From c762608bf75f792dcaf3658338189b9970951704 Mon Sep 17 00:00:00 2001 From: Joe Eykholt Date: Tue, 25 Aug 2009 14:02:33 -0700 Subject: [SCSI] libfc: fix: empty zone causes endless discovery retries. On some switches, an empty zone causes GPN_FT to be rejected with reason 9 (unable) explanation 7 (FC-4 types not registered), which causes discovery to be retried endlessly. Treat this as just an empty response and consider discovery complete.
