mac80211: use rhashtable for station table
We currently have a hand-rolled table with 256 entries and are
using the last byte of the MAC address as the hash. This hash
is obviously very fast, but collisions are easily created and
we waste a lot of space in the common case of just connecting
as a client to an AP where we just have a single station. The
other common case of an AP is also suboptimal due to the size
of the hash table and the ease of causing collisions.
Convert all of this to use rhashtable with jhash, which gives
us the advantage of a far better hash function (with random
perturbation to avoid hash collision attacks) and of course
that the hash table grows and shrinks dynamically with chain
length, improving both cases above.
Use a specialised hash function (using jhash, but with fixed
length) to achieve better compiler optimisation as suggested
by Sergey Ryazanov.

With IPv6 addresses, every such place currently has to use generic nla_put
and nla_memcpy. Implementing IPv6 address access functions simplify things
and makes the code more intelligible. IPv4 address access functions has
lesser value but it would be better to be consistent between IPv6 and IPv4
and they still serve as documentation.
The conversion is straightforward and the resulting patches are not that
large, thus I kept all the changes in the patches that introduce the access
functions. If anyone prefers to split the definition of access functions and
the conversion and/or break it out by network protocols, please let me know.
While doing the conversion, I came across ugly typecasting in
inetpeer_addr_base and xfrm_address_t when dealing with IPv6 addresses.
Instead of introducing more of this, I cleaned it up. Those are the first
two patches, serving as a prerequisite to the latter two.

ptp: get ready for 2038
This series converts the core driver methods of the PTP Hardware Clock
(PHC) subsystem to use the 64 bit version of the timespec structure,
making the core API ready for the year 2038.
In addition, I reviewed how each driver and device represents the time
value at the hardware register level. Most of the drivers are ready,
but a few will need some work before the year 2038, as shown:
Patch Driver
------------------------------------------------
12 drivers/net/ethernet/intel/igb/igb_ptp.c
15 ? drivers/net/ethernet/sfc/ptp.c
16 drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c
The commit log messages document how each driver is ready or why it is
not ready. For patch 15, I could not easily find out the hardware
representation of the time value, and so the SFC maintainers will have
to review their low level code in order to resolve any remaining
issues.
* ChangeLog
** V3
- dp83640: use timespec64 throughout per Arnd's suggestion
- tilegx: use timespec64 throughout per Chris' suggestion
- add Jeff's acked-bys
** V2
- use the new methods in the posix clock code right away (patch #3)

mac80211: Fix misplaced return in AES-GMAC key setup
Commit
8ade538bf39b ("mac80111: Add BIP-GMAC-128 and BIP-GMAC-256
ciphers") had the success return in incorrect place before the
crypto_aead_setauthsize() call which practically ended up skipping that
call unconditionally.
The missing call did not actually change any functionality since
GMAC_MIC_LEN (16) is identical to the maxauthsize in gcm(aes) and as
such, the default value used for the authsize parameter.

cfg80211: pass name_assign_type to rdev_add_virtual_intf()
This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.
Similar functionality was introduced for the rtnetlink core in

mac80211: reject aggregation sessions with non-HT peers
If a peer or some local agent (rate control, ...) decides to start
an aggregation session but doesn't support HT (which also implies
QoS), reject it.
This is mostly a corner case as such peers normally won't try to
use block-ack sessions and rate control wouldn't start them, but
technically QoS stations could request it according to the spec.
However, since drivers don't really support such non-HT sessions
it's better to reject them.
Also, while at it, move the tracing for TX sessions earlier so it
captures the error cases as well.

Add a chandef to reg-class translation function to cfg80211 and use it
