[openib-general] [PATCH] change libipathverbs to use the new initialization convention

[Ralph Campbell]

The libibverbs.so.2 has a different device plug-in module
intialization convention from libibverbs.so.1.  This patch
updates the InfiniPath libipathverbs module to conform
to the new convention.
