	drivers/net/ethernet/broadcom/bnx2x/bnx2x_stats.c

Small minor conflict in bnx2x, wherein one commit changed how
statistics were stored in software, and another commit
fixed endianness bugs wrt. reading the values provided by
the chip in memory.

Simon Graham 42bc0c9716 rtlwifi: Return correct failure code on error
Callers of rtl_pci_init expect zero to be returned on error. Returning
the error code leads to, amongst other things, divide by zero panics
attempting to use the ring size that is set to zero.

Tim Gardner 3d86b93064 rtlwifi: Fix PCI probe error path orphaned memory
Memory allocated by ieee80211_alloc_hw() will get orphaned
if any subsequent initializations fail.

Also don't pci_set_drvdata(pdev, NULL) until just before disabling
the PCI device. Functions called by rtl_deinit_core(hw) may eventually need
the context (when its actually implemented).

Larry Finger b0302aba81 rtlwifi: Convert to asynchronous firmware load
This patch addresses a kernel bugzilla report and two recent mail threads.

The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632,
which reports a udev timeout on boot.

The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/
linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a
suspend/resume cycle for rtl8192cu.

The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2)
concerned changes in udev that break drivers that delay while firmware is loaded
on modprobe.

This patch converts all rtlwifi-based drivers to use the asynchronous firmware
loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common
callback routine. Driver rtl8192se needs different handling of the firmware,
thus it has its own code.

macro, the macro is not defined for all routines that need it. By moving

Johannes Berg c1288b1278 mac80211: make beacon filtering per virtual interface
Due to firmware limitations, we may not be able to
support beacon filtering on all virtual interfaces.
To allow this in mac80211, introduce per-interface
driver capability flags that the driver sets when
an interface is added.
