Johannes Berg b5bde374f0 mac80211: fix warnings in ieee80211_if_config
The last warning can never trigger, and the explicit AP_VLAN
check is pointless if we move the config_interface check down,
in practice config_interface is required anyway.

Sujith c2da50e583 ath9k: Fix bug in handling single stream stations
AP mode currently sets up the dual stream capability
for all stations. This patch fixes it by checking if the
associated station supports dual stream MCS rates (8-15).
We would disregard any MCS rates above 15, since Atheros
HW supports only 0..15 rates currently, and can't receive
at rates > 15 anyway.

Luis R. Rodriguez b572b24c57 ath9k: remove dummy PCI "retry timeout" fix
Remove the PCI retry timeout code as that was just taken from ipw2100
due to historical reasons but in reality its a no-op, additionally its
simply incorrect as each PCI devices has its own custom PCI configuration
space on PCI config space >= 0x40. Not to mention we were trying to write
0 to a place that already has 0 on it.

Helmut Schaa 11432379fd mac80211: start pending scan after probe/auth/assoc timed out
If a scan is queued in STA mode while the interface is in state direct
probe, authenticate or associate the scan is delayed until the interface
enters disabled or associated state. But in case of direct probe-,
authentication- or association- timeout sta_work will not be scheduled
anymore (without external trigger) and thus the pending scan is not
executed and prevents a new scan from being triggered (-EBUSY).

Fix this by queueing the sta work again after direct probe-, authentication-
and association- timeout.

Johannes Berg 51b381479f mac80211: reduce max number of queues
No hw/driver actually supports more than four queues right now,
and we allocate a number of things per queue which means we
waste a bit of memory. Reduce the maximum number to four to
accurately reflect what we do (and need for QoS). Even if we
had hardware supporting more queues we couldn't take advantage
of that right now anyway.

Reinette Chatre 633e24ed95 cfg80211/nl80211: remove usage of CONFIG_NL80211
The scan capability added to cfg80211/nl80211 introduced a
dependency on nl80211 by cfg80211. We can thus no longer have
just cfg80211 without nl80211. Specifically, cfg80211_scan_done()
calls nl80211_send_scan_aborted() or nl80211_send_scan_done().

Now we remove the option for user to select nl80211. It will always
be compiled if user selects cfg80211.

Anton Vorontsov 79675900cb ucc_geth: Fix three oopses in PHY {de,}initialization code
When there are no free snums, UCC ethernet should gracefully fail, but
currently it oopses this way:

  # ifconfig eth0 up
  fill_init_enet_entries: Can not get SNUM.
  ucc_geth_startup: Can not fill p_init_enet_param_shadow.
  eth0: Cannot configure net device, aborting.
  Unable to handle kernel paging request for data at address 0x00000190
  Faulting instruction address: 0xc0294c88
  Oops: Kernel access of bad area, sig: 11 [#1]
  [...]

  [efb25df0] [c020eec0] dev_open+0xc0/0x118
  [...]

This is because the ucc_geth_stop() routine assumes that ugeth->phydev
is always initialized by the ucc_geth_open(), while it is not in case
of errors.

If we add a check to the ucc_geth_stop(), then another oops pops up:

  Unable to handle kernel paging request for data at address 0x00000004
  Faulting instruction address: 0xc01b46a4
  Oops: Kernel access of bad area, sig: 11 [#1]

  [ef83bff0] [c000f464] kernel_thread+0x4c/0x68
  [...]

That one happens because ucc_geth_stop() does not call phy_disconnect()
and so phylib state machine is running without any idea that a MAC has
just died.

Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY
is disabled, we'll get this oops:

  0:01 not found
  eth2: Could not attach to PHY
  eth2: Cannot initialize PHY, aborting.
  Unable to handle kernel paging request for data at address 0x00000190

  [ef82bff0] [c000f464] kernel_thread+0x4c/0x68
  [...]

And again, ucc_geth_stop() assumes that ugeth->phydev is there, while
it isn't.

This patch fixes all three oopses simply by rearranging some code:

- In ucc_geth_open(): move init_phy() call to the beginning, so
  that we only call ucc_geth_stop() with a PHY attached;
- Move phy_disconnect() call from ucc_geth_close() to
  ucc_geth_stop(), so that we'll always disconnect the PHY.

Dmitri Vorobiev cc0be3227d net: Add missing include into include/linux/netdevice.h
The inline function skb_gro_mac_header defined in include/linux/netdevice.h
makes use of page_address(). Depending on configuration options, the latter
is either defined as a macro or is declared as a function in another header
file, namely include/linux/mm.h. However, include/linux/netdevice.h does not
include include/linux/mm.h.

On MIPS, this has produced the following build error:

  CC      kernel/sysctl_check.o
In file included from include/linux/icmpv6.h:173,
