Further, a couple new MADs have been introduced to the protocol to be used for negotiation of channels/hw queues resources when the VIOS is using SLI-4 capable adapters. This patchset adds the new protocol definitions and implements support for using the new targetWWPN field and exposing the capability to the VIOS. This targetWWPN support is a prerequisuite for upcoming channelization/MQ support. changes in v2: Removed bug fixes to separate patchset Fixed up checkpatch warnings Tyrel Datwyler (6): ibmvfc: deduplicate common ibmvfc_cmd init code ibmvfc: add new fields for version 2 of several MADs ibmvfc: add helper for testing capability flags ibmvfc: add FC payload retrieval routines for versioned vfcFrames ibmvfc: add support for targetWWPN field in v2 MADs and vfcFrame ibmvfc: advertise client support for targetWWPN using v2 commands drivers/scsi/ibmvscsi/ibmvfc.c | 183 ++++++++++++++++++++++----------- drivers/scsi/ibmvscsi/ibmvfc.h | 28 ++++- 2 files changed, 145 insertions(+), 66 deletions(-)
