Since internal_flags is only 8 bits, we can only have one more internal flag. However, we can obviously never use all of possible the combinations, in fact, we only use 14 of them (including no flags). Since we want more flags for MLO (multi-link operation) in the future, refactor the code to use a flags selector, so wrap all of the .internal_flags assignments in a IFLAGS() macro which selects the combination according to the pre- defined list of combinations. When we need a new combination, we'll have to add it, but again we will never use all possible combinations. Signed-off-by:

We haven't used this function for years, since commit c781944b ("cfg80211: Remove unused cfg80211_can_use_iftype_chan()") which itself removed a function unused since commit 97dc94f1 ("cfg80211: remove channel_switch combination check"), almost eight years ago. Also remove the now unused enum cfg80211_chan_mode and some struct members that were only used for this function.

This initial vesion is usable now. It can support STA, AP and monitor modes, so we can add 8852ce to Kconfig and Makefile. We are still working on some features, such as deep power save, and BT coexistence. But, this version still can have a good WiFi-only performance already, and will continue to fine tune power consumption. Signed-off-by:

Most drivers should not have to worry about selecting the right weight for their NAPI instances and pass NAPI_POLL_WEIGHT. It'd be best if we didn't require the argument at all and selected the default internally. This change prepares the ground for such reshuffling, allowing for a smooth transition. The following API should remain after the next release cycle: netif_napi_add() netif_napi_add_weight() netif_napi_add_tx() netif_napi_add_tx_weight() Where the _weight() variants take an explicit weight argument. I opted for a _weight() suffix rather than a __ prefix, because we use __ in places to mean that caller needs to also issue a synchronize_net() call. Signed-off-by:

Mat Martineau says: ==================== mptcp: Userspace path manager prerequisites This series builds upon the path manager mode selection changes merged in 4994d4fa ("Merge branch 'mptcp-path-manager-mode-selection'") to further modify the path manager code in preparation for adding the new netlink commands to announce/remove advertised addresses and create/destroy subflows of an MPTCP connection. The third and final patch series for the userspace path manager will implement those commands as discussed in https://lore.kernel.org/netdev/23ff3b49-2563-1874-fa35-3af55d3088e7@linux.intel.com/#r Patches 1, 5, and 7 remove some internal constraints on path managers (in general) without changing in-kernel PM behavior. Patch 2 adds a self test to validate MPTCP address advertisement ack behavior. Patches 3, 4, and 6 add new attributes to existing MPTCP netlink events and track internal state for populating those attributes. ==================== Link: https://lore.kernel.org/r/20220502205237.129297-1-mathew.j.martineau@linux.intel.comSigned-off-by:

This change updates internal logic to permit subflows to be established from either the client or server ends of MPTCP connections. This symmetry and added flexibility may be harnessed by PM implementations running on either end in creating new subflows. The essence of this change lies in not relying on the "server_side" flag (which continues to be available if needed). Acked-by:

Kishen Maloor authored
Per RFC 8684, if no port is specified in an ADD_ADDR message, MPTCP SHOULD attempt to connect to the specified address on the same port as the port that is already in use by the subflow on which the ADD_ADDR signal was sent. To facilitate that, this change reflects the specific remote port in use by that subflow in MPTCP_EVENT_ANNOUNCED events. Acked-by:

Kishen Maloor authored
This change reads the addr id assigned to the remote endpoint of a subflow from the MP_JOIN SYN/ACK message and stores it in the related subflow context. The remote id was not being captured prior to this change, and will now provide a consistent view of remote endpoints and their ids as seen through netlink events. Acked-by:

Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when there is an active userspace daemon. If the daemon is restarting or hasn't loaded yet, the missing echo will cause the peer to retransmit the ADD_ADDR - and hopefully the daemon will be ready to receive it at that later time.

Current limits on the # of addresses/subflows must apply only to in-kernel PM managed sockets. Thus this change removes such restrictions on connections overseen by non-kernel (e.g. userspace) PMs. This change also ensures that the kernel does not record stats inside struct mptcp_pm_data updated along kernel code paths when exercised via non-kernel PMs. Additionally, address announcements are acknolwedged and subflow requests are honored only when it's deemed that a userspace path manager is active at the time.

The following patch series tries to fix long standing issues with flow steering code and hopefully preventing silly future bugs. A) Fix an issue where a proper dest type wasn't assigned. B) Refactor and fix dests enums values, refactor deletion function and do proper bookkeeping of dests. C) Change mlx5_del_flow_rules() to delete rules when there are no no more rules attached associated with an FTE. D) Don't call hard coded deletion function but use the node's defined one.

Ido Schimmel says: ==================== mlxsw: Remove size limitations on egress descriptor buffer Petr says: Spectrum machines have two resources related to keeping packets in an internal buffer: bytes (allocated in cell-sized units) for packet payload, and descriptors, for keeping headers. Currently, mlxsw only configures the bytes part of the resource management. Spectrum switches permit a full parallel configuration for the descriptor resources, including port-pool and port-TC-pool quotas. By default, these are all configured to use pool 14, with an infinite quota. The ingress pool 14 is then infinite in size. However, egress pool 14 has finite size by default. The size is chip dependent, but always much lower than what the chip actually permits. As a result, we can easily construct workloads that exhaust the configured descriptor limit. Going forward, mlxsw will have to fix this issue properly by maintaining descriptor buffer sizes, TC bindings, and quotas that match the architecture recommendation. Short term, fix the issue by configuring the egress descriptor pool to be infinite in size as well. This will maintain the same configuration philosophy, but will unlock all chip resources to be usable. In this patchset, patch #1 first adds the "desc" field into the pool configuration register. Then in patch #2, the new field is used to configure both ingress and egress pool 14 as infinite. In patches #3 and #4, add a selftest that verifies that a large burst can be absorbed by the shared buffer. This test specifically exercises a scenario where descriptor buffer is the limiting factor and the test fails without the above patches. ==================== Link: https://lore.kernel.org/r/20220502084926.365268-1-idosch@nvidia.comSigned-off-by:

DPK is short for digital pre-distortion calibration. It can adjusts digital waveform according to PA linear characteristics dynamically to enhance TX EVM. Do this calibration when we are going to run on AP channel. To prevent power offset out of boundary, it monitors thermal and set proper boundary to register. 8852c needs two backup buffers, so we enlarge the array. But, 8852a still needs only one, so it only uses first element (index zero). Signed-off-by:
