Copy two regions of registers and bigger DRAM region to the dump file.
Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

Add memory dump to the firmware crash data file which is provided to user space
via devcoredump interface. This makes it easier for firmware engineers to debug
firmware crashes.

Due to increased memory consumption the memory dump is disabled by default. To
enable it make sure that bit 3 is set in coredump_mask module parameter:

modprobe ath10k_core coredump_mask=0xffffffff

When RAMDUMP is enabled a buffer for the dump is allocated with vmalloc during
device probe. The actual memory layout is different in hardware versions and
the layouts are defined in coredump.c. The memory is split to regions and, to
get even finegrained control of what to copy, the region can split to smaller
sections as not all registers are readable (which could cause the whole system
to stall).

For memory dump support (it consumes quite a lot of memory) we need to control
what is exactly stored to the crash dump. Add a module parameter call
coredump_mask to do that. It's a bit mask of these values:

enum ath10k_fw_crash_dump_type {
	ATH10K_FW_CRASH_DUMP_REGISTERS = 0,
	ATH10K_FW_CRASH_DUMP_CE_DATA = 1,

	ATH10K_FW_CRASH_DUMP_MAX,
};

For example, if we only want to store CE_DATA we would enable bit 2:

modprobe ath10k_core coredump_mask=0x2

nfp: flower: add Geneve tunnel support

John Hurley says:

This patchset adds support for offloading the encap and decap of Geneve
tunnels to the NFP. In both cases, specifying well known port 6081 is a
requirement for rule offload.

Geneve firmware support has been recently added, so the patchset includes
the reading of a fw symbol that defines a bitmap of newly supported
features. Geneve will only be offloaded if the fw supports it. The new
symbol is added in fw r5646.

Geneve option fields are not supported as either a match or an action due
there current exclussion from TC flower. Because Geneve (as both a match
and action) behaves the same as other udp tunnels such as VXLAN, generic
functions are created that handle both Geneve and VXLAN. It is anticapated
that these functions will be modified to support options in future
patches.

The removal of an unused variable 'tun_dst_mask' is included as a separate
patch here. This does not affect functionality.

Also included are modifications to the test framework to check that the
new encap and decap features are functioning correctly.

Rather than adding new Geneve blocks, move the vxlan code to generic ipv4

Matches are only supported when specifically mentioning well known port
6081. Geneve tunnel options are not yet included in the match.

The tunnel dest IP is required for separate offload to the NFP. It is
already verified that a dest IP must be present and must be an exact
match in the flower rule. Therefore, we can just extract the IP from the
generated offload rule and remove the unused mask variable. The function
is then no longer required to return the IP separately.

Because tun_dst is localised to tunnel matches, move the declaration to
the tunnel if branch.
