IQK can change the values of this register set, so need to backup and restore the values. During we rewrite IQK, the policy is changed. Some values are controlled and filled by IQK, and don't need to restore after IQK. Therefore, remove this kind of registers from this array.

This significantly improves TCP segment coalescing and simplifies deployments as different workloads benefit from HW or SW GRO. - Shrink the size of the base zero-copy send structure. - Move TCP init under a new slow / sleepable version of DO_ONCE(). BPF: - Add BPF-specific, any-context-safe memory allocator. - Add helpers/kfuncs for PKCS#7 signature verification from BPF programs. - Define a new map type and related helpers for user space -> kernel communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF). - Allow targeting BPF iterators to loop through resources of one task/thread. - Add ability to call selected destructive functions. Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark.

Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible.

2022-10-04brcmfmac: Fix authentication latency caused by OBSS stats surveyRamesh Rangavittal
Auto Channel Select feature of HostAP uses dump_survey to fetch OBSS statistics. When the device is in the middle of an authentication sequence or just at the end of authentication completion, running dump_survey would trigger a channel change. The channel change in-turn can cause packet loss, resulting in authentication delay. With this change, dump_survey won't be run when authentication or association is in progress, hence resolving the issue.

When doing dump_survey, host will call "dump_obss" iovar to firmware side. Host need to make sure the HW clock in dongle is on, or there is high probability that firmware gets trap because register or shared memory access failed.

2022-10-04wifi: rtl8xxxu: gen2: Turn on the rate controlBitterblue Smith
Re-enable the function rtl8xxxu_gen2_report_connect. It informs the firmware when connecting to a network. This makes the firmware enable the rate control, which makes the upload faster. It also informs the firmware when disconnecting from a network. In the past this made reconnecting impossible because it was sending the auth on queue 0x7 (TXDESC_QUEUE_VO) instead of queue 0x12 (TXDESC_QUEUE_MGNT): wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 1/3) wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 2/3) wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 3/3) wlp0s20f0u3: authentication with 90:55:de:__:__:__ timed out Probably the firmware disables the unnecessary TX queues when it knows it's disconnected. However, this was fixed in commit edd5747aa12e ("wifi: rtl8xxxu: Fix skb misuse in TX queue selection").

Previously, we thought control registers or setting things for TX power series may change according to chip. So, setting functions are implemented chip by chip. However, until now, the functions keep the same among chips, at least 8852A, 8852C, and 8852B. There is a sufficient number of chips to share generic setting functions. So, we now remake them including TX power by rate, TX power offset, TX power limit, and TX power limit RU as generic ones in phy.c. Besides, there are some code refinements in the generic ones, but almost all of the logic doesn't change.

2022-10-03ethtool: add interface to interact with Ethernet Power EquipmentOleksij Rempel
Add interface to support Power Sourcing Equipment. At current step it provides generic way to address all variants of PSE devices as defined in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4 PoDL Power Sourcing Equipment (PSE). Currently supported and mandatory objects are: IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl This is minimal interface needed to control PSE on each separate ethernet port but it provides not all mandatory objects specified in IEEE 802.3-2018. Since "PoDL PSE" and "PSE" have similar names, but some different values I decide to not merge them and keep separate naming schema. This should allow as to be as close to IEEE 802.3 spec as possible and avoid name conflicts in the future. This implementation is connected to PHYs instead of MACs because PSE auto classification can potentially interfere with PHY auto negotiation. So, may be some extra PHY related initialization will be needed.

2022-10-03net/mlx5e: xsk: Optimize for unaligned mode with 3072-byte framesMaxim Mikityanskiy
When XSK frame size is 3072 (or another power of two multiplied by 3), KLM mechanism for NIC virtual memory page mapping can be optimized by replacing it with KSM. Before this change, two KLM entries were needed to map an XSK frame that is not a power of two: one entry maps the UMEM memory up to the frame length, the other maps the rest of the stride to the garbage page. When the frame length divided by 3 is a power of two, it can be mapped using 3 KSM entries, and the fourth will map the rest of the stride to the garbage page. All 4 KSM entries are of the same size, which allows for a much faster lookup. Frame size 3072 is useful in certain use cases, because it allows packing 4 frames into 3 pages. Generally speaking, other frame sizes equal to PAGE_SIZE minus a power of two can be optimized in a similar way, but it will require many more KSMs per frame, which slows down UMRs a little bit, but more importantly may hit the limit for the maximum number of KSM entries.

2022-10-03net/mlx5e: xsk: Print a warning in slow configurationsMaxim Mikityanskiy
On striding RQ, when the XSK frame size doesn't match the MKey page size, KLM is used for memory mappings, which is a slower mechanism than MTT or KSM. It may happen in two cases: 1. Frame size is not a power of two (only possible in the unaligned mode of XSK). 2. Frame size is 2048 bytes, and the firmware doesn't support MKey pages smaller than 4096 bytes. Depending on the case, print a warning and recommend to disable striding RQ or upgrade the firmware.

2022-10-03net/mlx5e: xsk: Use KLM to protect frame overrun in unaligned modeMaxim Mikityanskiy
XSK RQs support striding RQ linear mode, but the stride size may be bigger than the XSK frame size, because: 1. The stride size must be a power of two. 2. The stride size must be equal to the UMR page size. Each XSK frame is treated as a separate page, because they aren't necessarily adjacent in physical memory, so the driver can't put more than one stride per page. 3. The minimal MTT page size is 4096 on older firmware. That means that if XSK frame size is 2048 or not a power of two, the strides may be bigger than XSK frames. Normally, it's not a problem if the hardware enforces the MTU. However, traffic between vports skips the hardware MTU check, and oversized packets may be received. If an oversized packet is bigger than the XSK frame but not bigger than the stride, it will cause overwriting of the adjacent UMEM region. If the packet takes more than one stride, they can be recycled for reuse, so it's not a problem when the XSK frame size matches the stride size. Work around the above issue by leveraging KLM to make a more fine-grained mapping. The beginning of each stride is mapped to the frame memory, and the padding up to the closest power of two is mapped to the overflow page that doesn't belong to UMEM. This way, application data corruption won't happen upon receiving packets bigger than MTU.
