Add auxiliary driver support.
An auxiliary device will be created if the hardware indicates
support for RDMA.
The bnxt_ulp_probe() function has been removed and a new
bnxt_rdma_aux_device_add() function has been added.
The bnxt_free_msix_vecs() and bnxt_req_msix_vecs() will now hold
the RTNL lock when they call the bnxt_close_nic()and bnxt_open_nic()
since the device close and open need to be protected under RTNL lock.
The operations between the bnxt_en and bnxt_re will be protected
using the en_ops_lock.
This will be used by the bnxt_re driver in a follow-on patch
to create ROCE interfaces.

ARCH_BCM2835
commit 8d820bc9d12b ("net: broadcom: Fix BCMGENET Kconfig") fixes the build
that contain 99addbe31f55 ("net: broadcom: Select BROADCOM_PHY for BCMGENET")
and enable BCMGENET=y but PTP_1588_CLOCK_OPTIONAL=m, which otherwise
leads to a link failure. However this may trigger a runtime failure.
Fix the original issue by propagating the PTP_1588_CLOCK_OPTIONAL dependency
of BROADCOM_PHY down to BCMGENET.

The 'imply' keyword does not do what most people think it does, it only
politely asks Kconfig to turn on another symbol, but does not prevent
it from being disabled manually or built as a loadable module when the
user is built-in. In the ICE driver, the latter now causes a link failure:
aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl':
ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config'

aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild':
This is a recurring problem in many drivers, and we have discussed
it several times befores, without reaching a consensus. I'm providing
a link to the previous email thread for reference, which discusses
some related problems.
To solve the dependency issue better than the 'imply' keyword, introduce a
separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver
can depend on if it is able to use PTP support when available, but works
fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are
then prevented from being built-in, the same way as with a 'depends on
PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick,
but that can be rather confusing when you first see it.
Since this should cover the dependencies correctly, the IS_REACHABLE()
hack in the header is no longer needed now, and can be turned back
into a normal IS_ENABLED() check. Any driver that gets the dependency
wrong will now cause a link time failure rather than being unable to use
PTP support when that is in a loadable module.
However, the two recently added ptp_get_vclocks_index() and
ptp_convert_timestamp() interfaces are only called from builtin code with
ethtool and socket timestamps, so keep the current behavior by stubbing
those out completely when PTP is in a loadable module. This should be
addressed properly in a follow-up.
As Richard suggested, we may want to actually turn PTP support into a
'bool' option later on, preventing it from being a loadable module
altogether, which would be one way to solve the problem with the ethtool
interface.

It should not have anything to do with code generation.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.

For compile-testing purposes, we don't really need this anyway,
as CONFIG_OF can be enabled on all architectures, and HAS_IOMEM
is present on all architectures we do meaningful compile-testing on

In order to break the hard dependency between the PTP clock subsystem and
ethernet drivers capable of being clock providers, this patch provides
simple PTP stub functions to allow linkage of those drivers into the
kernel even when the PTP subsystem is configured out. Drivers must be
ready to accept NULL from ptp_clock_register() in that case.
And to make it possible for PTP to be configured out, the select statement
in those driver's Kconfig menu entries is converted to the new "imply"
statement. This way the PTP subsystem may have Kconfig dependencies of
its own, such as POSIX_TIMERS, without having to make those ethernet
drivers unavailable if POSIX timers are cconfigured out. And when support
for POSIX timers is selected again then the default config option for PTP
clock support will automatically be adjusted accordingly.
The pch_gbe driver is a bit special as it relies on extra code in
drivers/ptp/ptp_pch.c. Therefore we let the make process descend into
drivers/ptp/ even if PTP_1588_CLOCK is unselected.

The bcma portion of the driver has been split off into a bcma specific
driver. This has been mirrored for the platform driver. The last
references to the bcma core struct have been changed into a generic
function call. These function calls are wrappers to either the original
bcma code or new platform functions that access the same areas via MMIO.
This necessitated adding function pointers for both platform and bcma to
hide which backend is being used from the generic bgmac code.

This patch ends up doing several things. First it updates the driver to
make use of the new unified UDP tunnel offload notifier functions. In
addition I updated the code so that we can work around the bits that were
checking for if VXLAN was enabled since we are now using a notifier based
setup.

This patch goes through and combines the notifiers for VXLAN and GENEVE
into a single function for each action. So there is now one combined
function for getting ports, one for adding the ports, and one for deleting
the ports.
I also went through and dropped the BNX2X VXLAN and GENEVE specific build
flags.

When CONFIG_GENEVE is built as a loadable module, and bnx2x is built-in,
we get this link error:
drivers/net/built-in.o: In function `bnx2x_open':
:(.text+0x33322): undefined reference to `geneve_get_rx_port'
drivers/net/built-in.o: In function `bnx2x_sp_rtnl_task':
:(.text+0x3e632): undefined reference to `geneve_get_rx_port'
This avoids the problem by adding a separate Kconfig symbol named
CONFIG_BNX2X_GENEVE that is only enabled when the code is
reachable from the driver.
This is the same trick that BNX2X does for VXLAN support, and
is similar to how I40E handles both.

The bgmac driver depends on BCMA_HOST_SOC, which is only used
when CONFIG_BCMA is enabled. However, it is a bool option and can
be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading
to an obvious link error:
drivers/built-in.o: In function `bgmac_init':
:(.init.text+0x7f2c): undefined reference to `__bcma_driver_register'
drivers/built-in.o: In function `bgmac_exit':
:(.exit.text+0x110a): undefined reference to `bcma_driver_unregister'
To avoid this case, we need to depend on both BCMA and BCMA_SOC,
as this patch does. I'm also trying to make the dependency more
readable by splitting it into three lines, and adding a COMPILE_TEST
alternative so we can test-build it in all configurations that
support BCMA.
The added dependency on FIXED_PHY addresses a related issue where
we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and
CONFIG_BGMAC=y.

VXLAN may be a loadable module, and this driver cannot be built-in
in that case, or we get a link error:
drivers/built-in.o: In function `__bnxt_open_nic':
drivers/net/ethernet/broadcom/bnxt/bnxt.c:4581: undefined reference to `vxlan_get_rx_port'
This adds a Kconfig dependency that ensures that either VXLAN is
disabled (which the driver handles correctly), or we depend on
VXLAN itself and disallow built-in compilation when VXLAN is
a module.

Broadcom ethernet driver for the new family of NetXtreme-C/E
ethernet devices.
v5:
- Removed empty blank lines at end of files (noted by David Miller).
- Moved busy poll helper functions to bnxt.h to at least make the
.c file look less cluttered with #ifdef (noted by Stephen Hemminger).
v4:
- Broke up 2 long message strings with "\n" (suggested by John Linville)
- Constify an array of strings (suggested by Stephen Hemminger)
- Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
- Use PCI_VDEVICE() to populate pci_device_id table for more compact
source.
v3:
- Fixed 2 more sparse warnings.
- Removed some unused structures in .h files.
v2:
- Fixed all kbuild test robot reported warnings.
- Fixed many of the checkpatch.pl errors and warnings.
- Fixed the Kconfig description (noted by Dmitry Kravkov).

Latest FW submission added some vxlan offload capabilities to our device.
This patch adds the ability to connect to the vxlan NDOs and configure
the UDP port associated with it in the HW.
The device would now be capable of performing RSS according to the
inner headers of the vxlan packets.

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.
