Barak Bercovitz 2473ec8f90 wlcore: wakeup from ELP before starting recovery
Make sure the FW is awake when entering recovery. This is useful for
reading the FW panic log and also some FW registers giving us crash
report stats.

We must do this before interrupts are disabled since we rely on an
interrupt to complete the wakeup.

If the wakeup fails, continue recovery normally. All read/writes will be
blocked and won't do any harm.

Barak Bercovitz c2e6424259 wlcore: Allow stopping fw log in recovery
The FW panic log is read during recovery work.
It has to be stopped properly before reading. otherwise,
inconsistent data might be read which cause the driver
to freeze.

__wlcore_cmd_send has to work for the special case of
CMD_STOP_FWLOGGER, while in recovery, in order to stop
the fw log before it is read.

Igal Chernobelsky c83cb8031b wlcore/wl18xx/wl12xx: FW log params per chip arch
FW memory block size and FW log end marker parameters
are added to wl structure and are initialized per
chip architecture.

convert_hwaddr hw operation is added to convert chip
dependent FW internal address.

Copy from FW log is also simplified to copy the entire
memory block as FW logger utility is repsponsible
for parsing of FW log content.

Ido Reis 93ac8488a2 wlcore: fwlog dynamic mem_block control
number of fwlog mem_blocks can be configured using module param.
this is a fw debug feature: in case a large fw log data is busrted during
a short period of time, the memory get filled and data is lost.
this allows us to dynamicly set the fw log mem_block usage, although
configuring more mem_block for logger comes at the expense of TP.

Johannes Berg 1fb9026000 mac80211: move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into drivers
mac80211 currently sets WIPHY_FLAG_SUPPORTS_SCHED_SCAN based on whether
the start_sched_scan operation is supported or not, but that will not
be correct for all drivers, we're adding scheduled scan to the iwlmvm
driver but it depends on firmware support.

Therefore, move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into the drivers
so that they can control it regardless of implementing the operation.

This currently only affects the TI drivers since they're the only ones
implementing scheduled scan (in a mac80211 driver.)

Linus Torvalds 496322bc91 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller:
 "This is a re-do of the net-next pull request for the current merge
  window.  The only difference from the one I made the other day is that
  this has Eliezer's interface renames and the timeout handling changes
  made based upon your feedback, as well as a few bug fixes that have
  trickeled in.

  Highlights:

   1) Low latency device polling, eliminating the cost of interrupt
      handling and context switches.  Allows direct polling of a network
      device from socket operations, such as recvmsg() and poll().

      Currently ixgbe, mlx4, and bnx2x support this feature.

      Full high level description, performance numbers, and design in
      commit 0a4db187a9 ("Merge branch 'll_poll'")

      From Eliezer Tamir.

   2) With the routing cache removed, ip_check_mc_rcu() gets exercised
      more than ever before in the case where we have lots of multicast
      addresses.  Use a hash table instead of a simple linked list, from
      Eric Dumazet.

   3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
      Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
      Marek Puzyniak, Michal Kazior, and Sujith Manoharan.

   4) Support reporting the TUN device persist flag to userspace, from
      Pavel Emelyanov.

   5) Allow controlling network device VF link state using netlink, from
      Rony Efraim.

   6) Support GRE tunneling in openvswitch, from Pravin B Shelar.

   7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
      Daniel Borkmann and Eric Dumazet.

   8) Allow controlling of TCP quickack behavior on a per-route basis,
      from Cong Wang.

   9) Several bug fixes and improvements to vxlan from Stephen
      Hemminger, Pravin B Shelar, and Mike Rapoport.  In particular,
      support receiving on multiple UDP ports.

  10) Major cleanups, particular in the area of debugging and cookie
      lifetime handline, to the SCTP protocol code.  From Daniel
      Borkmann.

  11) Allow packets to cross network namespaces when traversing tunnel
      devices.  From Nicolas Dichtel.

