[PATCH net-next v8 0/3] airoha: add the capability to configure GDM3/GDM4 as WAN/LAN on demand

[Lorenzo Bianconi]

> Add the capability to configure GDM3/GDM4 as WAN/LAN on demand when QoS
> offload is created or destroyed.
> Make dev->qdma an RCU pointer so the TX path can safely dereference it
> without holding RTNL.
> Introduce airoha_qdma_start() and airoha_qdma_stop() helpers.
> 
> ---
> Changes in v8:
> - Rebase on top of next-next to fix conflicts.
> - Link to v7: https://lore.kernel.org/r/20260701-airoha-ethtool-priv_flags-v7-0-b4153bd44428@kernel.org
> 
> Changes in v7:
> - Fix ETS stats accounting in patch 2/3
> - Reset ETS stats accounting in airoha_dev_set_qdma().
> - Link to v6: https://lore.kernel.org/r/20260629-airoha-ethtool-priv_flags-v6-0-86bc600d31bc@kernel.org
> 
> Changes in v6:
> - Rebase on top of next-next
> - Add patch 1/3: "rename airoha_priv_flags to airoha_dev_flags"
> - Drop patch 2/3: "refactor QDMA start/stop into reusable helpers"
> - Link to v5: https://lore.kernel.org/r/20260611-airoha-ethtool-priv_flags-v5-0-c11de08486d1@kernel.org
> 
> Changes in v5:
> - Add patch 1/3: use int instead of atomic_t for qdma users counter
> - Protect dev->flags with flow_offload_mutex mutex.
> - Introduce AIROHA_PRIV_F_QOS in order to handle better WAN/LAN
>   switching.
> - Link to v4: https://lore.kernel.org/r/20260610-airoha-ethtool-priv_flags-v4-0-60e89cf28fea@kernel.org
> 
> Changes in v4:
> - Move back QDMA TX/RX DMA enable to airoha_dev_open()/airoha_dev_stop().
> - Configure GDM3/4 as WAN if GDM2 is not available in ndo_init()
>   callback.
> - Protect qdma pointer in airoha_gdm_dev struct using RCU.
> - Rely on rtnl_dereference() to access qdma pointer in the control path.
> - Add airoha_qdma_start() and airoha_qdma_stop() utility routines in
>   patch 1/2
> - Link to v3: https://lore.kernel.org/r/20260608-airoha-ethtool-priv_flags-v3-1-3e8e3dc3f715@kernel.org
> 
> Changes in v3:
> - Do not introduce ethtool private flags support to configure LAN/WAN
>   for GDM3/4 and rely on tc qdisc offload for it instead.
> - Set GDM3/4 ports as LAN by default.
> - Move QDMA TX/RX DMA enable from airoha_dev_open() to airoha_probe()
>   and the corresponding disable from airoha_dev_stop() to airoha_qdma_cleanup().
> - Link to v2: https://lore.kernel.org/r/20260607-airoha-ethtool-priv_flags-v2-1-742c7aa1e182@kernel.org

> Changes in v2:
> - Rework airoha_dev_set_wan_flag routine
> - Enable GDM_STRIP_CRC_MASK in airoha_disable_gdm2_loopback()
> - Do not always reset REG_SRC_PORT_FC_MAP6 in
>   airoha_disable_gdm2_loopback() but use the same condition used in
>   airoha_enable_gdm2_loopback().

Hi all,

I noticied this series, even if it is properly acked/reviewed, it is marked as
'New, archived' in patchwork:

https://patchwork.kernel.org/project/netdevbpf/cover/20260703-airoha-ethtool-priv_flags-v8-0-015ba5ac89ee@kernel.org/

I'm not entirely sure what the next steps should be for this series.
Thanks in advance.

Regards,
Lorenzo
