From d1fbe04eee32ed2642cff139b8592866f1d43f41 Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Tue, 24 Mar 2009 20:44:18 -0700 Subject: RDMA/cxgb3: Enforce required firmware The cxgb3 NIC driver can handle more firmware versions than iw_cxgb3, and since commit 8207befa ("cxgb3: untie strict FW matching") cxgb3 will load with firmware versions that iw_cxgb3 can't handle. The FW major number indicates a specific interface between the FW and iw_cxgb3. Thus if the major number of the running firmware does not match the required version compiled into iw_cxgb3, then iw_cxgb3 must not register that device.
