Re: [PATCH v3 2/2][BNX2]: Add iSCSI support to BNX2 devices.

The sysfs bits related to the hba should be use one of the scsi sysfs 
facilities or if they are related to iscsi bits and are generic then 
through the iscsi hba

bnx2i needs 2 sysfs entries -
1. QP size info - this is used to size per connection shared data
structures to issue work requests to chip (login, scsi cmd, tmf, nopin)
and get completions from the chip (scsi completions, async messages,
etc'). This is a iSCSI HBA attribute
2. port mapper - we can be more flexible on classifying this as either
iSCSI HBA attribute or bnx2i driver global attribute
Can hooks be added to iSCSI transport class to include these?

Which ones were they exactly? I think JamesB wanted only common 
transport values in the transport class. If it is driver specific then 
it should go on the host or target or device with the scsi_host_template 
attrs.

It's a chicken & egg issue to put "port mapper" sysfs entry in scsi host
attributes. Application won't see sysfs unless initiator creates an
iSCSI session and driver can't create an iSCSI session without a tcp
port. I was wondering if there is a better way than using IOCTL in this
situation?
