- We can't use a bus_hint_device_unit to wire the unit numbers of

Instead, when adding a child device, use a helper function much like
a bus_hint_device_unit method to look for wiring hints or to return
-1 to let the system choose a unit number. This function requires
an "at" hint for the port pointing to the nexus device and a "port"

hint.cxl.4.port="0"

r342466: bectl: use jail id as the default jail name for a boot environment
By default, bectl is setting the jail 'name' parameter to the boot
environment name, which causes an error when the boot environment name is
not a valid jail name. With the attached fix, when no name is supplied, the
default jail name will be the jail id - this is is the same behavior as the
jail command.
Additionally, this commit addresses two other bugs that prevented unjailing
in scenarios where the jail name does not match the boot environment name:
1. In 'bectl_locate_jail', 'mountpoint' is used to resolve the boot
environment path, but really 'mounted' should be used. 'mountpoint' is the
path where the zfs dataset will be mounted. 'mounted' is the path where
the dataset is actually mounted.
2. in 'bectl_search_jail_paths', 'jail_getv' would fail after the first
call. Which is fine, if the boot environment you're unjailing is the next
one up. According to 'man jail_getv', it's expecting name and value
strings. 'jail_getv' is being passed an integer for the lastjid, so amend
that to use a string instead.
Test cases have been amended to reflect the bugs found.

Detect sequential Write IOs and pass the hint that it is part of sequential
stream to help HBA Firmware do the Full Stripe Writes. For read IOs on
certain RAID volumes like Read Ahead volumes,this will help driver to
send it to Firmware even if the IOs can potentially be sent to
hardware directly (called fast path) bypassing firmware.
Design: 8 streams are maintained per RAID volume as per the combined
firmware/driver design. When there is no stream detected the LRU stream
is used for next potential stream and LRU/MRU map is updated to make this
as MRU stream. Every time a stream is detected the MRU map
is updated to make the current stream as MRU stream.

required Write IOs as Fast Path IOs (after the appropriate checks
allowing Fast Path to be used) to the appropriate physical drives
(translated from the OS logical IO) and wait for all Write IOs to complete.
Design: A write IO on RAID volume will be examined if it can be sent in
Fast Path based on IO size and starting LBA and ending LBA falling on to
a Physical Drive boundary. If the underlying RAID volume is a RAID 1/10,
driver issues two fast path write IOs one for each corresponding physical
drive after computing the corresponding start LBA for each physical drive.
Both write IOs will have the same payload and are posted to HW such that
replies land in the same reply queue.
If there are no resources available for sending two IOs, driver will send
the original IO from upper layer to RAID volume through the Firmware.
When both IOs are completed by HW, the resources will be released

Also, it only affects FreeBSD, because Linux skips the optimization
