2015-11-09scsi: use host wide tags by defaultChristoph Hellwig1-10/+0
This patch changes the !blk-mq path to the same defaults as the blk-mq I/O path by always enabling block tagging, and always using host wide tags. We've had blk-mq available for a few releases so bugs with this mode should have been ironed out, and this ensures we get better coverage of over tagging setup over different configs.

2015-06-19snic: driver for Cisco SCSI HBANarsimhulu Musini1-0/+1044
Cisco has developed a new PCI HBA interface called sNIC, which stands for SCSI NIC. This is a new storage feature supported on specialized network adapter. The new PCI function provides a uniform host interface and abstracts backend storage.
