ixl(4): Fix NVM update API
Driver provides an interface for tools operating on adapters'
Non-Volatile Memory using SIOC(G|S)DRVSPEC ioctls. It allows
tools to issue Admin Queue commands to the firmware, which
may return an error code encoded as a negative integer.
The driver passed this negative integer as the return value
of the ioctl handler. This was causing issues because the FreeBSD
kernel reserves negative error codes in system calls for special
purposes such as restarting the handler or detecting incorrect
behavior in VFS operations. Simple remapping of negative values
to positive integers caused currently available tools to misbehave
and could break the NVM update process. Introduce a new API version,
which allows new versions of tools to detect the fixed driver.
Temporarily keep the old API, but issue a warning that tools need
to be updated.
Also refactor the code to use centralized cleanup and move the
debug message from the firmware earlier to make sure it is not masked

cxgbe(4): Fix netmap rx behavior with nm_split_rss
The driver should look for active queues and one potential default-queue
in both halves of the split instead of stopping at the first valid
default-queue.

em(4): fix capability bounds needed to access checksum context.
Ensure the offp capability bounds cover entire struct with checksum fields.
This is needed for CHERI systems to avoid bounds violation trap, as
otherwise offp allowed to dereference 4 bytes of csum_flags field only
so bzero failed.
Tested on ARM Morello.

vtnet: remove M_HASHTYPE when there is only one pair of rx/tx queue
Summary:
Doing so will let the upper layer know how to deal with software hash,
with benefits like inp_flowid can be set and m_pkthdr.flowid can be set
in output path.

[libc] Fix WIFSIGNALED and WIFSTOPPED for stopped and continued children (#235759)
WIFSIGNALED treated any non-zero termination signal as a signal, so it
was also true for a stopped child, whose low byte is 0x7f, and for a
continued one (0xffff). WIFSTOPPED masked with 0x7f instead of 0xff, so
it was also true for a continued child.
Make each macro true for exactly one kind of status, as glibc and musl
do, and add tests for exited, signalled, stopped and continued statuses.
AI disclosure: this patch was written with Claude Code. I reviewed the
change and ran the new test; it fails without the fix and passes with
it.

[NVPTX] Add patterns for mixed-precision mul (#232614)
This change adds support for mixed precision multiplication of `f32x2`
with a downconverted `f16x2` or `bf16x2` result, where the following
downconverting pattern:
```
%prod = llvm.nvvm.fmul{.ftz}.v2f32(%a, %b, rz)
%lo = extractelement <2 x float> %prod, i32 0
%hi = extractelement <2 x float> %prod, i32 1
%res = llvm.nvvm.ff2{f16x2/bf16x2}.rz(%hi, %lo, false)
```
is lowered to `mul{.ftz}.rz.{f16x2/bf16x2}.f32x2.f32x2`. These
instructions combine the conversion and the multiplication into one
instruction from `sm_107f` onwards.
The downconverting pattern is folded only when the `f32x2` result is
used solely by the conversion, avoiding generating an unnecessary
additional `mul` instruction.

[libc] Add TCP socket options to <netinet/tcp.h> (#236121)
This patch adds SOL_TCP and the TCP level socket option macros
(TCP_MAXSEG, TCP_CORK, TCP_KEEPIDLE, etc.), as well as the constants
used as values for TCP_REPAIR and TCP_REPAIR_QUEUE.
The values are Linux-specific, so I've moved them (along with the
existing TCP_NODELAY definition) out of the yaml file into a new
llvm-libc-macros header with an OS-specific subheader.
I've left out the options which need a struct to be useful (TCP_INFO,
TCP_MD5SIG, TCP_REPAIR_WINDOW, TCP_ZEROCOPY_RECEIVE, TCP_AO_*, etc.).
I'm leaving those for separate patch(es).
glibc and linux define the TCP_*_QUEUE constants as an enum. I've made
them macros instead, since they live in a macro header. This means our
header will not play nicely with <linux/tcp.h>, but that's true of
glibc's header as well.

tcp: Unifidef use of rss software hash in syncache
Ever since "d9c55b2e8cd6 rss: Enable portions of RSS globally.."
exposed the RSS software hashing functions, it has been possible
to use them without "ifdef RSS". Do so now in the syncache
so as to get flowids recorded.
Note that the use of the rss hash functions is conditional on IP versions,
so we must ifdef INET to ensure rss_proto_software_hash_v4() is available.
