From: Bart Van Assche bart.vanassche@wdc.com

commit a1ffa4670cb97ae3a4b3e8535d88be5f643f7c3b upstream.

Make sure that the initiator port GUID is stored in ch->ini_guid. Note: when initiating a connection sgid and dgid members in struct sa_path_rec represent the source and destination GIDs. When accepting a connection however sgid represents the destination GID and dgid the source GID.
