Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley: "This patch set includes two large new drivers: mpt3sas (for the next gen fusion SAS hardware) and csiostor a FCoE offload driver for the Chelsio converged network cards (this includes some net changes which I've OK'd with DaveM). The rest of the patch is driver updates (qla2xxx, lpfc, hptiop, be2iscsi) plus a few assorted updates and bug fixes. We also have a Power Management rework in the Upper Layer Drivers preparatory to doing ACPI zero power optical devices, but the actual enabler is still being worked on. Signed-off-by: James Bottomley <JBottomley@Parallels.com>" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (72 commits) [SCSI] mpt3sas: add new driver supporting 12GB SAS [SCSI] scsi_transport_sas: add 12GB definitions for mpt3sas [SCSI] miscdevice: Adding support for MPT3SAS_MINOR(222) [SCSI] csiostor: remove unneeded memset() [SCSI] csiostor: Fix sparse warnings. [SCSI] qla2xxx: Display that driver is operating in legacy interrupt mode. [SCSI] qla2xxx: Dont clear drv active on iospace config failure. [SCSI] qla2xxx: Fix typo in qla2xxx driver. [SCSI] qla2xxx: Update ql2xextended_error_logging parameter description with new option. [SCSI] qla2xxx: Parameterize the link speed of hba rather than fcport. [SCSI] qla2xxx: Add 16Gb/s case to get port speed capability. [SCSI] qla2xxx: Move marking fcport online ahead of setting iiDMA speed. [SCSI] qla2xxx: Add acquiring of risc semaphore before doing ISP reset. [SCSI] qla2xxx: Ignore driver ack bit if corresponding presence bit is not set. [SCSI] qla2xxx: Fix typo in qla83xx_fw_dump function. [SCSI] qla2xxx: Add Gen3 PCIe speed 8GT/s to the log message. [SCSI] qla2xxx: Use correct Request-Q-Out register during bidirectional request processing [SCSI] qla2xxx: Move noisy Start scsi failed messages to verbose logging level. [SCSI] qla2xxx: Fix coccinelle warnings in qla2x00_relogin. [SCSI] qla2xxx: No fcport FC-4 type assignment in GA_NXT response. ...
