When IP addresses are used, the corresponding pkey is used. The issue this patch is addressing is the mapping of 'hostnames' to pkeys, as show in this ibacm_addr.cfg example: #Name device port pkey cst-lin0 mlx4_0 1 default cst-lin0-1 mlx4_0 1 default cst-lin0-2 mlx4_0 2 default Currently, 'default' is hard-coded to a pkey of 0xffff. The intent is to define a better default value. Kaike has suggested this be the new default: 1. Find the first non-management full-member pkey; 2. If it fails, find pkey 0xffff; 3. If pkey 0xffff is not available, use the first pkey. Is there better alternative for what default should be? Jason was suggesting use pkey[0], which seems less robust in theory, but is simple and may cover the vast majority of real use cases. The fewer cases where manual configuration is necessary, the fewer emails I receive, and the better off I am. :) - Sean
