From 46c1376db1b85ae412a7917cec148c6e60f79428 Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Fri, 20 Jun 2014 14:26:25 -0500 Subject: [PATCH] RDMA/cxgb4: Call iwpm_init() only once We need to only register with the iwpm core once. Currently it is being done for every adapter, which causes a failure for each adapter but the first, making multiple adapters unusable.
