net: dsa: mt7530: use simple HSR offload helpers

2025-12-02T00:45:08+00:00

The "mtk" tagging protocol uses dsa_xmit_port_mask(), which means we can offload HSR packet duplication on transmit. Enable that feature.

net: dsa: mt7530: unexport mt7530_switch_ops

2025-12-02T00:45:06+00:00

Commit cb675afcddbb ("net: dsa: mt7530: introduce separate MDIO driver") exported mt7530_switch_ops for use from mt7530-mmio.c. Later in the patch set, mt7530-mmio.c used mt7530_probe_common() to access the mt7530_switch_ops still from mt7530.c - see commit 110c18bfed41 ("net: dsa: mt7530: introduce driver for MT7988 built-in switch"). This proves that exporting mt7530_switch_ops was unnecessary, so unexport it back.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

net: dsa: mt7530: use new GPIO line value setter callbacks

struct gpio_chip now has callbacks for setting line values that return an integer, allowing to indicate failures. Convert the driver to using them.

net: dsa: mt7530: Add AN7583 support

2025-05-28T00:07:52+00:00

Add Airoha AN7583 Switch support. This is based on Airoha EN7581 that is based on Mediatek MT7988 Switch. Airoha AN7583 require additional tweak to the GEPHY_CONN_CFG register to make the internal PHY work.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Cross-merge networking fixes after downstream PR (net-6.15-rc4). This pull includes wireless and a fix to vxlan which isn't in Linus's tree just yet. The latter creates with a silent conflict / build breakage, so merging it now to avoid causing problems. drivers/net/vxlan/vxlan_vnifilter.c 094adad91310 ("vxlan: Use a single lock to protect the FDB table") 087a9eb9e597 ("vxlan: vnifilter: Fix unlocked deletion of default FDB entry") https://lore.kernel.org/20250423145131.513029-1-idosch@nvidia.com No "normal" conflicts, or adjacent changes.

net: dsa: mt7530: sync driver-specific behavior of MT7531 variants

2025-04-24T01:46:03+00:00

MT7531 standalone and MMIO variants found in MT7988 and EN7581 share most basic properties. Despite that, assisted_learning_on_cpu_port and mtu_enforcement_ingress were only applied for MT7531 but not for MT7988 or EN7581, causing the expected issues on MMIO devices. Apply both settings equally also for MT7988 and EN7581 by moving both assignments form mt7531_setup() to mt7531_setup_common(). This fixes unwanted flooding of packets due to unknown unicast during DA lookup, as well as issues with heterogenous MTU settings.

net: dsa: mt7530: implement .get_stats64

2025-04-15T10:10:21+00:00

It was reported that the internally calculated counter might differ from the real one from the Switch MIB. This can happen if the switch directly forward packets between the ports or offload small packets like ARP request. In such case, the kernel counter will desync compared to the real one transmitted and received by the Switch. To correctly provide the real info to the kernel, implement .get_stats64 that will directly read the current MIB counter from the switch register.
