2021-02-12i40e: adjust i40e_is_non_eopMaciej Fijalkowski
i40e_is_non_eop had a leftover comment and unused skb argument which was used for placing the skb onto rx_buf in case when current buffer was non-eop one. This is not relevant anymore as commit e72e56597ba1 ("i40e/i40evf: Moves skb from i40e_rx_buffer to i40e_ring") pulled the non-complete skb handling out of rx_bufs up to rx_ring. Therefore, let's adjust the function arguments that i40e_is_non_eop takes. Furthermore, since there is already a function responsible for bumping the ntc, make use of that and drop that logic from i40e_is_non_eop so that the scope of this function is limited to what the name actually states.

2021-02-12mac80211: minstrel_ht: significantly redesign the rate probing strategyFelix Fietkau
The biggest flaw in current minstrel_ht is the fact that it needs way too many probing packets to be able to quickly find the best rate. Depending on the wifi hardware and operating mode, this can significantly reduce throughput when not operating at the highest available data rate. In order to be able to significantly reduce the amount of rate sampling, we need a much smarter selection of probing rates. The new approach introduced by this patch maintains a limited set of available rates to be tested during a statistics window. They are split into distinct categories: - MINSTREL_SAMPLE_TYPE_INC - incremental rate upgrade: Pick the next rate group and find the first rate that is faster than the current max. throughput rate - MINSTREL_SAMPLE_TYPE_JUMP - random testing of higher rates: Pick a random rate from the next group that is faster than the current max throughput rate. This allows faster adaptation when the link changes significantly - MINSTREL_SAMPLE_TYPE_SLOW - test a rate between max_prob, max_tp2 and max_tp in order to reduce the gap between them In order to prioritize sampling, every 6 attempts are split into 3x INC, 2x JUMP, 1x SLOW. Available rates are checked and refilled on every stats window update. With this approach, we finally get a very small delta in throughput when comparing setting the optimal data rate as a fixed rate vs normal rate control operation.

2021-02-12mac80211: minstrel_ht: reduce the need to sample slower ratesFelix Fietkau
In order to more gracefully be able to fall back to lower rates without too much throughput fluctuations, initialize all untested rates below tested ones to the maximum probabilty of higher rates. Usually this leads to untested lower rates getting initialized with a probability value of 100%, making them better candidates for fallback without having to rely on random probing Signed-off-by: Felix Fietkau <nbd@nbd.name> Link: https://lore.kernel.org/r/20210127055735.78599-3-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2021-02-12cfg80211: initialize reg_rule in __freq_reg_info()Luca Coelho
Sparse started warning on this function because we can potentially return an uninitialized value. The reason is that if the caller passes a min_bw value that is higher then the last value in bws[], we will not go into the loop and reg_rule will remain initialized. This cannot happen because the only caller of this function uses either 1 or 20 in min_bw, but the function will be more robust if we pre-initialize the value.

2021-02-12mac80211: enable QoS support for nl80211 ctrl portMarkus Theil
This patch unifies sending control port frames over nl80211 and AF_PACKET sockets a little more. Before this patch, EAPOL frames got QoS prioritization only when using AF_PACKET sockets. __ieee80211_select_queue only selects a QoS-enabled queue for control port frames, when the control port protocol is set correctly on the skb. For the AF_PACKET path this works, but the nl80211 path used ETH_P_802_3. Another check for injected frames in wme.c then prevented the QoS TID to be copied in the frame. In order to fix this, get rid of the frame injection marking for nl80211 ctrl port and set the correct ethernet protocol. Please note: An erlier version of this path tried to prevent frame aggregation for control port frames in order to speed up the initial connection setup a little. This seemed to cause issues on my older Intel dvm-based hardware, and was therefore removed again. Future commits which try to reintroduce this have to check carefully how hw behaves with aggregated and non-aggregated traffic for the same TID.

2021-02-12rtw88: add napi supportPo-Hao Huang
Use napi to reduce overhead on rx interrupts. Driver used to interrupt kernel for every Rx packet, this could affect both system and network performance. NAPI is a mechanism that uses polling when processing huge amount of traffic, by doing this the number of interrupts can be decreased. Network performance can also benefit from this patch. Since TCP connection is bidirectional and acks are required for every several packets. These ack packets occupie the PCI bus bandwidth and could lead to performance degradation. When napi is used, GRO receive is enabled by default in the mac80211 stack. So mac80211 won't pass every RX TCP packets to the kernel TCP network stack immediately. Instead an aggregated large length TCP packet will be delivered. This reduces the tx acks sent and gains rx performance. After the patch, the Rx throughput increases about 25Mbps in 11ac.

2021-02-12rtw88: add dynamic rrsr configurationPo-Hao Huang
Register rrsr determines the response rate we send. In field tests, using rate higher than current tx rate could lead to difficulty for the receiving end to receive management/control frames. Calculate current modulation level by tx rate then cross out rate higher than those.

2021-02-12iwlwifi: remove incorrect comment in pnvmLuca Coelho
We use this driver as a backport that also runs on older kernels (as part of the backports project). So we use some checks to backport or prevent code from compiling in incompatible kernel version. When I took one of the PNVM patches from the backport, I accidentally left the comment that a certain part of the code doesn't work in older kernels. This obviously should never be valid for the mainline. Remove this comment.

2021-02-11Merge branch 'sock-rx-qmap'David S. Miller
Tariq Toukan says: ==================== Compile-flag for sock RX queue mapping Socket's RX queue mapping logic is useful also for non-XPS use cases. This series breaks the dependency between the two, introducing a new kernel config flag SOCK_RX_QUEUE_MAPPING. Here we select this new kernel flag from TLS_DEVICE, as well as XPS. ==================== Acked-by: Jakub Kicinski <kuba@kernel.org>
2021-02-11net/mlx5: Remove TLS dependencies on XPSTariq Toukan
No real dependency on XPS, but on RX queue mapping, which is being selected by TLS_DEVICE. Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Reviewed-by: Maxim Mikityanskiy <maximmi@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-02-11net/tls: Select SOCK_RX_QUEUE_MAPPING from TLS_DEVICETariq Toukan
Compile-in the socket RX queue mapping field and logic when TLS_DEVICE is enabled. This allows device drivers to pick the recorded socket's RX queue and use it for streams distribution.

2021-02-11net/sock: Add kernel config SOCK_RX_QUEUE_MAPPINGTariq Toukan
Use a new config SOCK_RX_QUEUE_MAPPING to compile-in the socket RX queue field and logic, instead of the XPS config. This breaks dependency in XPS, and allows selecting it from non-XPS use cases, as we do in the next patch. In addition, use the new flag to wrap the logic in sk_rx_queue_get() and protect access to the sk_rx_queue_mapping field, while keeping the function exposed unconditionally, just like sk_rx_queue_set() and sk_rx_queue_clear().
