Subject: [PATCH] ibacm/libacm.c: Use IPv4 rather than IPv6 for ACM server communication
Date: Thu, 05 Apr 2012 16:05:24 -0400	[thread overview]
Message-ID: <4F7DFB04.2030803@dev.mellanox.co.il> (raw)


When both IPv4 and IPv6 are running, getaddrinfo indicates IPv6
rather than IPv4 and that currently causes a failure to connect to
the ACM server. Fix is to set the address family in the hint to
getaddrinfo to IPv4.
