Hi Cheng,
Have you applied https://reviews.freebsd.org/D41170?
Can you also try 'ifconfig emXX -txcsum6' on the DUT?

I would like to gauge interest in holding a regular freebsd-net video

Greetings,
I have been looking into client networking issues in FreeBSD lately.
To summarize the situation, common NICs like Intel gigabit (e1000 aka

That class of processor has fairly limited memory bandwidth. An E5 v3 or

good use of available PCIe lanes with a single socket configuration can

Hi,
I was talking with gnn and kevans on IRC about the tcp testsuite
(https://github.com/freebsd-net/tcp-testsuite).
Currently we maintain this in ports, although the way the port is set
up doesn't make a lot of sense because the tests are stack specific
and we don't account for different FreeBSD
The per socket method is used at a large commercial CDN

I wasn’t aware of anyone desiring vf support for igb but I’ll take a look
at it for you if you can test -current with patches when I’m ready. My
motive is more to validate and refine the iflib functionality and this is a
good exercise.

iovctl worked at one point with ixgbe. I don’t recall if there is any way
to attach the vf directly if you do that but you can use ppt driver to pass
them into bhyve.

These are all pretty much known (to intel and NF/LLNW) issues with the
ixl driver. If you must run 11.1 you are best off just buying a
chelsio T580.
If you can run HEAD, or perhaps an eventual 11.3 MFC,

Cheng,
We run this in production at Limelight Networks (i.e toward a broad
spectrum of Internet hosts) and must to deal with some uncommon
network topology. There are currently some limitations as you point
out.
Like you say the signaling is not perfect and we do often clamp MSS
unnecessarily. T
The ixgb driver was used only briefly by one sub family of devices in
the first half of the 2000s. It's not a power efficient card with a
massive on board xenpak. The driver saw little specific (not
API/treewide stuff) maintenance post FreeBSD 5 in which the last real
intentional commit directly
A 3008 is an IT-mode card. I think the 3108 is an IR-mode only card.
I don't think dell does much to the firmwares, you can probably flash
them with Broadcom ones if needed.

For consideration, stable/11 will be supported until September 30, 2021
which provides a pretty long window to transition.

Hi,
The DPRINTF macro in netmap-fwd is defined as #define *DPRINTF*(_fmt,
args...) if (verbose) dprintf(_fmt, ## args)

The transition to iflib has exposed much jankiness in the Intel "shared
code" of the e1000 drivers. In particular, the locking contracts may not
align with FreeBSD locking primitives. I have boxes running the legacy

I think this would be a good candidate for iflib and can provide some
assistance from Matt and Sean if someone wants to try or we might get to it
eventually. Check out man 9 iflibdd. We had a lot of stability and

Right off the bat, FreeBSD doesn't really understand NUMA in any sufficient
capacity. Unfortunately at companies like the one I work at, we take that

us well and may ultimately be the best value but does nothing to address
