638000c0b6 Use public interfaces to manage the nested rate limit send tag.
Each TLS send tag in mlx5 contains a nested rate limit send tag.
Previously, the driver was calling internal functions to manage the
nested tag.  Calling free methods directly instead of m_snd_tag_rele()
leaked send tag references and references on the ifp.  Changes to use
the ifp methods for the nested tag for other methods are more cosmetic
but do simplify the code.

521eac97f3 Support hardware rate limiting (pacing) with TLS offload.
- Add a new send tag type for a send tag that supports both rate
  limiting (packet pacing) and TLS offload (mostly similar to D22669
  but adds a separate structure when allocating the new tag type).

- When allocating a send tag for TLS offload, check to see if the
  connection already has a pacing rate.  If so, allocate a tag that
  supports both rate limiting and TLS offload rather than a plain TLS
  offload tag.

- When setting an initial rate on an existing ifnet KTLS connection,
  set the rate in the TCP control block inp and then reset the TLS
  send tag (via ktls_output_eagain) to reallocate a TLS + ratelimit
  send tag.  This allocates the TLS send tag asynchronously from a
  task queue, so the TLS rate limit tag alloc is always sleepable.

- When modifying a rate on a connection using KTLS, look for a TLS
  send tag.  If the send tag is only a plain TLS send tag, assume we
  failed to allocate a TLS ratelimit tag (either during the
  TCP_TXTLS_ENABLE socket option, or during the send tag reset
  triggered by ktls_output_eagain) and ignore the new rate.  If the
  send tag is a ratelimit TLS send tag, change the rate on the TLS tag
  and leave the inp tag alone.

- Lock the inp lock when setting sb_tls_info for a socket send buffer
  so that the routines in tcp_ratelimit can safely dereference the
  pointer without needing to grab the socket buffer lock.

- Add an IFCAP_TXTLS_RTLMT capability flag and associated
  administrative controls in ifconfig(8).  TLS rate limit tags are
  only allocated if this capability is enabled.  Note that TLS offload
  (whether unlimited or rate limited) always requires IFCAP_TXTLS[46].

8836496815 Introduce support of SCSI Command Priority.
SAM-3 specification introduced concept of Task Priority, that was renamed
to Command Priority in SAM-4, and supported by all modern SCSI transports.
It provides 15 levels of relative priorities: 1 - highest, 15 - lowest and
0 - default.  SAT specification for SATA devices translates priorities 1-3
into NCQ high priority.

This change adds new "priority" field into empty spots of struct ccb_scsiio
and struct ccb_accept_tio of CAM and struct ctl_scsiio of CTL.  Respective
support is added into iscsi(4), isp(4), mpr(4), mps(4) and ocs_fc(4) drivers
for both initiator and where applicable target roles.  Minimal support was
added to CTL to receive the priority value from different frontends, pass it
between HA controllers and report in few places.

This patch does not add consumers of this functionality, so nothing should
really change yet, since the field is still set to 0 (default) on initiator
and not actively used on target.  Those are to be implemented separately.

I've confirmed priority working on WD Red SATA disks connected via mpr(4)
and properly transferred to CTL target via iscsi(4), isp(4) and ocs_fc(4).

While there, added missing tag_action support to ocs_fc(4) initiator role.

8a82be5044 Handle CPL_RX_DATA on active TLS sockets.
In certain edge cases, the NIC might have only received a partial TLS
record which it needs to return to the driver.  For example, if the
local socket was closed while data was still in flight, a partial TLS
record might be pending when the connection is closed.  Receiving a
RST in the middle of a TLS record is another example.  When this
happens, the firmware returns the the partial TLS record as plain TCP
data via CPL_RX_DATA.  Handle these requests by returning an error to
OpenSSL (via so_error for KTLS or via an error TLS record header for
the older Chelsio OpenSSL interface).

6b7ecdcd9d Re-enable receive flow control for TOE TLS sockets.
Flow control was disabled during initial TOE TLS development to
workaround a hang (and to match the Linux TOE TLS support for T6).
The rest of the TOE TLS code maintained credits as if flow control was
enabled which was inherited from before the workaround was added with
the exception that the receive window was allowed to go negative.
This negative receive window handling (rcv_over) was because I hadn't
realized the full implications of disabling flow control.

