I/O from userspace, capable of line rate at 10G, see

At this time I am bringing in only the generic code (sys/dev/netmap/
plus two headers under sys/net/), and some sample applications in
tools/tools/netmap. There is also a manpage in share/man/man4 [1]
In order to make use of the framework you need to build a kernel
with "device netmap", and patch individual drivers with the code
that you can find in
sys/dev/netmap/head.diff
The file will go away as the relevant pieces are committed to
the various device drivers, which should happen in a few days
after talking to the driver maintainers.
Netmap support is available at the moment for Intel 10G and 1G
cards (ixgbe, em/lem/igb), and for the Realtek 1G card ("re").
I have partial patches for "bge" and am starting to work on "cxgbe".
Hopefully changes are trivial enough so interested third parties
can submit their patches. Interested people can contact me
for advice on how to add netmap support to specific devices.

[1] In my opinion is a bad idea to have all manpage in one directory.
We should place kernel documentation in the same dir that contains
the code, which would make it much simpler to keep doc and code
in sync, reduce the clutter in share/man/ and incidentally is
the policy used for all of userspace code.
Makefiles and doc tools can be trivially adjusted to find the
manpages in the relevant subdirs.
based on Solarflare SFC9000 family controllers. The driver supports jumbo
frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO),
Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side
Scaling (RSS) using MSI-X interrupts.

FreeBSD" FreeBSD Foundation funded project.
- Add new man pages for the modular congestion control, Khelp and Hhook
frameworks (cc.4, cc.9, khelp.9 and hhook.9).
- Add new man pages for each available congestion control algorithm (cc_chd.4,
cc_cubic.4, cc_hd.4, cc_htcp.4, cc_newreno.4 and cc_vegas.4).
- Add a new man page for the Enhanced Round Trip Time (ERTT) Khelp module
(h_ertt.4).
- Update the TCP (tcp.4) man page to mention the TCP_CONGESTION socket option,
cross reference to cc.4 and remove references to the retired
"net.inet.tcp.newreno" sysctl MIB variable.

and updated comments in the usb_quirk.h header file.
The main purpose of this is to expose the quirks for ejecting 3G
modules. usb_modeswitch in Linux does a great job of collecting
information on these, and with the quirks module people can try out the
modeswitch config file entries on FreeBSD, hence the SCSI strings in the
man page.

These are: set to new value (=), addition (+=), subtraction (-=),

The driver is stub. It just creates device entry and feeds
reassembled packets from hardware into it.
If in future we would port wsmouse(4) from NetBSD, or make
sysmouse(4) to support absolute motion events, then the driver
can be extended to act as system mouse. Meanwhile, it just
presents a /dev/uep0, that can be utilized by X driver, that
I am going to commit to ports tree soon.
The name for the driver is chosen to be the same as in NetBSD,
however, due to different USB stacks this driver isn't a port.
