There is an OFED-1.5 based package with RDMAoE support. The pacage can
be downloaded from
http://www.openfabrics.org/downloads/OFED/ofed-rdmaoe-1.5-daily/

The sources can be found here:
ssh://git.openfabrics.org/home/eli/scm/ofed-1.5/kernel.git/linux-2.6.git rdmaoe
ssh://git.openfabrics.org/home/eli/scm/ofed-1.5/user.git/libibverbs.git rdmaoe
ssh://git.openfabrics.org/home/eli/scm/ofed-1.5/user.git/libmlx4.git rdmaoe


The following tests have been converted:
libibverbs/examples:
ibv_rc_pingpong
ibv_uc_pingpong
ibv_uc_pingpong
ibv_srq_pingpong

The package was tested and works with RDS:
rds-ping
rds-stress

rdma_cm tests:
mckey
ucmatose

SDP sockets work: iperf was used to check this.

devices supported:
ConnectX Ethernet devices
ConnectX VPI devices

Fw version:
For RDMAoE to work, FW 2.6.900 and newer must be used.

Geneal notes:
1. RDMAoE requires verbs consumers to use GRH. libibverbs/examples
tests have been modify to accept "-g <remote gid>"
2. Formerly, IB links were usually 2K. Now RDMAoE links are likely to
show 1K; UD applications should be aware of that since UD message size
is limited by MTU.
