The first entries in the PGID table are used by the front ports while the last entries are used for different purposes like flooding mask, copy to CPU, etc. So add these macros to define which entries can be used for general purpose. Signed-off-by:

Extend mac functionality with the function lan966x_mac_ip_learn. This function adds an entry in the MAC table for IP multicast addresses. These entries can copy a frame to the CPU but also can forward on the front ports. This functionality is needed for mdb support. In case the CPU and some of the front ports subscribe to an IP multicast address. Signed-off-by:

Daniel Golle says: ==================== net: ethernet: mtk_eth_soc: refactoring and Clause 45 Rework value and type of mdio read and write functions in mtk_eth_soc and generally clean up and unify both functions. Then add support to access Clause 45 phy registers, using newly introduced helper inline functions added by a patch Russell King has suggested in a reply to an earlier version of this series [1]. All three commits are tested on the Bananapi BPi-R64 board having MediaTek MT7531BE DSA gigE switch using clause 22 MDIO and Ubiquiti UniFi 6 LR access point having Aquantia AQR112C PHY using clause 45 MDIO.

Instead of returning -1 (-EPERM) when MDIO bus is stuck busy while writing or 0xffff if it happens while reading, return the appropriate -ETIMEDOUT. Also fix return type to int instead of u32. Refactor functions to use bitfield helpers instead of having various masking and shifting constants in the code, which also results in the register definitions in the header file being more obviously related to what is stated in the MediaTek's Reference Manual.

Depending on BIOS configuration IOSM driver exchanges protocol required for putting device into D3L2 or D3L1.2. ipc_pcie_suspend_s2idle() is implemented to put device to D3L1.2. This patch forces PCI core know this device should stay at D0. - pci_save_state()is expensive since it does a lot of slow PCI config reads. The reported issue is not observed on x86 platform. The supurios wake on AMD platform needs to be futher debugged with orignal patch submitter [1]. Also the impact of adding pci_save_state() needs to be assessed by testing it on other platforms. This reverts commit f4dd5174("net: wwan: iosm: Keep device at D0 for s2idle case"). [1] https://lore.kernel.org/all/20211224081914.345292-2-kai.heng.feng@canonical.com/Signed-off-by:

When a mesh link is in blocked state, it is very useful to still allow auth requests from the peer to re-establish it. When a remote node is power cycled, the peer state can easily end up in blocked state if multiple auth attempts are performed. Since this can lead to several minutes of downtime, we should accept auth attempts of the peer after it has come back. Signed-off-by:

ieee80211_iterate_active_interfaces() and ieee80211_iterate_active_interfaces_atomic() already exist, where the former allows the iterator function to sleep. Add ieee80211_iterate_stations() which is similar to ieee80211_iterate_stations_atomic() but allows the iterator to sleep. This is needed for adding SDIO support to the rtw88 driver. Some interators there are reading or writing registers. With the SDIO ops (sdio_readb, sdio_writeb and friends) this means that the iterator function may sleep. Signed-off-by:

This patch adds support for scatter gather DMA. DMA in PMAC splits the packet into several buffers when the MTU on the CPU port is less than the MTU of the switch. The first buffer starts at an offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the offset. Thanks to this patch, the user can still connect to the device in such a situation. For normal configurations, the patch has no effect on performance. Signed-off-by:

Add support for external timestamp and periodic signal output. TJA1103 have one periodic signal and one external time stamp signal that can be multiplexed on all 11 gpio pins. The periodic signal can be only enabled or disabled. Have no start time and if is enabled will be generated with a period of one second in sync with the LTC seconds counter. The phase change is possible only with a half of a second. The external timestamp signal has no interrupt and no valid bit and that's why the timestamps are handled by polling in .do_aux_work.

Paul Blakey says: ==================== net/sched: Pass originating device to drivers offloading ct connection Currently, drivers register to a ct zone that can be shared by multiple devices. This can be inefficient for the driver to offload, as it needs to handle all the cases where the tuple can come from, instead of where it's most likely will arive from. For example, consider the following tc rules: tc filter add dev dev1 ... flower action ct commit zone 5 \ action mirred egress redirect dev dev2 tc filter add dev dev2 ... flower action ct zone 5 \ action goto chain chain 2 tc filter add dev dev2 ... flower ct_state +trk+est ... \ action mirred egress redirect dev dev1 Both dev2 and dev1 register to the zone 5 flow table (created by act_ct). A tuple originating on dev1, going to dev2, will be offloaded to both devices, and both will need to offload both directions, resulting in 4 total rules. The traffic will only hit originiating tuple on dev1, and reply tuple on dev2. By passing the originating device that created the connection with the tuple, dev1 can choose to offload only the originating tuple, and dev2 only the reply tuple. Resulting in a more efficient offload. The first patch adds an act_ct nf conntrack extension, to temporarily store the originiating device from the skb before offloading the connection once the connection is established. Once sent to offload, it fills the tuple originating device. The second patch get this information from tuples which pass in openvswitch. The third patch is Mellanox driver ct offload implementation using this information to provide a hint to firmware of where this offloaded tuple packets will arrive from (LOCAL or UPLINK port), and thus increase insertion rate. ==================== Signed-off-by: -

Get originating device from tuple offload metadata match ingress_ifindex, and set flow_source hint to either LOCAL for vf/sf reps, UPLINK for uplink/wire/tunnel devices/bond, or ANY (as before this patch) for all others. This allows lower layer (software steering or firmware) to insert the tuple rule only in one table (either rx or tx) instead of two (rx and tx). Signed-off-by:

Driver offloading ct tuples can use the information of which devices received the packets that created the offloaded connections, to more efficiently offload them only to the relevant device. Add new act_ct nf conntrack extension, which is used to store the skb devices before offloading the connection, and then fill in the tuple iifindex so drivers can get the device via metadata dissector match.

Use dma_set_mask_and_coherent() instead of unrolling it with some dma_set_mask()+dma_set_coherent_mask(). Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never fail if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. That said, 'high_dma' can only be 1 after a successful dma_set_mask_and_coherent(). Simplify code and remove some dead code accordingly, including a now useless parameter to vxge_device_register().
