From 5b50bf7e57c68316c1bda049d7b2c101ab7a8dcf Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Tue, 20 May 2014 13:28:11 +0300 Subject: Target/iser: Gracefully reject T10-PI enabled connect request if not supported commit 5f80ff8eccba50832dcc640ac89add4c7fced963 upstream. In case user chose to set T10-PI enable on the target while the IB device does not support it, gracefully reject the request.
