[ofw] RE: patch 0/2 Add support for RDMAoEth to the low level driver

[Tzachi Dar]

We at Mellanox have started running our regression on this driver. u
So far we have found one bug (see attached patch at the end of this
mail).
 
xsigo have tested the code with our driver which includes following IB
support: 
1) CM support
2) MAD query
3) RC connection
4) FMR support.
 
We will continue to run with the attached patch and see if it solves all
the problems.
 
Thanks
Tzachi
 
p.s. I'm still looking for the correct const for
IB_WR_RDMA_READ_WITH_INV.

What level of testing has been applied to the RDMAoE patches to ensure
no side effects have been introduced into the IB stack operation?

First I would like to thank James Yang from Xsigo that actually did most
of the work, and brought RDMA over Ethernet to a working stage.
 
The first patch enables RDMAoEth to work. It includes code only for the
low level drivers.
The second patch is small changes needed in two small tests that I have
been using in order to test the work.
 
Thanks
Tzachi
