This pertains exclusively to the set/restore functionality that we offer,
where any changes made by loader.conf previously will be effectively removed
upon reload of the configuration. We don't currently have a need to export
these, so don't bother.
Not all systems use efifb; pull hw.vga.textmode and choose a good console
mode instead if it's set to something non-zero. This is basically a revival
of the code that used to live in boot1, but instead rebased onto this
different way of doing mode selection in loader.efi.
Interestingly enough, the regression that was previously introduced where
GOP would not reflect the console setting does not seem to exist when
console mode selection is done here. I've not done any investigation as to
why this is the case. Nevertheless, boot1.efi is still not the best place to
do mode selection.
This fixes an avoidable EINVAL when the user tries to disable AN after
the port is initialized but l1cfg doesn't have a valid speed to use.

UEFI booting requires an EFI System Partition (ESP). On most storage devices
this will be in a specific partition type. To allow booting from CD/ISO
filesystems, UEFI will look for an ESP in the form of a FAT filesystem image
embedded in the image. Historically FreeBSD has added one of these to its
amd64 ISO images but marked it as simply another i386 boot image. Luckily for
us most UEFI implementations are rather forgiving and work this out for us.
This change adds the ability to mark a boot image as being a UEFI image. It
also modifies our ISO generation to use this marking for the UEFI image we
embed.

Since the FW can be shared between PCI functions it is common that
more than one health poll will detected a failure, this can lead to
multiple resets.
The solution is to use a FW locking mechanism using semaphore space to
provide a way to synchronize between functions. The FW semaphore is
acquired via config cycle access. First the VSEC gateway must be
acquired, then the semaphore can be locked by writing a value to it
and confirmed it's locked by reading the same value back. The process
in the same to free the semaphore, except the value written should be
zero.

Some mlx5 adapter firmware allows the driver to reset the firmware in
the event of an error. When a software reset is issued on any physical
function all PFs enter reset state. This is a recoverable condition.
The existing recovery flow was designed to allow the recovery of a
VF after a PF driver reload. This patch expands the scope of that
flow to recover PFs or VFs after a SW reset has been issued.
When a software reset is issued the following occurs:
1. The NIC interface mode is set to SW_RESET (7) while the reset is in
progress.
2. Once the reset completes the NIC interface mode is set to NIC
disabled (1).
After the reset has been issued (added in a subsequent patch) the
health poll for other functions will detect that the NIC interface
state has been set to disabled. This will cause it to enter the
existing recovery flow. If the PCI is still working (meaning it
doesn't return 0xff on all reads) it means recovery can proceed
immediately instead of waiting 60 seconds.
The error detetion has also been refactored to avoid incorrect or
misleading log messages.

Forwarded packets passed through PFIL_OUT, which made it difficult for
firewalls to figure out if they were forwarding or producing packets. This in
turn is an issue for pf for IPv6 fragment handling: it needs to call
ip6_output() or ip6_forward() to handle the fragments. Figuring out which was
difficult (and until now, incorrect).
Having pfil distinguish the two removes an ugly piece of code from pf.
Introduce a new variant of the netpfil callbacks with a flags variable, which
has PFIL_FWD set for forwarded packets. This allows pf to reliably work out if
a packet is forwarded.

The mps(4) and mpr(4) drivers and hardware handle T10 Protection
Information, which is a system of checksums and guard blocks to protect
data while it is being transferred and while it is on disk. It is also
known as T10 DIF. For more details, see section 4.22 of the SBC-4 spec.
Supporting Type 2 protection requires using 32 byte CDBs, and filling in
the fields in those CDBs. We don't yet support that in the da(4) driver.
Type 1 and Type 3 protection don't require that, and can be handled by
the mps(4)/mpr(4) driver's code and firmware without any additional
input from the da(4) driver.
If a drive has Type 2 protection enabled (you frequently see this with
SAS drives shipped from Dell), don't set the various EEDP fields in the
mps(4)/mpr(4) driver command fields. Otherwise, you wind up with errors
like this that would otherwise make no sense:
(da9:mpr0:0:18:0): READ(10). CDB: 28 00 00 00 00 00 00 02 00 00
(da9:mpr0:0:18:0): CAM status: SCSI Status Error
(da9:mpr0:0:18:0): SCSI status: Check Condition
(da9:mpr0:0:18:0): SCSI sense: ILLEGAL REQUEST asc:20,0 (Invalid command operation code)
(da9:mpr0:0:18:0):
(da9:mpr0:0:18:0): Field Replaceable Unit: 0
(da9:mpr0:0:18:0): Command Specific Info: 0

(da9:mpr0:0:18:0): Error 22, Unretryable error
In other words, what kind of strange SAS hard drive doesn't support a
standard 10 byte SCSI READ command? In this case, one that has Type 2
protection enabled.
We can revisit this when we put Type 2 protection support in the da(4)
driver, but for now this will help people who put Type 2 formatted drives
in a system and wonder what in the world is going on.
