bc8b78d393 Add native netmap support to ixl.
Preliminary tests indicate 32 Mpps on tx, 24 Mpps on rx
with source and receiver on two different ports of the same 40G card.
Optimizations are likely possible.
The code follows closely the one for ixgbe so i do not
expect stability issues.

Hardware kindly supplied by Intel.

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.

393c4bb1ba Intel I40E driver updates:
if_ixl to version 1.3.0, if_ixlv to version 1.2.0
	- Major change in both drivers is to add RSS support
	- In ixl fix some interface speed related issues, dual
	  speed was not changing correctly, KR/X media was not
	  displaying correctly (this has a workaround until a
	  more robust media handling is in place)
	- Add a warning when using Dell NPAR and the speed is
	  less than 10G
	- Wrap a queue hung message in IXL_DEBUG, as it is non-fatal,
	  and without tuning can display excessively

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 This check has now now been
replaced by checking if "M_HASHTYPE_GET(m)" is different from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.

cf3c0c32d2 Ensure that ixl_flush() uses a defined register on VFs
In some code that is shared between the ixl(4) and ixlv(4) drivers,
a macro hard-coded a register offset that was not valid on ixlv devices.
Fix this by having each driver define a variable that contains the correct
offset.

d94ca7cf07 Revert r270808, which were changes to common code (i40e_alloc.h).
Rather than #define-ing common code function calls to OS-dependent
ones, make the osdep versions match the common code expectations,
adjust the FreeBSD specific code to use those, and remove the
#defines.

In the FreeBSD specific code, use "i40e_mem_reserved" for the
now expected but unused argument to i40e_allocate_dma_mem().

Give the function seems to be slightly mixed with csum and tso,
make it non-fatal if we try to setup thing on a kernel without IP
support.  In practise the printf on the console will probably still
make your machine unhappy.

ff21e856ec First try on fixing some more compile errors without actually testing:
- use proper __FreeBSD_version check and more importantly check for __am64__
  to be defined.  Whether the FreeBSD(_version) checks are needed is a
  different question.
- cast uint64_t to uintmax_t and use %jx for printing.

Note: there are more values that could be printed in that status function
	but leave that for the future;  printf doesn't seem to be the right
	way to do it anyway.
Note: there is more breakage related to i40e_allocate_dma*() having
	conflicting declarations, so more fixes to come.

61ae650d55 Update to the Intel Base driver for the Intel XL710 Ethernet Controller Family
- It was decided to change the driver name to if_ixl for FreeBSD
	- This release adds the VF Driver to the tree, it can be built into
	  the kernel or as the if_ixlv module
	- The VF driver is independent for the first time, this will be
	  desireable when full SRIOV capability is added to the OS.
	- Thanks to my new coworker Eric Joyner for his superb work in
	  both the core and vf driver code.

Enjoy everyone!
