39abbaef19 caif-hsi: Postpone init of HSI until open()
Do the initialization of the HSI interface when the
interface is opened, instead of upon registration.
When the interface is closed the HSI interface is
de-initialized, allowing other modules to use the
HSI interface.

Pull networking fixes from David Miller:

 1) Fix bluetooth userland regression reported by Keith Packard, from
    Gustavo Padovan.

 2) Revert ath9k PS idle change, from Sujith Manoharan.

 3) Correct default TCP memory limits (again), from Eric Dumazet.

 4) Fix tcp_rcv_rtt_update() accidental use of unscaled RTT, from Neal
    Cardwell.

 5) We made a facility for layers like wireless to say how much tailroom
    they need in the SKB for link layer stuff such as wireless
    encryption etc., but TCP works hard to fill every SKB out to the end
    defeating this specification.

    This leads to every TCP packet getting reallocated by the wireless
    code in order to have the right amount of tailroom available.

    Fix TCP to only fill SKBs out to the real amount of data area it
    asked for during the allocation, this way it won't eat into the
    slack added for the device's tailroom needs.

    Reported by Marc Merlin and fixed by Eric Dumazet.

 6) Leaks, endian bugs, and new device IDs in bluetooth from Santosh
    Nayak, João Paulo Rechi Vita, Cho, Yu-Chen, Andrei Emeltchenko,
    AceLan Kao, and Andrei Emeltchenko.

 7) OOPS on tty_close fix in bluetooth's hci_ldisc from Johan Hovold.

 8) netfilter erroneously scales TCP window twice, fix from Changli Gao.

 9) Memleak fix in wext-core from Julia Lawall.

10) Consistently handle invalid TCP packets in ipv4 vs.  ipv6 conntrack,
    from Jozsef Kadlecsik.

11) Validate IP header length properly in netfilter conntrack's
    ipv4_get_l4proto().

This adds a DFS pattern detector to ath9k. It is fed with pulse events
by the radar pulse detector and reports in place whether a pattern
was detected. On detection, the result is reported as radar event to
the DFS management component in the upper layer.

Currently the ETSI DFS domain is supported with detector lines for
the patterns defined by EN-301-893 v1.5.1. Support for FCC and JP
will be added gradually.

To include the pattern detector, ath9k must be built with support
for DFS certified config flag set (CONFIG_ATH9K_DFS_CERTIFIED).

4b6f1dd6a6 mac80211: add explicit monitor interface if needed
The queue mapping redesign that I'm planning to do
will break pure injection unless we handle monitor
interfaces explicitly. One possible option would
be to have the driver tell mac80211 about monitor
mode queues etc., but that would duplicate the API
since we already need to have queue assignments
handled per virtual interface.

So in order to solve this, have a virtual monitor
interface that is added whenever all active vifs
are monitors. We could also use the state of one
of the monitor interfaces, but managing that would
be complicated, so allocate separate state.

a7959c1394 rtlwifi: Preallocate USB read buffers and eliminate kalloc in read routine
The current version of rtlwifi for USB operations uses kmalloc to
acquire a 32-bit buffer for each read of the device. When
_usb_read_sync() is called with the rcu_lock held, the result is
a "sleeping function called from invalid context" BUG. This is
reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775.
The first case has the lock originating from within rtlwifi and could
be fixed by rearranging the locking; however, the second originates from
within mac80211. The kmalloc() call is removed from _usb_read_sync()
by creating a ring buffer pointer in the private area and
allocating the buffer data in the probe routine.

Unfortunately though, the iwlwifi and iwlegacy

control API to start with), so add a new field
"status.antenna" for them, at least for now.

In the future, I plan to use the new field to
hold the hardware queue, while the SKB's queue
mapping holds the AC.

Remove the WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL and add
it only if either the driver has remain_on_channel
implemented in the driver/device.

Also add it to all drivers that advertise P2P right
now since those definitely have to have it working.

a75e2ad772 rtlwifi: Add missing DMA buffer unmapping for PCI drivers
In https://bugzilla.kernel.org/show_bug.cgi?id=42976, a system with driver
rtl8192se used as an AP suffers from "Out of SW-IOMMU space" errors. These
are caused by the DMA buffers used for beacons never being unmapped.
