From f62fe77ad26b9c89c2028d96709f0f28793fe6cd Mon Sep 17 00:00:00 2001 From: Bryan O'Sullivan Date: Thu, 28 Sep 2006 09:00:11 -0700 Subject: IB/ipath: Support multiple simultaneous devices of different types Prior to this change, the driver was not able to support a HT and PCIE card simultaneously present in the same machine.
