Add a pool of flow counters, based on flow counter bulks, removing the
need to allocate a new counter via a costly FW command during the flow
creation process. The time it takes to acquire/release a flow counter
is cut from ~50 [us] to ~50 [ns].
The pool is part of the mlx5 driver instance, and provides flow
counters for aging flows. mlx5_fc_create() was modified to provide
counters for aging flows from the pool by default, and
mlx5_destroy_fc() was modified to release counters back to the pool
for later reuse. If bulk allocation is not supported or fails, and for
non-aging flows, the fallback behavior is to allocate and free
individual counters.
The pool is comprised of three lists of flow counter bulks, one of
fully used bulks, one of partially used bulks, and one of unused
bulks. Counters are provided from the partially used bulks first, to
help limit bulk fragmentation.
The pool maintains a threshold, and strives to maintain the amount of
available counters below it. The pool is increased in size when a
counter acquisition request is made and there are no available
counters, and it is decreased in size when the last counter in a bulk
is released and there are more available counters than the threshold.
All pool size changes are done in the context of the
acquiring/releasing process.
The value of the threshold is directly correlated to the amount of
used counters the pool is providing, while constrained by a hard
maximum, and is recalculated every time a bulk is allocated/freed.
This ensures that the pool only consumes large amounts of memory for
available counters if the pool is being used heavily. When fully
populated and at the hard maximum, the buffer of available counters
consumes ~40 [MB].

Towards introducing the ability to allocate bulks of flow counters,
refactor the flow counter bulk query process, removing functions and
structs whose names indicated being used for flow counter bulk
allocation FW commands, despite them actually only being used to
support bulk querying, and migrate their functionality to correctly
named functions in their natural location, fs_counters.c.
Additionally, optimize the bulk query process by:
* Extracting the memory used for the query to mlx5_fc_stats so
that it is only allocated once, and not for each bulk query.
* Querying all the counters in one function call.

In user-space there's no way to distinguish why an mdb entry was deleted
and that is a problem for daemons which would like to keep the mdb in
sync with remote ends (e.g. mlag) but would also like to converge faster.
In almost all cases we'd like to age-out the remote entry for performance
and convergence reasons except when fast-leave is enabled. In that case we
want explicit immediate remote delete, thus add mdb flag which is set only
when the entry is being deleted due to fast-leave.

Johannes Berg says:
====================
We have a reasonably large number of changes:
* lots more HE (802.11ax) support, particularly things
relevant for the the AP side, but also mesh support
* debugfs cleanups from Greg
* some more work on extended key ID
* start using genl parallel_ops, as preparation for
weaning ourselves off RTNL and getting parallelism
* various other changes all over

Since virtio-vsock was introduced, the buffers filled by the host
and pushed to the guest using the vring, are directly queued in
a per-socket list. These buffers are preallocated by the guest
with a fixed size (4 KB).
The maximum amount of memory used by each socket should be
controlled by the credit mechanism.
The default credit available per-socket is 256 KB, but if we use
only 1 byte per packet, the guest can queue up to 262144 of 4 KB
buffers, using up to 1 GB of memory per-socket. In addition, the
guest will continue to fill the vring with new 4 KB free buffers
to avoid starvation of other sockets.
This patch mitigates this issue copying the payload of small
packets (< 128 bytes) into the buffer of last packet queued, in
order to avoid wasting memory.

HE allows peers to negotiate the aggregation fragmentation level to be used
during transmission. The level can be 1-3. The Ext element is added behind
the ADDBA request inside the action frame. The responder will then reply
with the same level or a lower one if the requested one is not supported.
This patch only handles the negotiation part as the ADDBA frames get passed
to the ATH11k firmware, which does the rest of the magic for us aswell as
generating the requests.

The Tegra EQOS driver already resets the MDIO bus at probe time via the
reset GPIO specified in the phy-reset-gpios device tree property. There
is no need to reset the bus again later on.
This avoids the need to query the device tree for the snps,reset GPIO,
which is not part of the Tegra EQOS device tree bindings. This quiesces
an error message from the generic bus reset code if it doesn't find the
snps,reset related delays.

Extended Key ID allows A-MPDU sessions while rekeying as long as each
A-MPDU aggregates only MPDUs with one keyid together.

1) Drop IEEE80211_HW_EXT_KEY_ID_NATIVE and let drivers directly set
the NL80211_EXT_FEATURE_EXT_KEY_ID flag.
2) Drop IEEE80211_HW_NO_AMPDU_KEYBORDER_SUPPORT and simply assume all
drivers are unable to handle A-MPDU key borders.
The new Extended Key ID API now requires all mac80211 drivers to set
NL80211_EXT_FEATURE_EXT_KEY_ID when they implement set_key() and can
handle Extended Key ID. For drivers not providing set_key() mac80211
itself enables Extended Key ID support, using the internal SW crypto
services.

Since ieee80211_tx_dequeue() must not be called with softirqs enabled
(i.e. from process context without proper disable of bottom halves),
we add a wrapper that disables bottom halves before calling
ieee80211_tx_dequeue()
The new function is named ieee80211_tx_dequeue_ni() just as all other
from-process-context versions found in mac80211.
The documentation of ieee80211_tx_dequeue() is also updated so it
mentions that the function should not be called from process context.

As specified in RFC7710, Captive Portal option contains a URL.

This option should also be treated as userland.
Hence, treat ND option 37 as userland (Captive Portal support)

Some applications set tiny SO_SNDBUF values and expect
TCP to just work. Recent patches to address CVE-2019-11478
broke them in case of losses, since retransmits might
be prevented.
We should allow these flows to make progress.
This patch allows the first and last skb in retransmit queue
to be split even if memory limits are hit.
It also adds the some room due to the fact that tcp_sendmsg()
and tcp_sendpage() might overshoot sk_wmem_queued by about one full
TSO skb (64KB size). Note this allowance was already present
in stable backports for kernels < 4.15
Note for < 4.15 backports :
tcp_rtx_queue_tail() will probably look like :
static inline struct sk_buff *tcp_rtx_queue_tail(const struct sock *sk)
{
struct sk_buff *skb = tcp_send_head(sk);
return skb ? tcp_write_queue_prev(sk, skb) : tcp_write_queue_tail(sk);
}

Since ERR_PTR() is an inline, not a macro, just open-code it
here so it's usable as an initializer, fixing the build in
brcmfmac.

Pull dma-mapping fixes from Christoph Hellwig:
"Fix various regressions:
- force unencrypted dma-coherent buffers if encryption bit can't fit
into the dma coherent mask (Tom Lendacky)
- avoid limiting request size if swiotlb is not used (me)
- fix swiotlb handling in dma_direct_sync_sg_for_cpu/device (Fugang
Duan)"
* tag 'dma-mapping-5.3-1' of git://git.infradead.org/users/hch/dma-mapping:
dma-direct: correct the physical addr in dma_direct_sync_sg_for_cpu/device
dma-direct: only limit the mapping size if swiotlb could be used
dma-mapping: add a dma_addressing_limited helper
dma-direct: Force unencrypted DMA under SME for certain DMA masks
