Use nettest --{client,server}-dontroute to test the kernel behaviour
with TCP sockets having the SO_DONTROUTE option. Sending packets to a
neighbour (on link) host, should work. When the host is behind a
router, sending should fail.
Client and server sockets are tested independently, so that we can
cover different TCP kernel paths.
SO_DONTROUTE also affects the syncookies path. So ipv4_tcp_dontroute()
is made to work with or without syncookies, to cover both paths.

The type of the vlan_proto field is __be16.
And most users of the field use it as such.
In the case of setting or testing the field for the special VLAN_N_VID
value, host byte order is used. Which seems incorrect.
It also seems somewhat odd to store a VLAN ID value in a field that is
otherwise used to store Ether types.
Address this issue by defining BOND_VLAN_PROTO_NONE, a big endian value.
0xffff was chosen somewhat arbitrarily. What is important is that it
doesn't overlap with any valid VLAN Ether types.
I don't believe the problems described above are a bug because
VLAN_N_VID in both little-endian and big-endian byte order does not
conflict with any supported VLAN Ether types in big-endian byte order.

As not all ICE_TX_FLAGS_* fit in current 16-bit limited
tx_flags field that was introduced in the Fixes commit,
VLAN-related information would be discarded completely.
As such, creating a vlan and trying to run ping through
would result in no traffic passing.
Fix that by refactoring tx_flags variable into flags only and
a separate variable that holds VLAN ID. As there is some space left,
type variable can fit between those two. Pahole reports no size

When building the boot wrapper assembly files with clang after
commit 648a1783fe ("powerpc/boot: Fix boot wrapper code generation
with CONFIG_POWER10_CPU"), the following warnings appear for each file
built:
'-prefixed' is not a recognized feature for this target (ignoring feature)
'-pcrel' is not a recognized feature for this target (ignoring feature)
While it is questionable whether or not LLVM should be emitting a
warning when passed negative versions of code generation flags when
building assembly files (since it does not emit a warning for the
altivec and vsx flags), it is easy enough to work around this by just
moving the disabled flags to BOOTCFLAGS after the assignment of
BOOTAFLAGS, so that they are not added when building assembly files.
Do so to silence the warnings.

| SPI Sample Mode | SDM(bit13) | SDC(bit11) | Run Clock |

| normal sample | 1 | 0 | <= 24 MHz |
| delay half cycle sample | 0 | 0 | <= 40 MHz |

If a .handle_mask_sync() callback is provided it supersedes all
inbuilt handling of mask registers, and judging by the commit
69af4bcaa0 ("regmap-irq: Add handle_mask_sync() callback") it
is intended to completely replace all default IRQ masking logic.
The implementation has two minor inconsistencies, which can be
fixed without breaking compatibility:
(1) mask_base must be set to enable .handle_mask_sync(), even
though mask_base is otherwise unused. This is easily fixed
because mask_base is already optional.
(2) Unmask registers aren't accounted for -- they are part of
the default IRQ masking logic and are just a bit-inverted
version of mask registers. It would be a bad idea to allow
them to be used at the same time as .handle_mask_sync(),
as the result would be confusing and unmaintainable, so
make sure this can't happen.
