Remove unused and easy to misuse PNP macro parameter
Inspired by r338025, just remove the element size parameter to the
MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to
have correct pointer (or array) type. Since all invocations of the macro
already had this property and the emitted PNP data continues to include the
element size, there is no functional change.
Mostly done with the coccinelle 'spatch' tool:
$ cat modpnpsize0.cocci
@normaltables@
identifier b,c;
expression a,d,e;
declarer MODULE_PNP_INFO;
@@
MODULE_PNP_INFO(a,b,c,d,
-sizeof(d[0]),
e);
@singletons@
identifier b,c,d;
expression a;
declarer MODULE_PNP_INFO;
@@
MODULE_PNP_INFO(a,b,c,&d,
-sizeof(d),
1);
$ rg -l MODULE_PNP_INFO -- sys | \
xargs spatch --in-place --sp-file modpnpsize0.cocci
(Note that coccinelle invokes diff(1) via a PATH search and expects diff to
tolerate the -B flag, which BSD diff does not. So I had to link gdiff into
PATH as diff to use spatch.)

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Initially, only tag files that use BSD 4-Clause "Original" license.

socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself. Update all callers to use the return value.
With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.
NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices. Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.

there is an environment variable which shall initialize the SYSCTL
during early boot. This works for all SYSCTL types both statically and
dynamically created ones, except for the SYSCTL NODE type and SYSCTLs
which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to
be used in the case a tunable sysctl has a custom initialisation
function allowing the sysctl to still be marked as a tunable. The
kernel SYSCTL API is mostly the same, with a few exceptions for some
special operations like iterating childrens of a static/extern SYSCTL
node. This operation should probably be made into a factored out
common macro, hence some device drivers use this. The reason for
changing the SYSCTL API was the need for a SYSCTL parent OID pointer
and not only the SYSCTL parent OID list pointer in order to quickly
generate the sysctl path. The motivation behind this patch is to avoid
parameter loading cludges inside the OFED driver subsystem. Instead of
adding special code to the OFED driver subsystem to post-load tunables
into dynamically created sysctls, we generalize this in the kernel.
Other changes:
- Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask"
to "hw.pcic.intr_mask".
- Removed redundant TUNABLE statements throughout the kernel.
- Some minor code rewrites in connection to removing not needed
TUNABLE statements.
- Added a missing SYSCTL_DECL().
- Wrapped two very long lines.
- Avoid malloc()/free() inside sysctl string handling, in case it is
called to initialize a sysctl from a tunable, hence malloc()/free() is
not ready when sysctls from the sysctl dataset are registered.
- Bumped FreeBSD version to indicate SYSCTL API change.

In particular, don't check the value of the bus_dma map against NULL
to determine if either bus_dmamem_alloc() or bus_dmamap_load() succeeded.
Instead, assume that bus_dmamap_load() succeeeded (and thus that
bus_dmamap_unload() should be called) if the bus address for a resource
is non-zero, and assume that bus_dmamem_alloc() succeeded (and thus
that bus_dmamem_free() should be called) if the virtual address for a
resource is not NULL.
In many cases these bugs could result in leaks when a driver was detached.

new 1Gb server controller chip that will be going into production
soon.
BCM5725 combines MAC with triple-speed PHY, a Network Controller
Sideband Interface (NC-SI) and on-chip memory buffer in a single
device. BCM5725 has an Application Processing Engine (APE) that is
capable of on-chip management and offloading features. BCM5725
supports high-precision clock, time stamp registers for
receive/transmit packets and programmable trigger inputs and
watchdog timeouts. These new features are not yet supported by
bge(4).

The read DMA request logic operation is based on having sufficient
available space in the transmit data buffer (TXMBUF) before a read
DMA can be requested. There are four read DMA channels that use
the TXMBUF, and the logic checks if the available free space in the
TXMBUF is large enough for all the data in the four Send Buffers
for which buffer descriptors have been fetched. The Enable_Request
signal is asserted only if the free TXMBUF space is larger than the
sum of the four DMA length registers. The power-up default value
of BGE_RDMA_LSO_CRPTEN_CTRL register bit 25 (bit 21 on BCM5720) is
zero, which selects the DMA length registers to connect to the
input of the adder block. The DMA length registers are
asynchronously reset following BCM5719/BCM5720 power-up, and due to
the lack of synchronous deassertion of the length registers reset
signal these resisters may contain uninitialized values following
the reset deassertion.
In the case of the failure the uninitialized DMA length register
values added up to more than the TXMBUF size, which prevented the
assertion of the Enable_Request signal and any subsequent read DMA
to start. This lockup condition is the root cause of failing to
generate any transmit traffic.
To workaround the issue, select alternate output of multiplexers
and transmit the first four Ethernet frames. This overwrites the
DMA length registers with valid values.

Reporting link status in driver has a side-effect that makes mii(4)
check current link status. mii(4) will call link status change
callback when it sees link state change. Normally this wouldn't
have problems. However, ASF/IPMI firmware can actively access PHY
regardless of driver's running state such that reporting link
status for not-running interface can generate meaningless link
UP/DOWN messages.
This change also makes dhclient think driver got a valid link
regardless of link establishment so it will bypass dhclient's
initial link status check. I think that wouldn't be issue
though.

Fix the IPMI regression by sending BGE_FW_DRV_STATE_UNLOAD to
ASF/IPMI firmware in driver attach phase. Sending heartheat to
ASF/IPMI is enabled only after upping interface so
setting driver state to BGE_FW_DRV_STATE_START in attach phase
broke IPMI access.
While I'm here, add NVRAM arbitration lock before performing
controller reset. ASF/IPMI firmware may be able to access the NVRAM
while controller reset is in progress. Without the arbitration
lock before resetting the controller, ASF/IPMI may not initialize
properly.

static const struct bzzt_type {
[...list of members...]
} const bzzt_devs[] = {

The second const is unnecessary, as arrays cannot be modified anyway,
and if the elements are const, the whole thing is const automatically
(e.g. it is placed in .rodata).
I have verified this does not change the binary output of a full kernel
build (except for build timestamps embedded in the object files).
