The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are
similar to the R-Car Ethernet AVB IP.

The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal
TCP/IP Offload Engine (TOE)  and Dedicated Direct memory access controller
(DMAC).

With a few changes in the driver we can support both IPs.

This patch series is aims to add functional support for Gigabit Ethernet driver
by filling all the stubs except set_features.

set_feature patch will send as separate RFC patch along with rx_checksum
patch, as it needs detailed discussion related to HW checksum.

Ref:-
 https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=557655

RFC->V1:
 * Removed patch#3 will send it as RFC
 * Removed rx_csum functionality from patch#7, will send it as RFC
 * Renamed "nc_queue" -> "nc_queues"
 * Separated the comment patch into 2 separate patches.
 * Documented PFRI register bit
 * Added Sergy's Rb tag

RFC changes:
 * used ALIGN macro for calculating the value for max_rx_len.
 * used rx_max_buf_size instead of rx_2k_buffers feature bit.
 * moved struct ravb_rx_desc *gbeth_rx_ring near to ravb_private::rx_ring
   and allocating it for 1 RX queue.
 * Started using gbeth_rx_ring instead of gbeth_rx_ring[q].
 * renamed ravb_alloc_rx_desc to ravb_alloc_rx_desc_rcar
 * renamed ravb_rx_ring_free to ravb_rx_ring_free_rcar
 * renamed ravb_rx_ring_format to ravb_rx_ring_format_rcar
 * renamed ravb_rcar_rx to ravb_rx_rcar
 * renamed "tsrq" variable
 * Updated the comments

Biju Das (14):
  ravb: Use ALIGN macro for max_rx_len
  ravb: Add rx_max_buf_size to struct ravb_hw_info
  ravb: Fillup ravb_alloc_rx_desc_gbeth() stub
  ravb: Fillup ravb_rx_ring_free_gbeth() stub
  ravb: Fillup ravb_rx_ring_format_gbeth() stub
  ravb: Fillup ravb_rx_gbeth() stub
  ravb: Add carrier_counters to struct ravb_hw_info
  ravb: Add support to retrieve stats for GbEthernet
  ravb: Rename "tsrq" variable
  ravb: Optimize ravb_emac_init_gbeth function
  ravb: Rename "nc_queue" feature bit
  ravb: Document PFRI register bit
  ravb: Update EMAC configuration mode comment
  ravb: Fix typo AVB->DMAC

   DaveM, I'm going to review this patch series (starting on Monday). Is that acceptable forewarning? :-)

My Bad. Sorry will taken care this in future. I need to send V2, as accidentally I have added 2 macros in patch #6
As part of RFC discussion into v1. I will send V2 to remove this.

they should have landed on the OMP account too. :-/
