[ofa-general] ipoib connected mode

[Michael Di Domenico]

5. On RedHat EL 4 up4, the IPOIB implementation is not spec-compliant:
   - ipoib multicast does not work
   - ipoib cannot interoperate between RHEL4U4 and other hosts. This is due to
     missing code in the kernel which was available in U3 and U5 but removed in
     U4. As a workaround, upgrade to RHEL4U5.


I found this blurb in the ipoib_release_notes file inside
ofed-1.2.5.1.  Does this mean that IPoIB does not work between a
RHEL4U4 and RHEL5 x86_64 machine?  I ask, because i have one of each
one with Ipath and one with Mthca and i can certainly talk between the
machines.

Is connected mode supported?
Do we have any performance benchmark numbers between two hosts running
over connected-mode?

Oh btw: this is OFED-1.2.5.1 on Mthca and Pathscale 2.2EA on Ipath
