if_bnxt: Added support for mgmt interface for passthrough hwrms
Added support for application management interface. There are two types of commands supported:
1. Firmware IOCTLs: These ioctls are meant for firmware
consumption. Driver acts as a transport for these.
2. Driver only IOCTLs: These ioctls are meant for driver
consumption. Driver will serve these ioctls without sending them down
to firmware.

xdr: store chars consistently
Cast char's through unsigned char before storing as an integer in
xdr_char(), this ensures that the encoded form is consistently not
sign-extended following Open Solaris's example.
Prior to this change, platforms with signed chars would sign extend
values with the high bit set but ones with unsigned chars would not
so 0xff would be stored as 0x000000ff on unsigned char platforms and
0xffffffff on signed char platforms. Decoding has the same
result for either form so this is a largely cosmetic change, but it
seems best to produce consistent output.

LinuxKPI: add (skeleton) functions to make drivers compile
Add more functions to netdevice.h (netif_napi_add_tx() being the only
one implemented) and add platform_device.h and netlink.h in order to
make driver code compile.
The skeleton functions are used only in very limited scope and not at
all in our usage so far but add (invasive) #ifdef if removed.
Add pr_debug() calls to each of them in order to log a TODO (if DEBUG
compiled in) and someone should hit them in the future.

LinuxKPI: pci: add [linuxkpi_]pci_get_device()

Due to conflicts we cannot redefine it as we would normally do
in LinuxKPI so drivers have to be adjusted.

LinuxKPI: fix pci_alloc_irq_vectors() for MSI
pci_alloc_irq_vectors() is given a min and max vector value.
pci_enable_msi() will always succeed independent of these arguments as
it does not know about them. Further it will only ever allocate
1 "vector" not supporting any other amount.
So upfront check that (a) the available pci_msi_count() can satisfy the
requested minv and (b) given the pci_enable_msi() hard coded limit check
that minv is not larger than 1.
If we cannot satisfy either requirement return an error.
This fixes problems with drivers which check that the returned value
of allocated "vectors" will match their requests and only otherwise try
to fall back to ask for 1 or deal otherwise.

LinuxKPI: add kstrtou32_from_user() and mac_pton()
While here:
- fix an argument of kstrtouint_from_user() to correct signedness.
- make kstrtou32() call kstrtouint() to avoid duplication (keep inline
function)
Add kstrtou32_from_user() based on other examples in the file
making it a copy of the now fixed kstrtouint_from_user().
Also add a rudimentarily hacked up version of mac_pton() which is
leanient accepting non-well-formed input but so far only with ':'
separators. It does not seem to obviously belong to any networking
header file so add it here.
Both new functions are needed for debugfs support for iwlwifi hence
coming together in one commit.

Migrate the two functions from the header into the implementation file
in order to have access to more facilities and not to run into possible
allocation/locking/... problems in the future.
Implement cfg80211_{get,put}_bss currently doing malloc/free bits,
so hopefully the drivers get the calls right.
cfg80211_get_bss() sets up a lookup structure which may also take a
result (first hit wins) and calls ieee80211_scan_iterate() comparing
the various values in the iterator funcion. Some of the checks are
partially pointless (as it seems the drivers are not interested in
these parts [ANY] but we keep them for documentation purposes should
futher values arise in the future).
We currently only iterate over the first VAP which will do for now.

For the moment and the currently only consumer (mt76) add a simplified

Should we add more consumers or small (or large) objects would become a
