Meeting details:
----------------
1. OFED 1.5.1 status:
These are the changes that were done to the source since OFED 1.5
release:
Kernel :
- rdma/cm: Fixup IPv6 support and IPv4 routing corner cases for RDMA CM
- RDS/TCP: Wait to wake thread when write space available
- RDS: use IB_CQ_VECTOR_LEAST_ATTACHED for cq's
- RDS: update copy_to_user state in tcp transport
- sdp: use IB_CQ_VECTOR_LEAST_ATTACHED for cq's
- sdp: make statistics per cpu and added statistics instead of prints
- Add support for RoCEE - as submitted to the kernel last week.

Userspace: 
- libmlx4, libibverbs - Add RoCEE support

Other changes that should be done:
- Open MPI update to rev. 1.4.1
- MVAPICH release update to 1.2
- Fix NFS-RDMA bugs and bring it to GA
- Bug fixes
- More OSes support - be prepared for RHEL 5.5 with back-ports - Ask
Doug Ledford if kernel is stable enough to start.
- Updated uDAPL package
- Support SDP on PPC64
- iSER support for distro

Still open:
- uMMU notifier kernel module - If it will be added to OFED then Open
MPI can add the code to support it. Need to check resources.
- SW implementation of RoCEE - need to check with SFW


2. OFED 1.5.1 Schedule:
I assume only 3 RCs:
- RC1 - Feb 2, 2010
- RC2 - Feb 16, 2010
- RC3 - Feb 24, 2010
- GA  - Mar 3, 2010

Reasonable, maybe RHEL 5.5 kernel will take more work. 

3. Update on OFED-RDMAoE branch:
The code is aligned with OFED 1.5 and the GA is expected tomorrow

4. OFED 1.6:
Open discussion on features, base kernel, main features, ...
Suggestion from Bill:
	- First datacenter focused release - Woody suggested to get a
written list and have a session in Sonoma on this.
	- Resolve Scalability issues
Other features (from SC09 OFA BOF):
	- SRIOV
	- Mellanox vnic
	- uMMU module (or any other kernel implementation)
	- Virtualization

5. Sonoma schedule:
Everybody should send input and session suggestions for Sonoma to Bill
Boas.
