From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michael Chan Subject: [PATCH net-next v2 7/9] bnxt_en: Simplify and improve unsupported SFP+ module reporting. Date: Sun, 15 May 2016 03:04:49 -0400 Message-ID: <1463295891-15216-8-git-send-email-michael.chan@broadcom.com> References: <1463295891-15216-1-git-send-email-michael.chan@broadcom.com> Cc: netdev@vger.kernel.org To: davem@davemloft.net Return-path: Received: from mail-pa0-f47.google.com ([209.85.220.47]:35103 "EHLO mail-pa0-f47.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754085AbcEOHFJ (ORCPT ); Sun, 15 May 2016 03:05:09 -0400 Received: by mail-pa0-f47.google.com with SMTP id iv1so54189904pac.2 for ; Sun, 15 May 2016 00:05:08 -0700 (PDT) In-Reply-To: <1463295891-15216-1-git-send-email-michael.chan@broadcom.com> Sender: netdev-owner@vger.kernel.org List-ID: The current code is more complicated than necessary and can only report unsupported SFP+ module if it is plugged in after the device is up. Rename bnxt_port_module_event() to bnxt_get_port_module_status(). We already have the current module_status in the link_info structure, so just check that and report any unsupported SFP+ module status. Delete the unnecessary last_port_module_event. Call this function at the end of bnxt_open to report unsupported module already plugged in.
