From 677cb9722a64d3f944d3e374e0ef1bb0e45644b5 Mon Sep 17 00:00:00 2001 From: John Baldwin Date: Thu, 20 May 2021 17:16:23 -0700 Subject: [PATCH] cxgbe tom: Free pending iSCSI mbufs on connection shutdown. If an iSCSI connection is shutdown abruptly (e.g. by a RST from the peer), pending iSCSI PDUs and page pod work requests can be in the ulp_pduq when the final CPL is received indicating the death of the connection.
