From 32c30454507b4f5f00661ac12ddbcc150983b9ff Mon Sep 17 00:00:00 2001 From: Bhanu Prakash Gollapudi Date: Sun, 23 Oct 2011 23:23:57 -0700 Subject: [PATCH] [SCSI] bnx2fc: Handle SRR LS_ACC drop scenario When SRR LS_ACC is dropped, the driver was not issuing ABTS for SRR when it times out. Since the target received SRR, it was able to send the XFER_RDY and the the original IO request completed successfully. In this condition ABTS was not sent during bnx2fc_srr_compl(). Fix this by first checking for ELS timeout and issue ABTS before checking if original IO request is complete.
