ssh: update to OpenSSH 9.1p1
Release notes are available at https://www.openssh.com/txt/release-9.1
9.1 contains fixes for three minor memory safety problems; these have
lready been merged to the copy of OpenSSH 9.0 that is in the FreeBSD base
system.
* ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config
are now first-match-wins to match other directives. Previously
if an environment variable was multiply specified the last set
value would have been used. bz3438
* ssh-keygen(8): ssh-keygen -A (generate all default host key types)
will no longer generate DSA keys, as these are insecure and have
not been used by default for some years.
New features
------------
* ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum
RSA key length. Keys below this length will be ignored for user
authentication and for host authentication in sshd(8).
* sftp-server(8): add a "users-groups-by-id@openssh.com" extension
request that allows the client to obtain user/group names that
correspond to a set of uids/gids.
* sftp(1): use "users-groups-by-id@openssh.com" sftp-server
extension (when available) to fill in user/group names for
directory listings.
* sftp-server(8): support the "home-directory" extension request
defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps
a bit with the existing "expand-path@openssh.com", but some other
clients support it.
* ssh-keygen(1), sshd(8): allow certificate validity intervals,
sshsig verification times and authorized_keys expiry-time options
to accept dates in the UTC time zone in addition to the default
of interpreting them in the system time zone. YYYYMMDD and
YYMMDDHHMM[SS] dates/times will be interpreted as UTC if suffixed
with a 'Z' character.
Also allow certificate validity intervals to be specified in raw
seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This
is intended for use by regress tests and other tools that call
ssh-keygen as part of a CA workflow. bz3468
* sftp(1): allow arguments to the sftp -D option, e.g. sftp -D
"/usr/libexec/sftp-server -el debug3"
* ssh-keygen(1): allow the existing -U (use agent) flag to work
with "-Y sign" operations, where it will be interpreted to require
that the private keys is hosted in an agent; bz3429

Fix mpr(4) panic during a firmware update.
Issue Description:
The RequestCredits field of IOCFacts got changed between the Phase23
firmware to Phase24 firmware. So as part of firmware update operation,
driver has to free the resources & pools which are created with the Phase23
Firmware's IOCFacts data (i.e. during driver load time) and has to
reallocate the resources and pools using Phase24's IOCFacts data. Here
driver has freed the interrupts but missed to reallocate the interrupts and
hence config page read operation is getting timed out and controller is
going for recursive reinit (controller reset) operations and leading to
kernel panic.
Fix:
Reallocate the interrupts if the interrupts are disabled as part of

iflib: Introduce v2 of TX Queue Select Functionality
For v2, iflib will parse packet headers before queueing a packet.
This commit also adds a new field in the structure that holds parsed
header information from packets; it stores the IP ToS/traffic class
field found in the IPv4/IPv6 header.
To help, it will only partially parse header packets before queueing
them by using a new header parsing function that does less than the
current parsing header function; for our purposes we only need up to the
minimal IP header in order to get the IP ToS infromation and don't need
to pull up more data.

less-invasive method where none of the packet is parsed in iflib before
