Use correct resolution by compat table. If dtb is not defined use default 9 bit mode.
11 bit detection is called if 9 bit mode is used.
Sysctl resolution variable is added to change resolution in case.
Some sensors didn't pull ACK while reading from nonexistent registers and it caused I2C
read error and detect failure, so now detect failure does not cause driver break.

Current Xen Processor driver will evaluate any Processor object on the
ACPI tables regardless of whether the processor is online or not.
Avoid doing so for processors that are not online, as evaluating
methods of processors that are not online could lead to accesses to
invalid memory, and in any case the data that the driver fetches from
the Processor ACPI object only makes sense for processors that are
online.
Note the CPU related data fetched from Xen using XENPF_get_cpuinfo
hypercall could be cached, I leave that as a future optimization.

BUS_PASS_SUPPORTDEV is semantically better than BUS_PASS_RESOURCE, since
it's a support device for dtsec, so only needs probed before dtsec, not
before interrupts.
Suggested by: manu
It's possible the MDIO device hasn't been and attached, or is incorrect
in the device tree so can't probe and attach. In this case,
ofw_bus_find_child_device_by_phandle() will fail, and return NULL.
Return an error from find_mdio() here to prevent the MAC from attaching,
rather than worry about a NULL pointer dereference later on when
accessing the PHY.
Along with _PSV, _HOT, and _CRT, ACPI supports the _CR3 threshold
which specifies a temperature above which a system should transition
to the S3 standby state.
On FreeBSD, this is more useful than _HOT, which specifies the S4
transition threshold temperature (since FreeBSD does not generally
support the S4 state), or, in many cases, _CRT, since after
transitioning to S3 the system can cool and then be resumed.

Rather than requiring a socket to be created as a TLS socket from the
get go, switch a TOE socket from "plain" TOE to TLS mode when a
receive key is added to the socket.
The firmware is only able to switch a "plain" TOE connection to TLS
mode if the head of the pending socket data is the start of a TLS
record, so the connection is migrated to TLS mode as a multi-step
process.
When TOE TLS RX is enabled, the associated connection's receive side
is frozen via a flag in the TCB. The state of the socket buffer is
then examined to determine if the pending data in the socket buffer
ends on a TLS record boundary. If so, the connection is migrated to
TLS mode and unfrozen. Otherwise, the connection is unfrozen
temporarily until more data arrives. Once more data arrives, the
receive queue is frozen again and rechecked. This continues until the
connection is paused at a record boundary. Any records received
before TLS mode is enabled are decrypted as software records.
Note that this removes the 'rx_tls_ports' sysctl. TOE TLS offload for
receive is now enabled automatically on existing TOE connections when
using a KTLS-aware SSL library just as it was previously enabled
automatically for TLS transmit. This also enables TLS offload for TOE
connections which enable TLS after passing initial data in the clear
(e.g. STARTTLS with SMTP).

It reports such datagrams with L4 integrity errors in IXGBE_XEC

To workaround the problem, let's ignore the XEC register value for

There's been a report recently of mbufs with data that crosses a page
boundary. It seems those mbufs are generated by the iSCSI target
system:
https://lists.xenproject.org/archives/html/xen-devel/2021-12/msg01581.html
In order to handle those mbufs correctly on netfront use the bus_dma
interface and explicitly request that segments must not cross a page
boundary. No other requirements are necessary, so it's expected that
bus_dma won't need to bounce the data and hence it shouldn't
introduce a too big performance penalty.
Using bus_dma requires some changes to netfront, mainly in order to
accommodate for the fact that now ring slots no longer have a 1:1
match with mbufs, as a single mbuf can use two ring slots if the data
buffer crosses a page boundary. Store the first packet of the mbuf
chain in every ring slot that's used, and use a mbuf tag in order to
store the bus_dma related structures and a refcount to keep track of
the pending slots before the mbuf chain can be freed.

Now that vtblk uses busdma, it keeps important information inside its

Add busdma-bypass paths. Since dumping writes contiguous blocks of
physical memory, vtblk doesn't need busdma in that case.
