- Switch to using 32b port/link capabilities in the driver. The 32b
format is used internally by firmwares > 1.16.45.0 and the driver will
now interact with the firmware in its native format, whether it's 16b
or 32b. Note that the 16b format doesn't have room for 50G, 200G, or
400G speeds.
- Add a bit in the pause_settings knobs to allow negotiated PAUSE
settings to override manual settings.
- Ensure that manual link settings persist across an administrative
down/up as well as transceiver unplug/replug.
- Remove unused is_*G_port() functions.

hashfilters. Two because the driver needs to look up a hashfilter by
its 4-tuple or tid.
A couple of fixes while here:
- Reject attempts to add duplicate hashfilters.
- Do not assume that any part of the 4-tuple that isn't specified is 0.
This makes it consistent with all other mandatory parameters that
already require explicit user input.

There used to be one control queue per adapter (the mgmtq) that was
initialized during adapter init and one per port that was initialized
later during port init. This change moves all the control queues (one
per port/channel) to the adapter so that they are initialized during
adapter init and are available before any port is up. This allows the
driver to issue ctrlq work requests over any channel without having to
bring up any port.

own region in the TCAM starting with T6, unlike previous chips where
they were in the same region as normal filters.
These filters "hit" before anything else in the LE's lookup. The exact
order is:
a) High priority filters
b) TOE's active region (TCAM and/or hash)
c) Servers (TOE hw listeners)
d) Normal filters

Add experimental knobs that allow the user to specify a default pktsize
and burstsize for traffic classes associated with a port:
dev.<ifname>.<instance>.tc.pktsize
dev.<ifname>.<instance>.tc.burstsize

- Ignore any type of TID where the start/end values are not in the
correct order. There are situations where the firmware isn't able to
reserve room for the number requested in the config file but doesn't
report a failure during configuration and instead sets end <= start.
- Track start/end in tid_tab and remove some redundant copies from
adapter->params.
- Move all the start/end and other read-only parameters to a quiet part
of tid_tab, away from the tid locks.

to be the same for both and the existing code worked by accident for
common configurations.

Start in "class" instead of "flow" mode. This eliminates the need to
specify an MTU, which is not available that early anyway. It also
allows the user to manually configure ch-rl rate limiting after attach.
This used to fail because ch-rl isn't supported if cl-rl "flow" mode is
configured.
Set all traffic classes to 1Gbps during initialization. The goal is to
start off with _any_ valid configuration and 1Gbps works even for
gigabit cards.

Track session objects in the framework, and pass handles between the
framework (OCF), consumers, and drivers. Avoid redundancy and complexity in
individual drivers by allocating session memory in the framework and
providing it to drivers in ::newsession().
Session handles are no longer integers with information encoded in various
high bits. Use of the CRYPTO_SESID2FOO() macros should be replaced with the
appropriate crypto_ses2foo() function on the opaque session handle.
Convert OCF drivers (in particular, cryptosoft, as well as myriad others) to
the opaque handle interface. Discard existing session tracking as much as
possible (quick pass). There may be additional code ripe for deletion.
Convert OCF consumers (ipsec, geom_eli, krb5, cryptodev) to handle-style
interface. The conversion is largely mechnical.
The change is documented in crypto.9.

- Add tracker argument to preemptible epochs
- Inline epoch read path in kernel and tied modules
- Change in_epoch to take an epoch as argument
- Simplify tfb_tcp_do_segment to not take a ti_locked argument,
there's no longer any benefit to dropping the pcbinfo lock
and trying to do so just adds an error prone branchfest to
these functions
- Remove cases of same function recursion on the epoch as
recursing is no longer free.
- Remove the the TAILQ_ENTRY and epoch_section from struct
thread as the tracker field is now stack or heap allocated
as appropriate.
