7367d0b573 drivers/net: Convert uses of compare_ether_addr to ether_addr_equal
Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.

Done via cocci script: (and a little typing)

6e956da202 rt2800: fix wrong TX power compensation
We should not do temperature compensation on devices without
EXTERNAL_TX_ALC bit set (called DynamicTxAgcControl on vendor driver).
Such devices can have totally bogus TSSI parameters on the EEPROM,
but still threaded by us as valid and result doing wrong TX power
calculations.

This fix inability to connect to AP on slightly longer distance on
some Ralink chips/devices.

634b80595f rt2x00: rt2800lib: don't hardcode beacon offsets
The values written into the BCN_OFFSET[01] registers are
hardcoded in the rt2800_init_register function.

Add a macro and a helper function to derive these values
directly from the base address of a given beacon, and use
the new function instead of the hardcoded numbers.

The patch contains no functional changes. The programmed
register values are the same before and after the patch.

21c6af6b69 rt2x00: rt2800lib: add rt2800_hw_beacon_base helper
The HW_BEACON_BASE() macro returns the base address
of a given beacon, however the returned values are
not usable on all chipsets. On devices which have
selectable shared memory parts, some beacon may be
located in the high part of the shared memory.

Instead of extending the already complicated macro,
add a new helper function and use that to get the
base address of a given beacon.

The actual patch contains no functional changes, the
helper function will be extended in a further patch
to handle different chipsets' requirements.

c1fada4e5e rt2x00: rt2800lib: fix frequency offset boundary calculation
The current code in the 'rt2800_adjust_freq_offset'
function limits the device specific frequency offset
value to FREQ_BOUND but ignores the fact that the
uppermost bit is not part of the frequency offset

FREQ_BOUND value if the uppermost bit is set.

for calculating the boundary.

ae1b1c5dcd rt2x00: rt2800lib: introduce rt2800_get_txwi_rxwi_size helper
The rt2800pci driver uses the same [RT]XWI size
for all chipsets, however some chips requires
different values.

The size of the [RT]XWI structures is a constant
value for a given chipset and it does not depend
on the underlying interface. Add a helper function
which returns the correct values for the actual
chipset and use the new helper both in the rt2800usb
and in the rt2800pci drivers. This ensures that both
drivers are using the correct values.

e2288b66fe rt2x00: fix stop queue
Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.

To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.

Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.

Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()
directly is the only available solution to fix the problem without
major rework.

fa31d157f8 rt2x00: rt2800lib: add EEPROM map for the RT3593 chipset
Three-chain devices are using a different
EEPROM layout than the rest of the chipsets.
Add a new map which describes the new layout
and use that for the RT3593 chipset.

The index values has been computed from the
EEPROM_EXT_* defines, which can be found in
the 'include/chip/rt3593.h' file in the
Ralink DPO_RT5572_LinuxSTA_2.6.0.1_20120629
driver.

379448fe34 rt2x00: rt2800lib: introduce rt2800_eeprom_word_index helper
Instead of assign the offset value to the
enum directly use a new helper function to
convert a rt2800_eeprom_word enum into an
index of the rt2x00_dev->eeprom array.

The patch does not change the existing
behaviour, but makes it possible to add
support for three-chain devices which are
using a different EEPROM layout.

3e38d3daf8 rt2x00: rt2800lib: introduce local EEPROM access functions
The patch adds rt2800 specific functions for
EEPROM data access and changes the code to use
these instead of the generic rt2x00_eeprom_*
variants.

To avoid functional changes, the new functions
are wrappers around the corresponding generic
rt2x00_eeprom_* routines for now. Functional
changes will be implemented in additional patches.

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."
