Make sure that that byte is filled in according to the specification.

As T2 (SPARC64) is big-endian, which may not be tested sufficently, we had to fix some endian swap to make qla2x00t work good on it. The first fix is in q24_build_ctio_pkt(), loop_id from prm->cmd, which was generated by CPU, should be converted to little-endian when wrapped in pkt, which will be used by HBA ASIC. The second fix in qla2x_tgt_def.h, reorder the bit-order of structs' member, is an attempt in despair, cannot explain why, but it just works! Besides the programming skills, we cannot get QLogic FC HBA databook, and have little acknowledge about the driver, the fixes may need to be refined, so don't hold the comments :) Signed-off-by: Linwen Deng <linwendeng@gmail.com> ........ git-svn-id: http://svn.code.sf.net/p/scst/svn/branches/2.1.0.x@3974 d57e44dd-8a1f-0410-8b47-8ef2f437770f
