[openib-general] [query]maximum no. of connections per session in iser initiator

[keshetti mahesh]

the max_conn(maximum no. of connections allowed per session ?)  field in iscsi_transport structure is not initialised at all while registering with the iSCSI layer in the iSER initiator code.
Is that variable is initialised to any default value? (like iSCSI/TCP has max_conn in iscsi_transport initialised to 1)

what are the maximum no. of connections allowed per session in iSER initiator?

regards,
Mahesh

 Yes, I was talking about this part only. 
 Isn't this variable is equivalent to the maximum no. of connections allowed per the session?
what is constraint for chosing this value as 8?

In the structure iscsi_transport there is a variable max_conn and it is set to 1
(In open-iscsi intiator  file name iscsi_tcp.c)
