The structure is used as the argument to the \fBmr_gget\fR(9E) driver entry point when querying the group and its capabilities. .SH STRUCTURE MEMBERS .sp .in +2 .nf mac_group_driver_t mgi_driver; mac_group_start_t mgi_start; mac_group_stop_t mgi_stop; uint_t mgi_count; mac_group_flags_t mgi_flags; mac_group_addmac_t mgi_addmac; mac_group_remmac_t mgi_remmac; mac_group_addvlan_t mgi_addvlan; mac_group_remvlan_t mgi_remvlan; mac_group_setmtu_t mgi_setmtu; mac_group_getsriov_info_t mgi_getsriov_info; .fi .in -2 .sp .sp .ne 2 .mk .na \fB\fImgi_driver\fR\fR .ad .RS 21n .rt Filled by the driver as handle to the driver's group structure. .RE .sp .ne 2 .mk .na \fB\fImgi_start\fR\fR .ad .RS 21n .rt The driver entry point for starting a driver's ring group. .RE .sp .ne 2 .mk .na \fB\fImgi_stop\fR\fR .ad .RS 21n .rt The driver entry point for stopping a driver ring group. .RE .sp .ne 2 .mk .na \fB\fImgi_count\fR\fR .ad .RS 21n .rt The number of rings that are members of this ring group. .RE .sp .ne 2 .mk .na \fB\fImgi_flags\fR\fR .ad .RS 21n .rt Set by the driver to indicate various ring group capabilities including whether the group is the default ring group for the interface, whether the group is a pool of non-active rings, whether the group implements tagging/stripping for all VLANs, or implements transparent VLANs. .RE .sp .ne 2 .mk .na \fB\fImgi_addmac\fR\fR .ad .RS 21n .rt The driver entry point to program a MAC address into the driver's hardware for this ring group. This entry is only for RX ring groups. For SRIOV-capable devices, the \fBMAC_GROUP_MACADDR_PRIMARY\fR flag will be used to identify which of the MAC addressed for the group is the primary MAC address of the VF. .RE .sp .ne 2 .mk .na \fB\fImgi_remmac\fR\fR .ad .RS 21n .rt The driver entry point to remove a previously programmed MAC address. .RE .sp .ne 2 .mk .na \fB\fImgi_addvlan\fR\fR .ad .RS 21n .rt The driver entry point to add a VLAN filter to the ring group. The \fBMAC_VLAN_FILTER_TAG_ENABLE\fR flag will be set if the group is to provide tagging/stripping offload. .RE .sp .ne 2 .mk .na \fB\fImgi_remvlan\fR\fR .ad .RS 21n .rt The driver entry point to remove a VLAN filter. .RE .sp .ne 2 .mk .na \fB\fImgi_setmtu\fR\fR .ad .RS 21n .rt The driver entry point for the MAC layer to set the MTU for the ring group. .RE .sp .ne 2 .mk .na \fB\fImgi_getsriov_info\fR\fR .ad .RS 21n .rt The driver entry point to get the SRIOV information associated with this group. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
