Subject: [PATCH v3 0/6] ibmvfc: Protocol definition updates and new targetWWPN Support

Several Management Datagrams (MADs) have been reversioned to add a targetWWPN
field that is intended to better identify a target over in place of the scsi_id.
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 v3:
* addressed field naming consistency in Patches 2 & 5 in response to [brking]
* fixed commit log typos
* fixed bad rebase of Patch 4 such that it now compiles

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 target_wwpn field in v2 MADs and vfcFrame
  ibmvfc: advertise client support for targetWWPN using v2 commands
