From b8457606d95f219052cbcf07bd54c24c4290cd49 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 23 Dec 2019 10:28:44 -0500 Subject: SUNRPC: call_connect_status should handle -EPROTO The xprtrdma connect logic can return -EPROTO if the underlying device or network path does not support RDMA. This can happen after a device removal/insertion. - When SOFTCONN is set, EPROTO is a permanent error. - When SOFTCONN is not set, EPROTO is treated as a temporary error.
