From a91eb042e1bacdc61a2ca5cb184aa99c24ed5cdb Mon Sep 17 00:00:00 2001 From: Jenny Derzhavetz Date: Wed, 24 Feb 2016 19:23:58 +0200 Subject: iser-target: Fix identification of login rx descriptor type commit b89a7c25462b164db280abc3b05d4d9d888d40e9 upstream. Once connection request is accepted, one rx descriptor is posted to receive login request. This descriptor has rx type, but is outside the main pool of rx descriptors, and thus was mistreated as tx type.
