Hi Moni.
I tried to use the mthca module parameter: for example i tried to change
the number of QPs.
I got several failures when i used the HCA 25204:

for example 512K QPs):

Hi Roland.
During the last night many tests failed in our regression (new failure
that appeared only during
the last night).
It seems that destroy an AH causes a seg fault, i reproduced it using
the ibv_ud_pingpong.

Hi Roland.
I opened bug 331 in the bugzilla with the following content:
When one tries to create a SRQ with many WR (> 16K WR), creation of the SRQ

If you wish, your SW can handle all of the HCAs: you can open a QP for

Hi all.
In
https://openib.org/svn/trunk/contrib/mellanox/ibtp/gen2/userspace/useraccess/multicast_test
there is
an example for using multicast messages over the verbs.
This test (for now) don't send any join message to the SA, it only
attach (and detach) the QP to the multicast group.
