1637c1b7eb rtlwifi: fix tm_trigger usage
While working on getting my rtl8821au driver in pretty shape for
inclusion, it is dicosvered that the tm_trigger flag is used only for
the first device using this driver.
This flag handles the thermal power management in the hardware.

To change this add a entry in sttruct rtl_dm, so each device can handle
is separately.

1277fa2ab2 rtlwifi: Remove the clear interrupt routine from all drivers
Several of these drivers have there TX randomly blocked for 3~5 seconds while
measuring tx throughput (iperf). The root couse happens in rtl_pci_flush().
The function uses a while-loop to wait for TX queue length to decrease to 0.
The TX queue length counts the number of packets that are queued in the driver.
The driver relys on the TX OK interrupt to return skb and reduce TX queue length.

The interrupt subroutine disables interupts, reads the interrupt registers, and
then clears the registers in the beginning of _rtl_pci_interrupt(). After all
interupts process are finished, the driver invokes enable_interrupt() to enable
interupts. This behavior is normal for an interrupt subroutine.

But enable_interrupt() invokes clear_interrupt() again. This unexpected interrupt
clearing may cleari me fresh TX OK interrupts. These missing interrupts cause TX
queue length to never reduce to 0i, which causes rtl_pci_flush() to be stuck in
unterminated while-loop.

This patch removes clear_interrupt() in enable_interrupt() to avoid this behavior.

b04096ff33 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Four minor merge conflicts:

1) qca_spi.c renamed the local variable used for the SPI device
   from spi_device to spi, meanwhile the spi_set_drvdata() call
   got moved further up in the probe function.

2) Two changes were both adding new members to codel params
   structure, and thus we had overlapping changes to the
   initializer function.

3) 'net' was making a fix to sk_release_kernel() which is
   completely removed in 'net-next'.

4) In net_namespace.c, the rtnl_net_fill() call for GET operations
   had the command value fixed, meanwhile 'net-next' adjusted the
   argument signature a bit.

This also matches example merge resolutions posted by Stephen
Rothwell over the past two days.

414b7e3b9c rtlwifi: rtl8192cu: Fix kernel deadlock
The USB mini-driver in rtlwifi, which is used by rtl8192cu, issues a call to
usb_control_msg() with a timeout value of 0. In some instances where the
interface is shutting down, this infinite wait results in a CPU deadlock. A
one second timeout fixes this problem without affecting any normal operations.

This bug is reported at https://bugzilla.novell.com/show_bug.cgi?id=927786.

df1404650c mac80211: remove support for IFF_PROMISC
This support is essentially useless as typically networks are encrypted,
frames will be filtered by hardware, and rate scaling will be done with
the intended recipient in mind. For real monitoring of the network, the
monitor mode support should be used instead.

Removing it removes a lot of corner cases.

 4) Many ipv4 FIB lookup optimizations from Alexander Duyck.

 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel

 6) Remove the ugly compat support in ARP for ugly layers like ax25,
    rose, etc.  And use this to clean up the neigh layer, then use it to
    implement MPLS support.  All from Eric Biederman.

 7) Support L3 forwarding offloading in switches, from Scott Feldman.

 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed
    up route lookups even further.  From Alexander Duyck.

 9) Many improvements and bug fixes to the rhashtable implementation,
    from Herbert Xu and Thomas Graf.  In particular, in the case where
    an rhashtable user bulk adds a large number of items into an empty
    table, we expand the table much more sanely.

10) Don't make the tcp_metrics hash table per-namespace, from Eric
    Biederman.

11) Extend EBPF to access SKB fields, from Alexei Starovoitov.

12) Split out new connection request sockets so that they can be
    established in the main hash table.  Much less false sharing since
    hash lookups go direct to the request sockets instead of having to
    go first to the listener then to the request socks hashed
    underneath.  From Eric Dumazet.

13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.

14) Support stable privacy address generation for RFC7217 in IPV6.  From
    Hannes Frederic Sowa.

15) Hash network namespace into IP frag IDs, also from Hannes Frederic
    Sowa.

16) Convert PTP get/set methods to use 64-bit time, from Richard
    Cochran.

cad737dfde rtlwifi: Add encryption argument in rtl_is_special_data for checking DHCP packet.
rtl8192cu can't connect to AP after physical reconnect.
according to dmesg, that problem's cause was DHCP timeout.

rtl_is_special_data function checks packet type for adjusting rate.
when that function is called from _rtl_rc_get_highest_rix, it can not
calculate offset correctly. so i add argument is_encn in rtl_is_special_data.
is_enc variable mean that iv header is added in skb parameter.

i test only rtl8192cu chipset. because i doesn't have other rtlwifi chipsets.

be0b5e6358 rtlwifi: Fix IOMMU mapping leak in AP mode
Transmission of an AP beacon does not call the TX interrupt service routine,
which usually does the cleanup. Instead, cleanup is handled in a tasklet
completion routine. Unfortunately, this routine has a serious bug in that it does
not release the DMA mapping before it frees the skb, thus one IOMMU mapping is
leaked for each beacon. The test system failed with no free IOMMU mapping slots
approximately one hour after hostapd was used to start an AP.

This issue was reported and tested at https://github.com/lwfinger/rtlwifi_new/issues/30.

0fa74a4be4 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	drivers/net/ethernet/emulex/benet/be_main.c
	net/core/sysctl_net_core.c
	net/ipv4/inet_diag.c

The be_main.c conflict resolution was really tricky.  The conflict
hunks generated by GIT were very unhelpful, to say the least.  It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().

So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged.  And this worked beautifully.

The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

0aef188a36 rtl8188ee: fix build break due to missing rtl_hal_pwrseqcmdparsing definition
I've been getting this error when building mainline kernels using
Fedora's config files:

    drivers/net/wireless/rtlwifi/rtl8188ee/hw.c: In function ‘_rtl88ee_init_mac’:
    drivers/net/wireless/rtlwifi/rtl8188ee/hw.c:853:2: error: implicit declaration of function ‘rtl_hal_pwrseqcmdparsing’ [-Werror=implicit-function-declaration]
      if (!rtl_hal_pwrseqcmdparsing(rtlpriv, PWR_CUT_ALL_MSK,
      ^
    cc1: some warnings being treated as errors
    scripts/Makefile.build:258: recipe for target 'drivers/net/wireless/rtlwifi/rtl8188ee/hw.o' failed

I'm not sure if this is the correct fix, but it does seem to allow the
build to complete. I suspect that this was broken by commit 34ed780a6a
(rtlwifi: Fix problems with building an allyesconfig). Most of the files
that removed the include of pwrseqcmd.h, added one for ../pwrseqcmd.h.
The rtl8188ee driver had it removed it but didn't add the include of the
file in the parent directory.

c8f0345586 rtlwifi: Improve handling of IPv6 packets
Routine rtl_is_special_data() is supposed to identify packets that need to
use a low bit rate so that the probability of successful transmission is
high. The current version has a bug that causes all IPv6 packets to be
labelled as special, with a corresponding low rate of transmission. A
complete fix will be quite intrusive, but until that is available, all
IPv6 packets are identified as regular.

This patch also removes a magic number.
