[openib-general] [PATCH] defined struct ib_mw_bind

[Sean Hefty]

Here's a patch that defines ib_mw_bind.  Rather than defining yet another set of flags, I combined the MR, QP, and MW memory access flags together.  I will submit a second patch to update Roland's tree, to keep mthca in sync with this change.

The change has not been submitted yet.
