[rds-devel] [ofa-general] Re: Has anyone tried running RDS over 10GE / IWARP NICs ?

[Richard Frank]

This is all goodness -

I'm looking for something specific to what does and does not work with 
IWARP NICs in OFED today - perhaps a matrix comparing functionality of 
IB vs iWARP - so we know what not to do and or what to work around when 
running over IWARP NICS.

For now - we could probably just treat them as simple NICs and run RDS 
over TCP - that ought to at least  work..
