[ofa-general] [PATCH 4/8] IB/ipath - Change default number of kernel send buffers

[Arthur Jones]

From: Ralph Campbell <ralph.campbell at qlogic.com>

The default calculation for the number of send buffers to allocate
to the kernel was too high for the PCIe version of the chip thus
leaving fewer than desired send buffers for user MPI applications.
