Hi Karan, > Add fnic_num in fnic.h to identify fnic in a multi-fnic environment. > Increment and set the fnic number during driver load in fnic_probe. > Replace the host number with fnic number in debugfs. I agree with Hannes. Everything else in the stack will be using the host number. Your change will make it harder to correlate a SCSI error message to an fnic driver instance. If you absolutely need an instance number I suggest you add it as an orthogonal value instead replacing the host. Also, we typically use an idr for enumerating things like this. -- Martin K.
