which means that we rely on miibus to handle the allocation.
Add VSC8504 to the list of supported PHYs, as it is similar enough
to the VSC8501 that is already supported by this driver.

DP83822 is a 10/100 Texas Instruments PHY.
Link status change interrupts are supported by the driver,
however not all boards have the PHY interrupt wired.
Because of that if failure to allocate an IRQ is not treated as an error.

PHY drivers can than read the properties using device_get_property(9) API.
Resource(interrupt) allocation is also supported.
In order to enable this each NIC/switch driver will have to be modified,
because of how miibus is attached to the parent driver.

In some cases we might want to limit the max speed advertised below of what
the PHY is capable of.
This is usually the case when we connect 1G capable PHY to 100M MAC, or when
some exotic physical connection is used.
Add a new mii_maxspeed field to mii_softc and parse it in mii_phy_dev_attach.
Speed limit is normally located in DT.
The property is already parsed in mii_fdt.c, but its value still has to be
passed by the PHY driver.

- Health Status Event reporting from firmware (Use the new read-only

So, if we're processing a timeout, and we've sent an ABORT to the
firmware for that timeout, but not yet received the response from the
firmware, AND we get another timeout, we queue the timeout and freeze
the queue. However, when we've finally processed them all, we only
release the queue once. This causes all I/O to halt as the devq remains
frozen forever.
Instead, only freeze the queue when we start the process (eg set INRESET
on the target). This will allow the release when all the timed out I/Os
have finished ABORTing.

The current definition for the MMAP_RESOURCE ioctl was wrong as it
didn't copy back the result to the caller. Fix the definition and also
remove the bogus attempt to copy the result in the implementation.
Note such copy back is only needed when querying the size of a

Modern cryptographic random number generators can ingest arbitrarily
large amounts of non-random (or even maliciously selected) input
without losing their security.
Depending on the number of "boot entropy files" present on the system,
this can speed up the boot process by up to 1 second.

Modify the GPIO pins only on the Base-T cards and even there drive all
of them low instead of putting them in hi-z state. For the rest (this
is the common case), directly power off the PLLs of the high speed
serdes. This is the simplest method that does not involve or conflict
with the firmware but still works with all T4-T6 cards regardless of
what's plugged into the port.
This fixes a problem where the peer wouldn't always see a link down if
it is connected to the device using a -CR4 copper cable.

Recent firmwares have support for autonomous FEC selection and a "force"
knob to let the driver control this behavior (or not) in a fine grained
manner. This change adds a driver knob so that all the different ways of
configuring the link FEC can be exercised. Note that this controls the
internal driver/firmware interaction for link configuration and is not
meant for general use.

Recent firmwares have more leeway in FEC selection and there is a need
to track the FECs requested by the driver separately from the FEC in use
on the link. The existing dev.<port>.<inst>.fec sysctl can read both but
its behavior depends on the link state and it is sometimes hard to find
out what was requested when the link is up.
Split the fec sysctl into two (requested_fec and link_fec) to get access
to both pieces of information regardless of the link state.

Previously, sorele() always required the socket lock and dropped the
lock if the released reference was not the last reference. Many
callers locked the socket lock just before calling sorele() resulting
in a wasted lock/unlock when not dropping the last reference.
Move the previous implementation of sorele() into a new
sorele_locked() function and use it instead of sorele() for various
places in uipc_socket.c that called sorele() while already holding the
socket lock.
The sorele() macro now uses refcount_release_if_not_last() try to drop
the socket reference without locking the socket. If that shortcut
fails, it locks the socket and calls sorele_locked().

In a VF's configuration space, "memory space enable" is hard-wired to 0,
so the existing implementation always returns false. We need to read
the SR-IOV control register from the PF device to get the value of the
MSE bit.
Fix pci_bar_enabled() to read this register instead for VFs. I don't
see any way to access the PF's config space without a backpointer in the
pci device ivars, so I added one.
This fixes a regression where bhyve(8) fails to map the MSI-X table
after commit 7fa2335347 ("bhyve: Map the MSI-X table unconditionally
for passthrough") when a VF is passed through, since with that commit we
use PCIOCBARMMAP to map the table and that ioctl always fails for VFs
without this change. As a bonus, pciconf(8) now correctly reports the
enablement of BARs for VFs.
