[ofa-general] [PATCH] mthca: increase INIT_HCA timeout

[akepner at sgi.com]

Here's a little patch we've been carrying along for a while.

If the num_qp module parameter is set higher than 2^19 or so, 
HCA initialization times out with EBUSY, e.g.:

ib_mthca: probe of 0031:01:00.0 failed with error -16

A 60 second timeout seems to be sufficient for the max number 
of QPs that the h/w can accomodate.
