!  * The type of ring classification. This is used by MAC to determine
!  * what, if any, processing it has to do upon receiving traffic on a
!  * particular Rx ring.
!  *
!  * MAC_NO_CLASSIFIER
!  *
!  *      No classification has been set. No traffic should cross an Rx
!  *      ring in this state.
!  *
!  * MAC_SW_CLASSIFIER
!  *
!  *      The driver delivers traffic for multiple clients to this ring.
!  *      All traffic must be software classified by MAC to guarantee
!  *      delivery to the correct client. This classification type may
!  *      be chosen for several reasons.
!  *
!  *      o The driver provides only one group and there are multiple
!  *        clients using the MAC.
!  *
!  *      o The driver provides some hardware filtering but not enough
!  *        to fully classify the traffic. E.g., a VLAN VNIC requires L2
!  *        unicast address filtering as well as VLAN filtering, but
!  *        some drivers may only support the former.
!  *
!  *      o The ring belongs to the default group. The default group
!  *        acts as a spillover for all clients that can't reserve an
!  *        exclusive group. It also handles multicast traffic for all
!  *        clients. For these reasons, the default group's rings are
!  *        always software classified.
!  *
!  * MAC_HW_CLASSIFIER
!  *
!  *      The driver delivers traffic for a single MAC client across
!  *      this ring. With this guarantee, MAC can simply pass the
!  *      traffic up the stack or even allow polling of the ring.
!  *
!  * MAC_PASSTHRU_CLASSIFIER
!  *
!  *      The ring is in "passthru" mode. In this mode we bypass all of
!  *      the typical MAC processing and pass the traffic directly to
!  *      the mr_pt_fn callback, see mac_rx_common(). This is used in
!  *      cases where there is another module acting as MAC provider on
!  *      behalf of the driver. E.g., link aggregations use this mode to
!  *      take full control of the port's rings; allowing it to enforce
!  *      LACP protocols and aggregate rings across discrete drivers.
