From c356afd48690775097507c37780ee17c0b0ea375 Mon Sep 17 00:00:00 2001 From: Joe Eykholt Date: Tue, 25 Aug 2009 14:02:17 -0700 Subject: [PATCH] [SCSI] libfc: discovery restart sequence error fix When an RSCN is received during fabric discovery, it restarts. After the restart, disc->seq_count was incremented, so when the first frame was received, it was considered "out of sequence". That left the state disc->active, preventing further discoveries. Change to advance the sequence count before parsing, so that it won't be changed after a potential restart.
