Add a test for ensuring that the dst hint mechanism is used for
directed broadcast addresses.
This test relies on mausezahn for sending directed broadcast packets.
Additionally, a high GRO flush timeout is set to ensure that packets
will be received as lists.
The test determines if the hint mechanism was used by checking
the in_brd statistic using lnstat.

Some rtnetlink selftests assume the presence of ifconfig and iproute2
support for the `proto` keyword in `ip address` commands. These
assumptions can cause test failures on modern systems (e.g. Debian
Bookworm) where:
- ifconfig is not installed by default
- The iproute2 version lacks support for address protocol
This patch improves test robustness by:
- Skipping kci_test_promote_secondaries if ifconfig is missing
- Skipping do_test_address_proto if ip address help does not mention
proto
These changes ensure the tests degrade gracefully by reporting SKIP
instead of FAIL when prerequisites are not met, improving portability
across systems.

Kernel tries to be helpful and attach the XDP program in generic
mode if the driver has no BPF ndo at all. Since the xdp.py tests
all have "native" in their names this can be quite confusing.
Force native / "drv" attachment. Note that netdevsim re-uses
the generic handler as its "native" handler, so we'll maintain
the test coverage of the generic mode that way. No need to test
both explicitly, I reckon.

bootconfig: Fix negative seeks on 32-bit with LFS enabled
Commit 26dda57695 "tools/bootconfig: Cleanup bootconfig footer size
calculations" replaced some expressions of type int with the
BOOTCONFIG_FOOTER_SIZE macro, which expands to an expression of type
size_t, which is unsigned.
On 32-bit architectures with LFS enabled (i.e. off_t is 64-bit), the
seek offset of -BOOTCONFIG_FOOTER_SIZE now turns into a positive
value.
Fix this by casting the size to off_t before negating it.
Just in case someone changes BOOTCONFIG_MAGIC_LEN to have type size_t
later, do the same thing to the seek offset of -BOOTCONFIG_MAGIC_LEN.

When compiling with LLVM and CONFIG_LTO_CLANG is set, there exist many
objtool warnings "sibling call from callable instruction with modified
stack frame".
For this special case, the related object file shows that there is no
generated relocation section '.rela.discard.tablejump_annotate' for the
table jump instruction jirl, thus objtool can not know that what is the
actual destination address.
It needs to do something on the LLVM side to make sure that there is the
relocation section '.rela.discard.tablejump_annotate' if LTO is enabled,
but in order to maintain compatibility for the current LLVM compiler,
this can be done in the kernel Makefile for now. Ensure it is aware of
linker with LTO, '--loongarch-annotate-tablejump' needs to be passed via
'-mllvm' to ld.lld.
Before doing the above changes, it should handle the special case of the
relocation section '.rela.discard.tablejump_annotate' to get the correct
table size first, otherwise there are many objtool warnings and errors
if LTO is enabled.
There are many different rodata for each function if LTO is enabled, it
is necessary to enhance get_rodata_table_size_by_table_annotate().

ncdevmem tests that the kernel correctly rejects attempts
to deactivate queues with MPs bound.
Make the configure_channels() test support combined channels.
Currently it tries to set the queue counts to rx N tx N-1,
which only makes sense for devices which have IRQs per ring
type. Most modern devices used combined IRQs/channels with
both Rx and Tx queues. Since the math is total Rx == combined+Rx
setting Rx when combined is non-zero will be increasing the total
queue count, not decreasing as the test intends.
Note that the test would previously also try to set the Tx
ring count to Rx - 1, for some reason. Which would be 0
if the device has only 2 queues configured.
With this change (device with 2 queues):

dynptr for skb metadata behaves the same way as the dynptr for skb data
with one exception - writes to skb_meta dynptr don't invalidate existing
skb and skb_meta slices.
Duplicate those the skb dynptr tests which we can, since
bpf_dynptr_from_skb_meta kfunc can be called only from TC BPF, to cover the
skb_meta dynptr verifier checks.
Also add a couple of new tests (skb_data_valid_*) to ensure we don't
invalidate the slices in the mentioned case, which are specific to skb_meta
dynptr.

Looks like the 2msec sleep is not long enough. Make the sleep longer,
and then instead of second sleep wait for the thieving process to exit.
That way we can be sure it called recv() before us.
While at it also avoid trying to steal more than a record, this seems
to be causing issues in manual testing as well.