To clean this up, re-enable flow control on TOE TLS sockets.  The
existing TPF_FORCE_CREDITS workaround is sufficient for the original
hang.  Now that flow control is enabled, remove the rcv_over
workaround and instead assert that the receive window never goes
negative matching plain TCP TOE sockets.

f8e8a06d23 random(4) FenestrasX: Push root seed version to arc4random(3)
Push the root seed version to userspace through the VDSO page, if
the RANDOM_FENESTRASX algorithm is enabled.  Otherwise, there is no
functional change.  The mechanism can be disabled with
debug.fxrng_vdso_enable=0.

arc4random(3) obtains a pointer to the root seed version published by
the kernel in the shared page at allocation time.  Like arc4random(9),
it maintains its own per-process copy of the seed version corresponding
to the root seed version at the time it last rekeyed.  On read requests,
the process seed version is compared with the version published in the
shared page; if they do not match, arc4random(3) reseeds from the
kernel before providing generated output.

This change does not implement the FenestrasX concept of PCPU userspace
generators seeded from a per-process base generator.  That change is
left for future discussion/work.

10b1a17594 arc4random(9): Integrate with RANDOM_FENESTRASX push-reseed
There is no functional change for the existing Fortuna random(4)
implementation, which remains the default in GENERIC.

In the FenestrasX model, when the root CSPRNG is reseeded from pools due to
an (infrequent) timer, child CSPRNGs can cheaply detect this condition and
reseed.  To do so, they just need to track an additional 64-bit value in the
associated state, and compare it against the root seed version (generation)
on random reads.

This revision integrates arc4random(9) into that model without substantially
changing the design or implementation of arc4random(9).  The motivation is
that arc4random(9) is immediately reseeded when the backing random(4)
implementation has additional entropy.  This is arguably most important
during boot, when fenestrasX is reseeding at 1, 3, 9, 27, etc., second
intervals.  Today, arc4random(9) has a hardcoded 300 second reseed window.
Without this mechanism, if arc4random(9) gets weak entropy during initial
seed (and arc4random(9) is used early in boot, so this is quite possible),
it may continue to emit poorly seeded output for 5 minutes.  The FenestrasX
push-reseed scheme corrects consumers, like arc4random(9), as soon as
possible.

a3c41f8bfb Add "Fenestras X" alternative /dev/random implementation
Fortuna remains the default; no functional change to GENERIC.

Big picture:
- Scalable entropy generation with per-CPU, buffered local generators.
- "Push" system for reseeding child generators when root PRNG is
  reseeded.  (Design can be extended to arc4random(9) and userspace
  generators.)
- Similar entropy pooling system to Fortuna, but starts with a single
  pool to quickly bootstrap as much entropy as possible early on.
- Reseeding from pooled entropy based on time schedule.  The time
  interval starts small and grows exponentially until reaching a cap.
  Again, the goal is to have the RNG state depend on as much entropy as
  possible quickly, but still periodically incorporate new entropy for
  the same reasons as Fortuna.

Notable design choices in this implementation that differ from those
specified in the whitepaper:
- Blake2B instead of SHA-2 512 for entropy pooling
- Chacha20 instead of AES-CTR DRBG
- Initial seeding.  We support more platforms and not all of them use
  loader(8).  So we have to grab the initial entropy sources in kernel
  mode instead, as much as possible.  Fortuna didn't have any mechanism
  for this aside from the special case of loader-provided previous-boot
  entropy, so most of these sources remain TODO after this commit.

31deb3cc76 cxgbe(4): More fixes for the T6 FCS error counter.
r365732 was the first attempt to get an accurate count but it was
writing to some read-only registers to clear them and that obviously
didn't work.  Instead, note the counter's value when it is supposed to
be cleared and subtract it from future readings.

dev.<port>.stats.rx_fcs_error should not be serviced from the MPS
register for T6.

The stats.* sysctls should all use T5_PORT_REG for T5 and above.  This
must have been missed in the initial T5 support years ago.  Fix it while
here.

APM BIOS was relevant only to early laptops (approximately P166 or

this code has been untested for a long time (as far as I can
tell). The APM compat code in ACPI and the apm(8) command is not being
retired. Both of these items are still in use (apm(8) is more
scriptable than the replacement acpiconf, for the most part). This has
been commented out of i386 GENERIC since 2002. This code is not
relevant to any other port.

