struct dsa_port has 5 bool members which create quite a number of 7 byte holes in the structure layout. By merging them all into bitfields of an u8, and placing that u8 in the 1-byte hole after dp->mac and dp->stp_state, we can reduce the structure size from 576 bytes to 552 bytes on arm64.

The MAC address of a port is 6 octets in size, and this creates a 2 octet hole after it. There are some other u8 members of struct dsa_port that we can put in that hole. One such member is the stp_state.

Currently PF and VF use two sets of command code for modules to interact with firmware. These codes values are same espect the macro names. It is redundent to keep two sets of command code for same functions between PF and VF. So this patch firstly creates a unified command code for PF and VF module. We keep the macro name same with the PF command code name to avoid too many meaningless modifications. Secondly the new common command codes are used to replace the old ones in VF and deletes the old ones. Signed-off-by:

Currently, there are two different sets of special command codes in PF and VF cmdq modules, this is because VF driver only uses small part of all the command codes. In other words, these not used command codes in VF are also sepcial command codes theoretically. So this patch unifes the special command codes and deletes the bool param is_pf of hclge_comm_send.

Extend lan966x driver with mdb support by implementing the switchdev calls: SWITCHDEV_OBJ_ID_PORT_MDB and SWITCHDEV_OBJ_ID_HOST_MDB. It is allowed to add both ipv4/ipv6 entries and l2 entries. To add ipv4/ipv6 entries is not required to use the PGID table while for l2 entries it is required. The PGID table is much smaller than MAC table so only fewer l2 entries can be added. 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:

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:
