IB/ipath: Indicate a couple of chip bugs to userspace
A couple of chip bugs in the iba6110 and in the iba6120 are not in more
recent chips. This first bug swaps two of the pioavail register
locations. In the second bug, the chip can sometimes forget to dma the
pio avail register to memory. We indicate the presence of these bugs
with runtime flags and we indicate the presence of the flags by bumping
the SWMINOR.
