Subject: [PATCH] net: airoha: Add dma_rmb() and READ_ONCE() in
airoha_qdma_rx_process()
Add missing dma_rmb() in airoha_qdma_rx_process routine to make sure the
DMA read operations are completed when the NIC reports the processing on
the current descriptor is done. Moreover, add missing READ_ONCE() in
airoha_qdma_rx_process() for DMA descriptor control fields in order to
avoid any compiler reordering.

Subject: [PATCH] net: airoha: Add missing PPE configurations in
airoha_ppe_hw_init()
Add the following PPE configuration in airoha_ppe_hw_init routine:
- 6RD hw offloading is currently not supported by Netfilter flowtable.
Disable explicitly PPE 6RD offloading in order to prevent PPE to learn
6RD flows and eventually interrupt the traffic.
- Add missing PPE bind rate configuration for L3 and L2 traffic.
PPE bind rate configuration specifies the pps threshold to move a PPE
entry state from UNBIND to BIND. Without this configuration this value
is random.
- Set ageing thresholds to the values used in the vendor SDK in order to
improve connection stability under load and avoid packet loss caused by
fast aging.

Subject: [PATCH] net: airoha: Fix FE_PSE_BUF_SET configuration if PPE2 is
available
airoha_fe_set routine is used to set specified bits to 1 in the selected
register. In the FE_PSE_BUF_SET case this can due to a overestimation of
the required buffers for I/O queues since we can miss to set some bits
of PSE_ALLRSV_MASK subfield to 0. Fix the issue relying on airoha_fe_rmw
routine instead.

Subject: [PATCH] net: airoha: Fix memory leak in airoha_qdma_rx_process()
If an error occurs on the subsequents buffers belonging to the
non-linear part of the skb (e.g. due to an error in the payload length
reported by the NIC or if we consumed all the available fragments for
the skb), the page_pool fragment will not be linked to the skb so it will
not return to the pool in the airoha_qdma_rx_process() error path. Fix the
memory leak partially reverting commit 'd6d2b0e1538d ("net: airoha: Fix
page recycling in airoha_qdma_rx_process()")' and always running
page_pool_put_full_page routine in the airoha_qdma_rx_process() error

Subject: [PATCH] net: airoha: Fix VIP configuration for AN7583 SoC
EN7581 and AN7583 SoCs have different VIP definitions. Introduce
get_vip_port callback in airoha_eth_soc_data struct in order to take
into account EN7581 and AN7583 VIP register layout and definition
differences.
Introduce nbq parameter in airoha_gdm_port struct. At the moment nbq
is set statically to value previously used in airhoha_set_gdm2_loopback
routine and it will be read from device tree in subsequent patches.

Remove airoha_gdm_port dependency in airoha_dev_setup_tc_block routine

does not introduce any logical change and it is a preliminary patch to
support multiple net_devices connected to the GDM3 or GDM4 ports via an
external hw arbiter.

From 8baf4bf72ef94c955ef89d4644f1986603ee8320 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/4] net: airoha: Rely on net_device pointer in HTB callbacks
Remove airoha_gdm_port dependency in HTB tc callback signatures and rely
on net_device pointer instead. Please note this patch does not introduce
any logical change and it is a preliminary patch in order to support
multiple net_devices connected to the same GDM3 or GDM4 port via an
external hw arbiter.

Subject: [PATCH 4/4] net: airoha: Remove PCE_MC_EN_MASK bit in REG_FE_PCE_CFG
configuration
PCE_MC_EN_MASK bit in REG_FE_PCE_CFG configuration performed in
airoha_fe_init() is used to duplicate multicast packets and send a copy
to the CPU when the traffic is offloaded. This is necessary just if
it is requested by the user. Disable multicast packets duplication by
default.
