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.

dcd7b3b269 Some RSS issues discovered by Adrian, missing header, variable
names fat fingered, incorrect hash config setup. Thanks :)

845a028fa3 Missing RSS support added, this fixes the build, but the code
in the RX side was complicated by recent changes and will need
some further tweaking.

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 This check has now now been
replaced by checking if "M_HASHTYPE_GET(m)" is different from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

b3f7259b25 Hide LRO code under #ifdef INET/INET6 to allow NOIP kernel to compile.
While the code comments indicate that LRO is currently only supported
for IPv4/TCP, we'll still compile it in for IPv6.

b555c6140d Properly place #ifdef INET and #ifdef INET6 around variable declarations
and code to make the code compile.

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.

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!
