a818292952 mac80211: convert rssi_callback() to event_callback()
We will be able to add more events, such as MLME events and
others. The low level driver may be interested in knowing
about these events to dump firmware data upon failures, or
to change parameters in case connection attempts fail etc...

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.

c406ea7c74 wil6210: Align Rx frames on 4*n+2 by having SNAP
For the networking code and for hardware network accelerators,
it is better to have IP header 4*n aligned. On the other side,
DMA on Rx path require buffer to be aligned on 4*n as well.
Having 14 bytes of Ethernet header, these 2 alignment
requests are in contradiction.

To solve this, order hardware offload block to not remove
SNAP header. This adds extra 6 bytes between addresses and
ethertype, making it 20 bytes total. This way, both buffer and
IP header are 4*n aligned. Remaining is only to remove SNAP
by shifting addresses 6 bytes. This involves data copying, so
this feature should be disabled unless required by the platform.

Module parameter "rx_align_2" (bool, default - false)
introduced to control this feature. Feature is completely disabled
when parameter is false.

cec94d8cf5 wil6210: fix check for FW responsiveness
"echo" used to be called when no firmware loaded to the NIC,
this causes error output.

Probe firmware with "echo" only after it returned "ready" event.

8fbb2e98fe cw1200: Fix suspend
The cw1200 driver implements suspend and resume callbacks and assigns them
to the suspend and resume fields of the device_driver struct. These
callbacks are never actually called by anything though.

Modify the driver to properly use dev_pm_ops so that the suspend function
is actually executed upon suspend and drop the empty resume function.

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.
