as MAC provider on
289 * behalf of the driver. E.g., link aggregations use this mode to
290 * take full control of the port's rings; allowing it to enforce
291 * LACP protocols and aggregate rings across discrete drivers.
