03b04fd4f3 ixl: Fix mbuf hash type settings.
IPV6_EXs in RSS never mean fragment.  They mean:
"- Home address from the home address option in the IPv6 destination
   options header.  If the extension header is not present, use the
   Source IPv6 Address.
 - IPv6 address that is contained in the Routing-Header-Type-2 from
   the associated extension header.  If the extension header is not
   present, use the Destination IPv6 Address."

UDP_IPV4_EX is an invalid RSS hash type, which will be removed.

3820007146 ixl(4)/ixlv(4): Stop leaking every busdma entry in receive path
From Brett:

In short, busdma maps for received packets were not being unloaded in the
interrupt handler before the packets were passed up the network stack. The fix
was to add a busdma sync and unload for the two receive maps.

This bug is significant for certain busdma providers, for example IOMMUs,
where not unloading the maps means that 1) the IOMMU mappings that allow the
NIC to DMA the received packets into host memory stay open indefinitely,
potentially violating a desired security policy, and 2) resources such as
device address space addresses and host memory for bookkeeping are never freed.

Without an IOMMU or bounce buffering enabled for the ixl device, I don't think
adding these calls will have any significant performance impact. With the
IOMMU enabled, I have noticed a performance impact on the receive side, which
is expected.

5b83a512c1 ixl(4)/ixlv(4): Fix some busdma tags and improper map NULL.
Description from Brett:

"The busdma tags used to create mappings for the tx and rx rings did not have
the device's tag as parents, meaning that they did not respect the device's
busdma properties. The other tags used in the driver had their parents set
appropriately.

Also, the dma maps for each buffer in ixl_txeof() were being NULLed after
being unloaded, which is an error because those maps are then reused without
being recreated (I believe this also leaked resources since the maps were not
destroyed). Simply removing the line that sets the maps to NULL gives the
desired behavior. There does not seem to be a similar problem with ixl_rxeof().
Functions to free the tx and rx rings also NULL out the dma maps for each
buffer, but this seems okay because the maps are destroyed and not reused in
this case.

With these fixes, my ixl card seems to be working with the IOMMU enabled."

cb6b8299fd ixl(4): Update to 1.7.12-k
Refresh upstream driver before impending conversion to iflib.

Major new features:

- Support for Fortville-based 25G adapters
- Support for I2C reads/writes

(To prevent getting or sending corrupt data, you should set
dev.ixl.0.debug.disable_fw_link_management=1 when using I2C
[this will disable link!], then set it to 0 when done. The driver implements
the SIOCGI2C ioctl, so ifconfig -v works for reading I2C data,
but there are read_i2c and write_i2c sysctls under the .debug sysctl tree
[the latter being useful for upper page support in QSFP+]).

- Addition of an iWARP client interface (so the future iWARP driver for
  X722 devices can communicate with the base driver).
  - Compiling this option in is enabled by default, with "options IXL_IW" in
    GENERIC.

Several files use the internal name of `struct device` instead of
`device_t` which is part of the public API. This patch changes all
`struct device *` to `device_t`.

The remaining occurrences of `struct device` are those referring to the
Linux or OpenBSD version of the structure, or the code is not built on
FreeBSD and it's unclear what to do.

e84c2dea93 ixl(4): Fix potential driver interrupt setup issues and startup crash.
- Limit queue autoconfiguration to 8 queues to prevent the driver from
  requesting a large number of MSI-X vectors at boot.

- Fix potential kernel panic that occurs when the driver loads and cannot
  get all requested MSIX vectors. Instead, attach() will fail with an error.
  - Move taskqueue setup to later in attach() to prevent having to free
    taskqueues if some other error in attach() occurs.

b2bdc62a95 Refactor / restructure the RSS code into generic, IPv4 and IPv6 specific
bits.

The motivation here is to eventually teach netisr and potentially
other networking subsystems a bit more about how RSS work queues / buckets
are configured so things have a hope of auto-configuring in the future.

* net/rss_config.[ch] takes care of the generic bits for doing
  configuration, hash function selection, etc;
* topelitz.[ch] is now in net/ rather than netinet/;
* (and would be in libkern if it didn't directly include RSS_KEYSIZE;
  that's a later thing to fix up.)
* netinet/in_rss.[ch] now just contains the IPv4 specific methods;
* and netinet/in6_rss.[ch] now just contains the IPv6 specific methods.

This should have no functional impact on anyone currently using
the RSS support.

c25290420e Start process of removing the use of the deprecated "M_FLOWID" flag
from the FreeBSD network code. The flag is still kept around in the
"sys/mbuf.h" header file, but does no longer have any users. Instead
the "m_pkthdr.rsstype" field in the mbuf structure is now used to
decide the meaning of the "m_pkthdr.flowid" field. To modify the
"m_pkthdr.rsstype" field please use the existing "M_HASHTYPE_XXX"
macros as defined in the "sys/mbuf.h" header file.

This patch introduces new behaviour in the transmit direction.
Previously network drivers checked if "M_FLOWID" was set in "m_flags"
before using the "m_pkthdr.flowid" field. This check has now now been
replaced by checking if "M_HASHTYPE_GET(m)" is different from
"M_HASHTYPE_NONE". In the future more hashtypes will be added, for
example hashtypes for hardware dedicated flows.

"M_HASHTYPE_OPAQUE" indicates that the "m_pkthdr.flowid" value is
valid and has no particular type. This change removes the need for an
"if" statement in TCP transmit code checking for the presence of a
valid flowid value. The "if" statement mentioned above is now a direct
variable assignment which is then later checked by the respective
network drivers like before.

Additional notes:
- The SCTP code changes will be committed as a separate patch.
- Removal of the "M_FLOWID" flag will also be done separately.
- The FreeBSD version has been bumped.

f0188618f2 Fix multiple incorrect SYSCTL arguments in the kernel:
- Wrong integer type was specified.

- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.

- Logical OR where binary OR was expected.

- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.

- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.

- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.

- Updated "EXAMPLES" section in SYSCTL manual page.
