Rather than picking up Giant at the start of these sysctl handlers, push
acquiring Giant down a layer to protect walking the children and also
to add/delete children for the reconfigure.

Create a wrapper for newbus to take giant and for busses to take it too.
bus_topo_lock() should be called before interacting with newbus routines
and unlocked with bus_topo_unlock(). If you need the topology lock for
some reason, bus_topo_mtx() will provide that.

(Rest is from the README that came with the firmware)
Version : 1.26.4.0
Date : 12/02/2021
Fixes
-----
BASE:
- Fixed error on setting 25G speed on 100G copper with multiple FEC set in
firmware commands.
- Handle link of unknown optics modules by enabling module tx unconditionally.
- Fixed link not coming up for 25G CRS phys. Firmware incorrectly tried to
bring up the link in RS-FEC but as per IEEE spec, it must be BASER FEC.
- Fixed an issue where firmware doesn't automatically retry next FEC if driver
asks to bring up the link using RS-FEC and link doesn't come up.

With various firmware files used by graphics and wireless drivers
we are exceeding the current 32 character module name (file path
in kldxref) length.
In order to overcome this issue bump it to the maximum path length
for the next version.
To be able to MFC provide backward compat support for another version
of the struct as the offsets for the second half change due to the
array size increase.
MAXMODNAME being defined to MAXPATHLEN needs param.h to be
included first. With only 7 modules (or LinuxKPI module.h) not
doing that adjust them rather than including param.h in module.h [1].

The controller requires some custom logic to perform MMC tuning
and to later switch to HS400 mode. Implement it supplying mmcbr_tune
and sdhci_set_uhs_timing devmethods respectivly. Since the latter
is called unconditionally when the ios is updated we need to keep
track of the tuning state in sc and execute the HS400 switch logic
only when required.
Two HS200/HS400 related errata were implemented.
1. In HS400 modes the clock divisors are limited to 4, 8, 12.
Apply it by falling back to the closes, higher divider when needed.
2. Hardware tuning procedure can sometimes fails. If that is the case
fallback to the software tuning.

As `vqmmc-supply` is an optional Device Tree property, don't skip vccq
reconfiguration when the regulator is not specified. Instead, accept
voltage specified by the `voltage-ranges` property.
The actual voltage switch is done through a hw register in LS1028A.
Add errata flag for other boards, as they are not supported. Return
not supported error code when switching to 1.8V on affected platforms.

The e1000 drivers (em, lem, igb) are currently looking at the
iflib copies of the capabilities bitvectors (scctx->isc_capabilities
and scctx->isc_capenable) rather than the ifnet ones
(ifp->if_capabilities and ifp->if_capenable). However, the latter
are the ones that are actually updated by ifconfig and that should
be used by the drivers during interface operation. The former are
set by the driver on interface attach (for iflib internal use)
and should not be used anymore by the driver.
This patch fixes the e1000 driver to use the correct bitvectors.

In theory we can have multiple concurrent accesses to the MDIO bus,
e.g. link status check tick and ifconfig request.
In that case we need to make sure that all MDIO transaction are

Try to stop and destroy the dist only if the driver has been successfully
attached. Otherwise a kernel panic will be triggered from disk_destroy.
The issue was observed on a board that missed SPI clock description in DT.
Sweep over potentially unsafe calls to ifnet_byindex() and wrap them
in epoch. Most of the code touched remains unsafe, as the returned
pointer is being used after epoch exit. Mark that with a comment.
Validate the index argument inside the function, reducing argument
validation requirement from the callers and making V_if_index
private to if.c.

For AHCI attached devices, we report the location and identification
information of the AHCI controller that we're attached to. We also
don't reprot link speed in that case, since we can't get to the PCIe

When an NVME device is attached via a AHCI controller, we have no access
to its config space. So instead of information about the nvme drive
itself, return info about the AHCI controller as the next best
thing. Since the Intel Hardware RAID support looks at these values, this
likely is best.
