Hi Omar,
The only other way I can think of to verify whether the SRP initiator
and target drivers support iWARP is by loading the SRP drivers, loading
the iWARP driver, by configuring LIO + ib_srpt and by attempting to set
up a connection. However, I assume that's way more than what a _have()
test should do?
Bart.