  12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
      manner akin to how we monitor real network traffic via ptype_all.
      From Daniel Borkmann.

  13) Several bug fixes and improvements for the new alx device driver,
      from Johannes Berg.

  14) Fix scalability issues in the netem packet scheduler's time queue,
      by using an rbtree.  From Eric Dumazet.

  15) Several bug fixes in TCP loss recovery handling, from Yuchung
      Cheng.

  16) Add support for GSO segmentation of MPLS packets, from Simon
      Horman.

  17) Make network notifiers have a real data type for the opaque
      pointer that's passed into them.  Use this to properly handle
      network device flag changes in arp_netdev_event().  From Jiri
      Pirko and Timo Teräs.

  18) Convert several drivers over to module_pci_driver(), from Peter
      Huewe.

  19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
      O(1) calculation instead.  From Eric Dumazet.

  20) Support setting of explicit tunnel peer addresses in ipv6, just
      like ipv4.  From Nicolas Dichtel.

  21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.

  22) Prevent a single high rate flow from overruning an individual cpu
      during RX packet processing via selective flow shedding.  From
      Willem de Bruijn.

  23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
      Dumazet.

  24) Don't just drop GSO packets which are above the TBF scheduler's
      burst limit, chop them up so they are in-bounds instead.  Also
      from Eric Dumazet.

  25) VLAN offloads are missed when configured on top of a bridge, fix
      from Vlad Yasevich.

  26) Support IPV6 in ping sockets.  From Lorenzo Colitti.

  27) Receive flow steering targets should be updated at poll() time
      too, from David Majnemer.

  28) Fix several corner case regressions in PMTU/redirect handling due
      to the routing cache removal, from Timo Teräs.

  29) We have to be mindful of ipv4 mapped ipv6 sockets in
      upd_v6_push_pending_frames().  From Hannes Frederic Sowa.

  30) Fix L2TP sequence number handling bugs, from James Chapman."

Victor Goldenshtein 5cbba2d48a wlcore: fix occasional AP TX stop after recovery
The fw_status wasn't zeroed during allocation, resulting
in uninitialized var usage, and finally causing AP
traffic stop after recovery.

The wrong value in fw_status_2->counters.tx_lnk_free_pkts
led to a bad lnk->allocated_pkts calculation in
wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return
FALSE (lnk->allocated_pkts > thold).
This eventually blocked the link in wlcore_tx_work_locked(),
as wl1271_skb_dequeue() continuously returned NULL.

Eliad Peller 6f0b1bb2ba wlcore: configure rates in multiple cases
The current code configures the peer caps only on BSS_CHANGED_HT
notification. However, we have to configure the peer caps
(and rates) even when HT is not enabled. Otherwise, the fw
continues working with low rates.

Configure the peer caps when sta_exists is true (i.e. when
we extracted the sta rates, e.g. on association).

Luciano Coelho 33cab57a50 wlcore: move sysfs handling to a separate file
Instead of doing all the sysfs file handling in the main file, move it
to a new sysfs source file to reduce the amount of code in a single
file.

Ido Reis e3b8bbb9e8 wl18xx: FDSP Code RAM Corruption fix
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.

PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).

This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.

The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.

The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:

1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

Eliad Peller a805de4d03 wl12xx/wl18xx: scan all 5ghz channels
Due to a typo, the current code copies only sizeof(cmd->channels_2)
bytes, which is smaller than the correct sizeof(cmd->channels_5)
size, resulting in a partial scan (some channels are skipped).

Luciano Coelho 60c28cf18f wl12xx: fix minimum required firmware version for wl127x multirole
There was a typo in commit 8675f9 (wlcore/wl12xx/wl18xx: verify
multi-role and single-role fw versions), which was causing the
multirole firmware for wl127x (WiLink6) to be rejected.  The actual
minimum version needed for wl127x multirole is 6.5.7.0.42.

There's no need to take up the space for devices that don't
support WoWLAN, and most drivers can even make the support
data static const (except where it's modified at runtime.)
