From 31bd204f97e3796c5cfcfc582a93a10e45b99946 Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Tue, 26 Apr 2011 18:58:59 +0200 Subject: [PATCH] r8169: provide some firmware information via ethtool. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There is no real firmware version yet but the manpage of ethtool is rather terse about the driver information. Former output: $ ethtool -i eth1 driver: r8169 version: 2.3LK-NAPI firmware-version: bus-info: 0000:01:00.0 $ ethtool -i eth0 driver: r8169 version: 2.3LK-NAPI firmware-version: bus-info: 0000:03:00.0 Current output: $ ethtool -i eth1 driver: r8169 version: 2.3LK-NAPI firmware-version: N/A bus-info: 0000:01:00.0 $ ethtool -i eth0 driver: r8169 version: 2.3LK-NAPI firmware-version: rtl_nic/rtl8168d-1.fw bus-info: 0000:03:00.0 Signed-off-by: Francois Romieu Fixed-by Ciprian Docan Cc: Realtek linux nic maintainers Cc: Fejes József Cc: Borislav Petkov --- drivers/net/r8169.c | 45 +++++++++++++++++++++++++-------------------- 1 file changed, 25 insertions(+), 20 deletions(-) diff --git a/drivers/net/r8169.c b/drivers/net/r8169.c index 81906bc919a4..83e5202d30aa 100644 --- a/drivers/net/r8169.c +++ b/drivers/net/r8169.c @@ -1188,6 +1188,19 @@ static int rtl8169_set_wol(struct net_device *dev, struct ethtool_wolinfo *wol) return 0; } +static const char *rtl_lookup_firmware_name(struct rtl8169_private *tp) +{ + int i; + + for (i = 0; i < ARRAY_SIZE(rtl_firmware_infos); i++) { + const struct rtl_firmware_info *info = rtl_firmware_infos + i; + + if (info->mac_version == tp->mac_version) + return info->fw_name; + } + return NULL; +} + static void rtl8169_get_drvinfo(struct net_device *dev, struct ethtool_drvinfo *info) { @@ -1196,6 +1209,8 @@ static void rtl8169_get_drvinfo(struct net_device *dev, strcpy(info->driver, MODULENAME); strcpy(info->version, RTL8169_VERSION); strcpy(info->bus_info, pci_name(tp->pci_dev)); + strncpy(info->fw_version, IS_ERR_OR_NULL(tp->fw) ?
