-Subject: [PATCH] net/fq_impl: do not maintain a backlog-sorted list of
- flows
-
-A sorted flow list is only needed to drop packets in the biggest flow when
-hitting the overmemory condition.
-By scanning flows only when needed, we can avoid paying the cost of
-maintaining the list under normal conditions
-In order to avoid scanning lots of empty flows and touching too many cold
-cache lines, a bitmap of flows with backlog is maintained

-Subject: [PATCH] mac80211: add rx decapsulation offload support
-
-This allows drivers to pass 802.3 frames to mac80211, with some restrictions:
-
-- the skb must be passed with a valid sta
-- fast-rx needs to be active for the sta
-- monitor mode needs to be disabled
-
-mac80211 will tell the driver when it is safe to enable rx decap offload for
-a particular station.
-
-In order to implement support, a driver must:
-
-- call ieee80211_hw_set(hw, SUPPORTS_RX_DECAP_OFFLOAD)
-- implement ops->sta_set_decap_offload
-- mark 802.3 frames with RX_FLAG_8023
-
-If it doesn't want to enable offload for some vif types, it can mask out
-IEEE80211_OFFLOAD_DECAP_ENABLED in vif->offload_flags from within the
-.add_interface or .update_vif_offload driver ops

-Subject: [PATCH] mac80211: enable QoS support for nl80211 ctrl port
-
-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.
-My NIC: Intel(R) Centrino(R) Ultimate-N 6300 AGN, REV=0x74

-Subject: [PATCH] mac80211: minstrel_ht: add support for OFDM rates on
- non-HT clients
-
-The legacy minstrel code is essentially unmaintained and receives only very
-little testing. In order to bring the significant algorithm improvements from
-minstrel_ht to legacy clients, this patch adds support for OFDM rates to
-minstrel_ht and removes the fallback to the legacy codepath.
-This also makes it work much better on hardware with rate selection constraints,
-e.g. mt76.

-Subject: [PATCH] mac80211: minstrel_ht: fix rounding error in throughput
- calculation
-
-On lower data rates, the throughput calculation has a significant rounding
-error, causing rates like 48M and 54M OFDM to share the same throughput
-value with >= 90% success probablity.
-
-This is because the result of the division (prob_avg * 1000) / nsecs
-is really small (8 in this example).
-
-Improve accuracy by moving over some zeroes, making better use of the full
-range of u32 before the division.

-Subject: [PATCH] mac80211: minstrel_ht: reduce the need to sample slower
- rates
-
-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

-Subject: [PATCH] mac80211: minstrel_ht: significantly redesign the rate
- probing strategy
-
-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.
-

-Subject: [PATCH] mac80211: minstrel_ht: remove sample rate switching code for
- constrained devices
-
-This was added to mitigate the effects of too much sampling on devices that
-use a static global fallback table instead of configurable multi-rate retry.
-Now that the sampling algorithm is improved, this code path no longer performs
-any better than the standard probing on affected devices.

-
-We need to skip sampling if the next sample time is after jiffies, not before.
-This patch fixes an issue where in some cases only very little sampling (or none
-at all) is performed, leading to really bad data rates
