[ofa-general] rdma cm timeout option, was [iWARP issues]

[Kanevsky, Arkady]

Yes on first.
No on second yet.
Maybe for iWARP the only acceptable value will be "default"?
But this still feels that ULPs need to do something transport specific.
except for "default" case.
But implementing TCP style timeout for IB looks like overkill.
