In smsc_phy_init function, when the driver was trying to reset PHY, it
didn't poll for the correct bit (BMCR_RESET) to be cleared. Instead, it
anded it with MII_BMCR (which is 0), so it just exited the loop.
This issue was fixed in Linux in commit d94609200069.

Previously, get_keyid() was returning the address of the receive key
instead of the transmit key when renegotiating the transmit key. This
could either hang the card (if a connection was only offloading TLS TX
and thus had a receive key address of -1) or cause the connection to
fail by overwriting the wrong key (if both RX and TX TLS were
offloaded).

- Microsemi SCSI driver for PQI controllers.
- Found on newer model HP servers.
- Restrict to AMD64 only as per developer request.
The driver provides support for the new generation of PQI controllers
from Microsemi. This driver is the first SCSI driver to implement the PQI
queuing model and it will replace the aacraid driver for Adaptec Series 9
controllers. HARDWARE Controllers supported by the driver include:
HPE Gen10 Smart Array Controller Family
OEM Controllers based on the Microsemi Chipset.

device-side (and only device-side) "virtual USB serial adapters" - the
ones you can get with an OTG-capable board - as consoles. It boils down
to adding the device name to kern.console sysctl, although doing that
requires jumping through some hoops. It doesn't change the actual
operation of those virtual devices. The point is to make it possible
for init(8) to recognize them as console devices and to launch getty(8)
for them, when configured as "onifconsole" in ttys(5). The point of
that, in turn, is to add such entries to the default ttys(5), so that
init(8) will launch gettys for device-side "virtual serial adapters",
but not for actual USB serial dongles.

We intend to remove support before FreeBSD 12 is branched. These are

The planned deprecation has been announced on -current and -stable; if
we receive feedback that the driver is still useful and we are able to
resolve the license issue this deprecation notice can be reverted.

This sysctl allows a deeper dive into the sleep abyss comparing to
debug.acpi.suspend_bounce. When the new sysctl is set the system will
execute the suspend sequence up to the call to AcpiEnterSleepState().
That includes saving processor contexts and parking APs. Then, instead
of actually entering the sleep state, the BSP will call resumectx() to
emulate the wakeup. The APs should get restarted by the sequence of
Init and Startup IPIs that BSP sends to them.

ACPI I/O port descriptors use _MIN and _MAX fields to specify the set
of allowable base (start) addresses for an I/O port resource along with
a _LEN field specifying the length. A fixed resource is supposed to be
encoded with _MIN == _MAX, but some buggy firmwares instead set _MAX to
the end of the fixed range. Relocating I/O ranges only make sense in
_PRS (possible resource settings), not in _CRS (current resource settings),
so if an I/O port range with _MAX set set to the end of the range is
present in _CRS, treat it as a fixed I/O port resource starting at
_MIN.

COP allows fine-grained control on whether to offload a TCP connection
using t4_tom, and what settings to apply to a connection selected for
offload. t4_tom must still be loaded and IFCAP_TOE must still be
enabled for full TCP offload to take place on an interface. The
difference is that IFCAP_TOE used to be the only knob and would enable
TOE for all new connections on the inteface, but now the driver will
also consult the COP, if any, before offloading to the hardware TOE.
A policy is a plain text file with any number of rules, one per line.
Each rule has a "match" part consisting of a socket-type (L = listen,
A = active open, P = passive open, D = don't care) and a pcap-filter(7)
expression, and a "settings" part that specifies whether to offload the
connection or not and the parameters to use if so. The general format
of a rule is: [socket-type] expr => settings
Example. See cxgbetool(8) for more information.
[L] ip && port http => offload
[L] port 443 => !offload
[L] port ssh => offload
[P] src net 192.168/16 && dst port ssh => offload !nagle !timestamp cong newreno
[P] dst port ssh => offload !nagle ecn cong tahoe
[P] dst port http => offload
[A] dst port 443 => offload tls
[A] dst net 192.168/16 => offload !timestamp cong highspeed
The driver processes the rules for each new listen, active open, or
passive open and stops at the first match. There is an implicit rule at
the end of every policy that prohibits offload when no rule in the
policy matches:
[D] all => !offload

The change makes the user and kernel address spaces on i386
independent, giving each almost the full 4G of usable virtual addresses
except for one PDE at top used for trampoline and per-CPU trampoline
stacks, and system structures that must be always mapped, namely IDT,
GDT, common TSS and LDT, and process-private TSS and LDT if allocated.
By using 1:1 mapping for the kernel text and data, it appeared
possible to eliminate assembler part of the locore.S which bootstraps
initial page table and KPTmap. The code is rewritten in C and moved
into the pmap_cold(). The comment in vmparam.h explains the KVA
layout.
There is no PCID mechanism available in protected mode, so each
kernel/user switch forth and back completely flushes the TLB, except
for the trampoline PTD region. The TLB invalidations for userspace
becomes trivial, because IPI handlers switch page tables. On the other
hand, context switches no longer need to reload %cr3.
copyout(9) was rewritten to use vm_fault_quick_hold(). An issue for
new copyout(9) is compatibility with wiring user buffers around sysctl
handlers. This explains two kind of locks for copyout ptes and
accounting of the vslock() calls. The vm_fault_quick_hold() AKA slow
path, is only tried after the 'fast path' failed, which temporary
changes mapping to the userspace and copies the data to/from small
per-cpu buffer in the trampoline. If a page fault occurs during the
copy, it is short-circuit by exception.s to not even reach C code.
The change was motivated by the need to implement the Meltdown
mitigation, but instead of KPTI the full split is done. The i386
architecture already shows the sizing problems, in particular, it is
impossible to link clang and lld with debugging. I expect that the
issues due to the virtual address space limits would only exaggerate
and the split gives more liveness to the platform.
