Multiple group support is provided by mapping the set of enabled queues to different groups and then programming the per group regsiters imask, ievent, rstat, tstat.

The incoming packets can be classified into different queues based on filer rules (out of scope of this patch). The number of queues enabled will be based on a DTS entries fsl,num_tx_queues and fsl,num_rx_queues. Although we are enabling multiple queues, the interrupt coalescing is on per device level (etsec-1.7 doesn't support multiple rxics and txics).

The elements of this structure are the interrupt lines, their corresponding names, the register memory map. The elements for this group are factored out from the gfar_private structure. The introduction of group structure will help in providing support for newer versions of etsec. Currently, the support is present only for single group and single tx/rx queues.
