From b7ac4ab497e44cba75fb0e9e5afca06776518934 Mon Sep 17 00:00:00 2001 From: Ishai Rabinovitz Date: Sat, 17 Jun 2006 20:37:32 -0700 Subject: [PATCH] IB/srp: Handle DREQ events from CM Handle IB_CM_DREQ_ERROR and IB_CM_DREQ_RECEIVED events from the CM, instead of just printing "Unhandled CM event". In the case of DREQ_ERROR, just ignore the event -- a TIMEWAIT_EXIT will be generated also. For DREQ_RECEIVED, send a DREP in response to shut the connection down cleanly.
