Help to make iSER working

[Max Gurtovoy]

Hi Ben,

Our initial goal was to push the initiator driver to FreeBSD and we 
accomplished it.
You are welcome to report your benchmarks running iser and compare to 
tcp numbers.
Regarding plans for the target side, it's not on my plate for the near 
future (but obviously can be later on :)).
I'm not aware of other contributers plans.

Thanks,
Max.
