Subject[patch 73/85] [SCSI] mvsas: increase port type detection delay to suit Seagates 10k6 drive ST3450856SS 0003
2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Reinhard Nissl <rnissl@gmx.de>

commit ddccf307a3599e452804e228d8ed30fba578923e upstream.

I increased the delay step by step until loading of mvsas
reliably detected the drive 200 times in sequence. A much better
approach would be to monitor the hardware for some flag which
indicates that port detection has finished, but I do not have any
hardware documentation.
