The KASSERT was originally added to ensure that the netmap Rx ring is
not NULL, however, it was checking for the opposite.

During probe the driver created a temporary buffer to which the value of
DEVICE_DESC constant was printed. This buffer was then copied to the
device structure using device_set_desc_copy. Since the value of this
string is exactly the same for every device using the ENA driver, using
sprintf is unnecessary, and device_set_desc can be used instead.

Copying ENI metrics was done in callout context, this caused the driver
to panic when sample_interval was set to a value other than 0, as the
admin queue call which was executed could sleep while waiting on
a condition variable. Taskqueue, unlike callout, allows for sleeping, so
moving the function to a separate taskqueue fixes the problem.
ena_timer_service is still responsible for scheduling the taskqueue.
Stop draining the callout during ena_up/ena_down. This was done to
prevent a race between ena_up/down and ena_copy_eni_metrics admin queue
calls. Since ena_metrics_task is protected by ENA_LOCK there is no
possibility of a race between ena_up/down and ena_metrics_task.
Remove a comment about locking in ena_timer_service. With ENI metrics
in a separate task this comment became obsolete.

The ena_com_config_dev_mode() function performs many LLQ related
calculations and sends an admin command to configure LLQ in the device.
All the LLQ related operations are unnecessary if the driver fails to
find LLQ memory bar.
Move LLQ memory bar allocation to separate helper function
ena_map_llq_mem_bar and execute this function before LLQ configuration.
If the LLQ memory bar cannot be allocated, then LLQ configuration is
skipped.

While ena_restore_device is called from the reset task, it can also be
called from other locations in the driver, for example in netmap
specific code. Move the reset completion logging to reset task, so it

When pf sends layer 2 traffic into dummynet it still marks IPv6 with
IPFW_ARGS_IPV6 (which dummynet translates to PROTO_V6). That in turn
results in it not matching the 'DIR_IN | PROTO_LAYER2' case, and
triggering the 'bad switch' error message.
Add extra cases for LAYER2 | PROTO_IPV6.

Do not assume that start_info will always be loaded at the highest

Add shm_remove_prison(), that removes all POSIX shared memory segments
belonging to a prison. Call it from prison_cleanup() so a prison
won't be stuck in a dying state due to the resources still held.
PR: 257555

Currently, when a jail starts dying, either by losing its last user
reference or by being explicitly killed,
osd_jail_call(...PR_METHOD_REMOVE...) is called. Encapsulate this
into a function prison_cleanup() that can then do other cleanup.
The field values are only valid when the ID_AA64PFR0_EL1.SVE or
ID_AA64PFR1_EL1.SME vields are non-zero. When this is not the case
the register is reserved as zero so is safe to read, but the SVEver
field will be incorrect so only print the decoded register when
the SVE or SME fields indicate it is valid.

On arm64 all registers have a name that encodes op0, op1, CRn, CRm, and
op2 that are used to encode the register in the instruction. As some
registers we need to access may not be supportedby older compilers, or
are only supported when specific extensions are enabled support this
alternative form.

Instead of returning EMSGSIZE pass the error code from fdallocn() directly
to userland. That would be EMFILE, which makes much more sense. This
error code is not listed in the specification[1], but the specification
doesn't cover such edge case at all. Meanwhile the specification lists
EMSGSIZE as the error code for invalid value of msg_iovlen, and FreeBSD
follows that, see sys_recmsg(). Differentiating these two cases will make
a developer/admin life much easier when debugging.
