[PATCH 12/18] mpt3sas : Ported WarpDrive product SSS6200 support

From: Sreekanth Reddy
Date: Wed Sep 30 2015 - 11:52:41 EST

Ported below list of Warp drive specific patches
1. 'commit 0bdccdb0a090ad8dc5f851cad5e843244c410ee8
("mpt2sas: WarpDrive New product SSS6200 support added")',

2. 'commit 82a452581230b3ffc9d6475dffdb2568497b5fec
("mpt2sas: WarpDrive Infinite command retries due to wrong scsi command entry in MPI message")',

3. 'commit ba96bd0b1d4a4e11f23671e1f375a5c8f46b0fe7
("mpt2sas: Support for greater than 2TB capacity WarpDrive")',

4. 'commit 4da7af9494b2f98a1503a2634059300c3e4615e6
("mpt2sas: Do not retry a timed out direct IO for Warpdrive")',


5. 'commit daeaa9df92bd742f4e6d4d6039d689277a8e31bd
("mpt2sas: Avoid type casting for direct I/O commands")'.

Also set the mpt2_ioctl_iocinfo structure's adpter_type to
MPT3_IOCTL_INTERFACE_SAS3 for Gen3 HBA's
MPT2_IOCTL_INTERFACE_SAS2_SSS6200 for Warp Drive
MPT2_IOCTL_INTERFACE_SAS2 for other Gen2 HBA's