77af2b2c85 cxgbe(4): knobs to drop various kinds of undesirable frames on ingress.
These kind of drops come for free in the sense that they do not use the
filter TCAM or any other resource that wouldn't normally be used during
rx.  Frames dropped by the hardware get counted in the MAC's rx stats
but are not delivered to the driver.

hw.cxgbe.attack_filter
Set to 1 to enable the "attack filter".  Default is 0.  The attack
filter will drop an incoming frame if any of these conditions is true:
src ip/ip6 == dst ip/ip6; tcp and src/dst ip is not unicast; src/dst ip
is loopback (127.x.y.z); src ip6 is not unicast; src/dst ip6 is loopback
(::1/128) or unspecified (::/128); tcp and src/dst ip6 is mcast
(ff00::/8).

hw.cxgbe.drop_ip_fragments
Set to 1 to drop all incoming IP fragments.  Default is 0.  Note that
this drops valid frames.

hw.cxgbe.drop_pkts_with_l2_errors
Set to 1 to drop incoming frames with Layer 2 length or checksum errors.
Default is 1.

hw.cxgbe.drop_pkts_with_l3_errors

their own identical headers that stored the type that the
type-specific tag structures inherited from, so in practice it seems
drivers need this in the tag anyway.  This permits removing these
extra header indirections (struct cxgbe_snd_tag and struct
mlx5e_snd_tag).

In addition, this permits driver-independent code to query the type of
a tag, e.g. to know what type of tag is being queried via
if_snd_query.

d729904a4f Allow for interrupts on pl061 children
Add enough infrastructure for interrupts on children of the pl061 GPIO
controller. As gpiobus already provided these the pl061 driver also needs
to pass requests up the newbus hierarchy.

Currently there are no children that expect to configure interrupts, however
this is expected to change to support the ACPI Event Information interface.

74c781ed91 Refine the busdma template interface. Provide tools for filling in fields
that can be extended, but also ensure compile-time type checking.  Refactor
common code out of arch-specific implementations.  Move the mpr and mps
drivers to this new API.  The template type remains visible to the consumer
so that it can be allocated on the stack, but should be considered opaque.

7d5522e16a A major update to the ure driver.
This update adds support for:
HW VLAN tagging
HW checksum offload for IPv4 and IPv6
tx and rx aggreegation (for full gige speeds)
multiple transactions

In my testing, I am able to get 900-950Mbps depending upon
TCP or UDP, which is a significant improvement over the previous
91Mbps (~8kint/sec*1500bytes/packet*1packet/int).

aaa1fdb87b iwm: fix regression from r365419 (ieee80211_media_change())
In r365419 ieee80211_media_change() callers were updated to not longer
act on the obselete ENETRESET return code.
While in the old days iwm has done a stop/init cycle in these cases,
this was not executed since r193340.
As a consequence simplify iwm code as well by passing ieee80211_media_change()
right to ieee80211_vap_attach() as there is no more need for a local
implementation.

Summary of changes:

- Assorted bug fixes
- Support for newer versions of the device firmware
- Suspend/resume support
- Support for Lenient Link Mode for E82X devices (e.g. can try to link with
  SFP/QSFP modules with bad EEPROMs)
- Adds port-level rx_discards sysctl, similar to ixl(4)'s

This version of the driver is intended to be used with DDP package 1.3.16.0,
which has already been updated in a previous commit.

895c98cc29 Don't return errors from the cryptodev_process() method.
The cryptodev_process() method should either return 0 if it has
completed a request, or ERESTART to defer the request until later.  If
a request encounters an error, the error should be reported via
crp_etype before completing the request via crypto_done().

Fix a few more drivers noticed by asomers@ similar to the fix in
r365389.  This is an old bug, but went unnoticed since crypto requests
did not start failing as a normal part of operation until digest
verification was introduced which can fail requests with EBADMSG.

In r178354 with the introduction of multi-bss ("vap") support factoring
out started and with r193340 ieee80211_media_change() no longer returned
ENETRESET but only 0 or error.
As ieee80211(9) tells the ieee80211_media_change() function should not
be called directly but is registered with ieee80211_vap_attach() instead.

Some drivers have not been fully converted.  After fixing the return
checking some of these functions were simply wrappers between
ieee80211_vap_attach() and ieee80211_media_change(), so remove the extra
function, where possible as well.

1668d773a4 musb/allwinner: add support for configuring phy as well as device mode
At least on Orange Pi PC Plus even the host mode does not work without
enabling the phy and setting it to the host mode.

The driver will now parse dr_mode property and will try to configure
itself and the phy accordingly.
OTG mode is not supported yet, so it is treated as the device / peripheral
mode.

The phy is enabled -- powered on -- only for the host mode.

The device mode requires support from a phy driver, e.g., aw_usbphy on
Allwinner platform.
aw_usbphy does not support the device mode, so it cannnot work yet.
