327 *
328 * MCIS_EXCLUSIVE
329 *
330 * The client has exclusive control over the MAC, such that it is
331 * the sole client of the MAC.
332 *
333 * MCIS_TAG_DISABLE
334 *
335 * MAC will not add VLAN tags to outgoing traffic. If this flag
336 * is set it is up to the client to add the correct VLAN tag.
337 *
338 * MCIS_STRIP_DISABLE
339 *
340 * MAC will not strip the VLAN tags on incoming traffic before
341 * passing it to mci_rx_fn. This only applies to non-bypass
342 * traffic.
343 *
344 * MCIS_IS_AGGR_PORT
345 *
346 * The client represents a port on an aggr.
347 *
348 * MCIS_CLIENT_POLL_CAPABLE
349 *
350 * The client is capable of polling the Rx TCP/UDP softrings.
351 *
352 * MCIS_DESC_LOGGED
353 *
354 * This flag is set when the client's link info has been logged
355 * by the mac_log_linkinfo() timer. This ensures that the
356 * client's link info is only logged once.
357 *
358 * MCIS_SHARE_BOUND
359 *
360 * This client has an HIO share bound to it.
361 *
362 * MCIS_DISABLE_TX_VID_CHECK
363 *
364 * MAC will not check the VID of the client's Tx traffic.
365 *
366 * MCIS_USE_DATALINK_NAME
367 *
368 * The client is using the same name as its underlying MAC. This
369 * happens when dlmgmtd is unreachable during client creation.
370 *
371 * MCIS_UNICAST_HW
372 *
373 * The client requires MAC address hardware classification. This
374 * is only used by sun4v vsw.
375 *
376 * MCIS_IS_AGGR_CLIENT
377 *
378 * The client sits atop an aggr.
379 *
380 * MCIS_RX_BYPASS_DISABLE
381 *
382 * Do not allow the client to enable DLS bypass.
383 *
384 * MCIS_NO_UNICAST_ADDR
385 *
386 * This client has no MAC unicast addresss associated with it.
