Hi Roland,
I see now that you've picked five of the patches from this series into
for-next, anything which needs clarification or fixup in the other
five patches?
Or.

Roland, could you add a CC to -stable so they can get to 3.8-stable too?

If IPoIB fails to look up a path record (eg if it tries during an SM
failover when one SM is dead but the new one hasn't taken over yet), the
driver ends up with a neighbour structure but no address handle (AH).
There's no mechanism to recover from this:

Ilya,
You can also take a look on the upstream trees for libibverbs and
libmlx4 maintained by Roland which have a debian dir, which you

Here's V3 of the IPoIB TSS/RSS patch series, basically its very similar to V2,
with fix to for one issue we stepped over while testing V2 and addressing of
feedback provided by Sean on the QP groups concept.
The concept of QP groups for TSS/RSS was introduced in the 2012 O
From: Shlomo Pongratz
RSS (Receive Side Scaling) TSS (Transmit Side Scaling, better known as
MQ/Multi-Queue) are common networking techniques which allow to use
contemporary NICs that support multiple receive and transmit descriptor
queues (multi-queue), see also Documentation/networking/scaling.

The number of RX/TX rings can now be get or changed using the ethtool

From: Shlomo Pongratz
This patch add RSS (Receive Side Scaling) and TSS (multi-queue transmit)
support for IPoIB. The RSS and TSS implementation utilizes the new QP
groups concept.
The number of RSS and TSS rings is a function of the number of cores,
and the low level driver capability to suppor

Depending on the mlx4 device capabilities, support the RSS IB device
capability, using Topelitz or XOR hash functions according to what
available with the HW. Support creating QP groups where all RX and TX
QPs have contiguous QP numbers.
