I am not entirely clear about this 1.2.c = 1.2.1 thing.<BR>
This is my understanding, please correct me if I am wrong - OFED-1.2 is the official<BR>
OFED release, OFED-1.2.c is a parallel line of development to support Connect X which<BR>
has been recently made available through a GIT tree on the OFED server. I presume, this<BR>
OFED-1.2.c would ultimately merge into the OFED-1.2 line of development to become the OFED-1.3 release.<BR>
<BR>
Also OFED-1.2.c does not seem like an incremental release of OFED-1.2<BR>
with some minor changes that could be equated with something like a OFED-1.2.1, considering the<BR>
changes for Connect X support and other kernel changes.<BR>
<BR>

<BR>
In the July 30th meeting minutes sent by Tziporet<BR>
(<A HREF="http://lists.openfabrics.org/pipermail/ewg/2007-July/004094.html">http://lists.openfabrics.org/pipermail/ewg/2007-July/004094.html</A>), it was<BR>
mentioned that the only release in August would be that of OFED-1.2.c. The<BR>
rationale given was that it would focus QA efforts and ensure wider test coverage.<BR>
<BR>
It is for this same reason that I have submitted these patches, so that we<BR>
can get wider test coverage of the changes to VNIC code as part of a complete OFED package.<BR>
<BR>
I hope I have made the intention behind submitting these patches clear.<BR>
<BR>
Also all of these patches are specific to VNIC and all changes are within the VNIC<BR>
driver and we have been testing them for some time now with the few previous releases<BR>
of OFED-1.2.c.<BR>
