Analyze and fix the following issue in the Linux kernel code: [SCSI] ibmvfc: Better handle other FC initiators
Problem Details: The ibmvfc driver currently always sets the role of all rports to FC_PORT_ROLE_FCP_TARGET, which is not correct for other initiators. This can cause problems if other initiators are on the fabric when we then try to scan the rport for LUNs. Fix this by looking at the service parameters returned in the ...
