[Qemu-devel] [PULL 1/4] tap: Use numbered tap/tun devices on all *BSD OS's

[Stefan Hajnoczi]

From: Brad Smith <brad@comstyle.com>

The following patch simplifies the *BSD tap/tun code and makes use of numbered
tap/tun interfaces on all *BSD OS's. NetBSD has a patch in their pkgsrc tree
to make use of this feature and DragonFly also supports this as well.

[Qemu-devel] [PULL 2/4] net: Rename send_queue to incoming_queue

[Stefan Hajnoczi]

From: Jan Kiszka <jan.kiszka@siemens.com>

Each networking client has a queue for packets that could not yet be
delivered to that client. Calling this queue "send_queue" is highly
confusing as it has nothing to to with packets send from this client but
to it. Avoid this confusing by renaming it to "incoming_queue".

[Qemu-devel] [PULL 3/4] e1000: add interrupt mitigation support

[Stefan Hajnoczi]

From: Vincenzo Maffione <v.maffione@gmail.com>

This patch partially implements the e1000 interrupt mitigation mechanisms.
Using a single QEMUTimer, it emulates the ITR register (which is the newer
mitigation register, recommended by Intel) and approximately emulates
RADV and TADV registers. TIDV and RDTR register functionalities are not
emulated (RDTR is only used to validate RADV, according to the e1000 specs).

RADV, TADV, TIDV and RDTR registers make up the older e1000 mitigation
mechanism and would need a timer each to be completely emulated. However,
a single timer has been used in order to reach a good compromise between
emulation accuracy and simplicity/efficiency.

The implemented mechanism can be enabled/disabled specifying the command
line e1000-specific boolean parameter "mitigation", e.g.

    qemu-system-x86_64 -device e1000,mitigation=on,... ...

For more information, see the Software developer's manual at
http://download.intel.com/design/network/manuals/8254x_GBe_SDM.pdf.

Interrupt mitigation boosts performance when the guest suffers from
an high interrupt rate (i.e. receiving short UDP packets at high packet
rate). For some numerical results see the following link
http://info.iet.unipi.it/~luigi/papers/20130520-rizzo-vm.pdf

[Qemu-devel] [PULL 4/4] vmxnet3: Eliminate __packed redefined warning

From: Brad Smith <brad@comstyle.com>

This eliminates a warning about __packed being redefined as exposed by the
vmxnet3 code. __packed is not used anywhere in the vmxnet3 code.

Sorry, I forgot to send you this feedback earlier.

This conflicts badly with a pull request from Michael Tsirkin that I
merged already.  Can you rebase against master and resubmit?

Thanks!

It would be nice if you can get the pcnet fix in your tree. For the ne2k
patch, as reported it might break the non-PCI version. I have to look at

Good.  I just wanted confirmation because I'm not up-to-speed on device
