Main user-visible changes are related to tables:
* Tables are now identified by names, not numbers.
There can be up to 65k tables with up to 63-byte long names.
* Tables are now set-aware (default off), so you can switch/move
them atomically with rules.
* More functionality is supported (swap, lock, limits, user-level lookup,
batched add/del) by generic table code.
* New table types are added (flow) so you can match multiple packet fields at once.
* Ability to add different type of lookup algorithms for particular
table type has been added.
* New table algorithms are added (cidr:hash, iface:array, number:array and
flow:hash) to make certain types of lookup more effective.
* Table value are now capable of holding multiple data fields for
different tablearg users
Performance changes:
* Main ipfw lock was converted to rmlock
* Rule counters were separated from rule itself and made per-cpu.
* Radix table entries fits into 128 bytes
* struct ip_fw is now more compact so more rules will fit into 64 bytes
* interface tables uses array of existing ifindexes for faster match
ABI changes:
All functionality supported by old ipfw(8) remains functional.
Old & new binaries can work together with the following restrictions:
* Tables named other than ^\d+$ are shown as table(65535) in
ruleset in old binaries
Internal changes:.
Changing table ids to numbers resulted in format modification for
most sockopt codes. Old sopt format was compact, but very hard to
extend (no versioning, inability to add more opcodes), so
* All relevant opcodes were converted to TLV-based versioned IP_FW3-based codes.
* The remaining opcodes were also converted to be able to eliminate
all older opcodes at once
* All IP_FW3 handlers uses special API instead of calling sooptcopy*
directly to ease adding another communication methods
* struct ip_fw is now different for kernel and userland
* tablearg value has been changed to 0 to ease future extensions
* table "values" are now indexes in special value array which
holds extended data for given index
* Batched add/delete has been added to tables code
* Most changes has been done to permit batched rule addition.
* interface tracking API has been added (started on demand)
to permit effective interface tables operations
* O(1) skipto cache, currently turned off by default at
compile-time (eats 512K).
* Several steps has been made towards making libipfw:
* most of new functions were separated into "parse/prepare/show
and actuall-do-stuff" pieces (already merged).
* there are separate functions for parsing text string into "struct ip_fw"
and printing "struct ip_fw" to supplied buffer (already merged).
* Probably some more less significant/forgotten features

The VT-x code has the following types of MSRs:
- MSRs that are unconditionally saved/restored on every guest/host context
switch (e.g., MSR_GSBASE).
- MSRs that are restored to guest values on entry to vmx_run() and saved
before returning. This is an optimization for MSRs that are not used in
host kernel context (e.g., MSR_KGSBASE).
- MSRs that are emulated and every access by the guest causes a trap into

The flowdirector feature shares on-chip memory with other things
such as the RX buffers. In theory it should be configured in a way
that doesn't interfere with the rest of operation. In practice,
the RX buffer calculation didn't take the flow-director allocation
into account and there'd be overlap. This lead to various garbage
frames being received containing what looks like internal NIC state.
What _I_ saw was traffic ending up in the wrong RX queues.
If I was doing a UDP traffic test with only one NIC ring receiving
traffic, everything is fine. If I fired up a second UDP stream
which came in on another ring, there'd be a few percent of traffic
from both rings ending up in the wrong ring. Ie, the RSS hash would
indicate it was supposed to come in ring X, but it'd come in ring Y.
However, when the allocation was fixed up, the developers at Verisign
still saw traffic stalls.
The flowdirector feature ends up fiddling with the NIC to do various
attempts at load balancing connections by populating flow table rules
based on sampled traffic. It's likely that all of that has to be
carefully reviewed and made less "magic".
So for now the flow director feature is disabled (which fixes both
what I was seeing and what they were seeing) until it's all much
more debugged and verified.
Tested:

* (verisign) not sure on the NIC (but likely 82599), 100k-200k/sec TCP

This is the last major change in given branch.
Kernel changes:
* Use 64-bytes structures to hold multi-value variables.
* Use shared array to hold values from all tables (assume
each table algo is capable of holding 32-byte variables).
* Add some placeholders to support per-table value arrays in future.
* Use simple eventhandler-style API to ease the process of adding new
table items. Currently table addition may required multiple UH drops/
acquires which is quite tricky due to atomic table modificatio/swap
support, shared array resize, etc. Deal with it by calling special
notifier capable of rolling back state before actually performing
swap/resize operations. Original operation then restarts itself after
acquiring UH lock.
* Bump all objhash users default values to at least 64
* Fix custom hashing inside objhash.
Userland changes:
* Add support for dumping shared value array via "vlist" internal cmd.
* Some small print/fill_flags dixes to support u32 values.
* valtype is now bitmask of
<skipto|pipe|fib|nat|dscp|tag|divert|netgraph|limit|ipv4|ipv6>.
New values can hold distinct values for each of this types.
* Provide special "legacy" type which assumes all values are the same.

* Rewrite interface tables to use interface indexes
Kernel changes:
* Add generic interface tracking API:
- ipfw_iface_ref (must call unlocked, performs lazy init if needed, allocates
state & bumps ref)
- ipfw_iface_add_ntfy(UH_WLOCK+WLOCK, links comsumer & runs its callback to
update ifindex)
- ipfw_iface_del_ntfy(UH_WLOCK+WLOCK, unlinks consumer)
- ipfw_iface_unref(unlocked, drops reference)
Additionally, consumer callbacks are called in interface withdrawal/departure.
* Rewrite interface tables to use iface tracking API. Currently tables are
implemented the following way:
runtime data is stored as sorted array of {ifidx, val} for existing interfaces
full data is stored inside namedobj instance (chained hashed table).
* Add IP_FW_XIFLIST opcode to dump status of tracked interfaces
* Pass @chain ptr to most non-locked algorithm callbacks:
(prepare_add, prepare_del, flush_entry ..). This may be needed for better
interaction of given algorithm an other ipfw subsystems
* Add optional "change_ti" algorithm handler to permit updating of
cached table_info pointer (happens in case of table_max resize)
* Fix small bug in ipfw_list_tables()
* Add badd (insert into sorted array) and bdel (remove from sorted array) funcs
Userland changes:
* Add "iflist" cmd to print status of currently tracked interface
* Add stringnum_cmp for better interface/table names sorting

Netmap gets its own hardware-assisted virtual interface and won't take
over or disrupt the "normal" interface in any way. You can use both
simultaneously.
For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface
(note the 'n' prefix) in the hardware to accompany each cxl<N>
interface. These two ifnet's per port share the same wire but really
are separate interfaces in the hardware and software. Each gets its own
L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You
should run netmap on the 'n' interfaces only, that's what they are for.
With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port

Single port receive is at 33Mpps but this is very much a work in
progress. I expect it to be closer to 40Mpps once done. In any case
the current effort can already saturate multiple 10G ports of a T5 card

The CUSE library is a wrapper for the devfs kernel functionality which
is exposed through /dev/cuse . In order to function the CUSE kernel
code must either be enabled in the kernel configuration file or loaded
separately as a module. Currently none of the committed items are
connected to the default builds, except for installing the needed
header files. The CUSE code will be connected to the default world and
kernel builds in a follow-up commit.
The CUSE module was written by Hans Petter Selasky, somewhat inspired
by similar functionality found in FUSE. The CUSE library can be used
for many purposes. Currently CUSE is used when running Linux kernel
drivers in user-space, which need to create a character device node to
communicate with its applications. CUSE has full support for almost
all devfs functionality found in the kernel:
- kevents
- read
- write
- ioctl
- poll
- open
- close
- mmap
- private per file handle data
