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

All the LLQ related operations are unnecessary if the driver fails to

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

During media selection through ifconfig one might not specify

In that case the igc driver would default to full-duplex.
The problem with this approach is that e1000(em/igb) driver
defaults to half-duplex.
Because of that if one connects both NICs and sets media to
e.g. 100baseTX on both of them no link will be found.
Fix that by matching igc behaviour with what e1000 does.

Split the current FDT-only implementation up into an FDT and an
ACPI part reusing and sharing as much code as possible (thanks mw!).
This makes the Synopsis XHCI root hubs attach correctly on SolidRun's
HoenyComb instead of just the generic XHCI root and this means we
are also doing proper chip setup and applying the quirk needed there [1].
There is one problem with ACPI attachment in that it uses the generic
XHCI PNP ID. So we need to do extra checks in order to not claim
all xhci, which means we check for a known quirk to be present
in acpi_probe. Long term this isn't scaling and this was discussed
in SolidRun's Discord Channel in 2021 with the intend that "jnettlet"
will take this to a steering committee. Since then ACPI has kind-of
become a technology non grata (due to not getting changes into Linux
timely) so it is unclear if this will ever happen. If there will be
further hardware with dwc3/ACPI we should go and make sure this problem
gets solved.
