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. Currently a runtime decision based on the chip type is used to distinguish the HW differences between the SoC families. This patch series is in preparation for supporting the RZ/G2L SoC by replacing driver data chip type with struct ravb_hw_info by moving chip type to it and also adding gstrings_stats, gstrings_size, net_hw_features, net_features, num_gstat_queue, num_tx_desc, stats_len, skb_sz variables to it. This patch also adds the feature bit for {RX, TX} clock internal delays and TX Drop counters HW features found on R-Car Gen3 to struct ravb_hw_info. This patch series is based on net-next. v1->v2: * Replaced driver data chip type with struct ravb_hw_info * Added gstrings_stats, gstrings_size, net_hw_features, net_features, num_gstat_queue, num_tx_desc, stats_len, skb_sz to struct ravb_hw_info * Added internal_delay and tx_drop_cntrs hw feature bit to struct ravb_hw_info RFC->V1 * Incorporated feedback from Andrew, Sergei, Geert and Prabhakar * https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=515525 Biju Das (8): ravb: Add struct ravb_hw_info to driver data ravb: Add skb_sz to struct ravb_hw_info ravb: Add num_gstat_queue to struct ravb_hw_info ravb: Add stats_len to struct ravb_hw_info ravb: Add gstrings_stats and gstrings_size to struct ravb_hw_info ravb: Add net_features and net_hw_features to struct ravb_hw_info ravb: Add internal delay hw feature to struct ravb_hw_info ravb: Add tx_drop_cntrs to struct ravb_hw_info drivers/net/ethernet/renesas/ravb.h | 18 +++++ drivers/net/ethernet/renesas/ravb_main.c | 91 ++++++++++++++++-------- 2 files changed, 80 insertions(+), 29 deletions(-)
