From 940fd304d233534038365f56d30c29ed7fd7416b Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Thu, 7 May 2015 16:34:23 -0500 Subject: iw_cxgb4: use wildcard mapping for getting remote addr info For listening endpoints bound to the wildcard address, we need to pass the wildcard address mapping to iwpm_get_remote_info() instead of the mapped address of the new child connection. Without this fix, and with iwarp port mapping enabled, each iw_cxgb4 connection that is spawned from a listening endpoint bound to the wildcard address, will generate an annoying dmesg entry about failing to find the remote address mapping info, and the connection state displayed in debugfs under /sys/kernel/debug/iw_cxgb4//eps will not have the peer's address/port mapping info. The connection still works though.
