From c0bf8801535d45df3597839edf864e24f60a4188 Mon Sep 17 00:00:00 2001 From: Brice Goglin Date: Fri, 9 May 2008 02:18:24 +0200 Subject: myri10ge: report FIBER in ethtool for XFP based NIC Make ethtool report FIBER for XFP based NIC's port type. Don't bother to poke around and try to find out what is in the XFP cage, since Linux does not have separate media types for -SR -LR, etc. Signed-off-by: Brice Goglin Signed-off-by: Andrew Gallatin Signed-off-by: Jeff Garzik --- drivers/net/myri10ge/myri10ge.c | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) (limited to 'drivers/net/myri10ge') diff --git a/drivers/net/myri10ge/myri10ge.c b/drivers/net/myri10ge/myri10ge.c index 3f871c467ed2..4a65e4155c0f 100644 --- a/drivers/net/myri10ge/myri10ge.c +++ b/drivers/net/myri10ge/myri10ge.c @@ -205,6 +205,7 @@ struct myri10ge_priv { int pause; char *fw_name; char eeprom_strings[MYRI10GE_EEPROM_STRINGS_SIZE]; + char *product_code_string; char fw_version[128]; int fw_ver_major; int fw_ver_minor; @@ -421,6 +422,10 @@ static int myri10ge_read_mac_addr(struct myri10ge_priv *mgp) ptr += 1; } } + if (memcmp(ptr, "PC=", 3) == 0) { + ptr += 3; + mgp->product_code_string = ptr; + } if (memcmp((const void *)ptr, "SN=", 3) == 0) { ptr += 3; mgp->serial_number = simple_strtoul(ptr, &ptr, 10); @@ -1304,9 +1309,39 @@ static irqreturn_t myri10ge_intr(int irq, void *arg) static int myri10ge_get_settings(struct net_device *netdev, struct ethtool_cmd *cmd) { + struct myri10ge_priv *mgp = netdev_priv(netdev); + char *ptr; + int i; + cmd->autoneg = AUTONEG_DISABLE; cmd->speed = SPEED_10000; cmd->duplex = DUPLEX_FULL; + + /* + * parse the product code to deterimine the interface type + * (CX4, XFP, Quad Ribbon Fiber) by looking at the character + * after the 3rd dash in the driver's cached copy of the + * EEPROM's product code string. + */ + ptr = mgp->product_code_string; + if (ptr == NULL) { + printk(KERN_ERR "myri10ge: %s: Missing product code\n", + netdev->name); + return 0; + } + for (i = 0; i < 3; i++, ptr++) { + ptr = strchr(ptr, '-'); + if (ptr == NULL) { + printk(KERN_ERR "myri10ge: %s: Invalid product " + "code %s\n", netdev->name, + mgp->product_code_string); + return 0; + } + } + if (*ptr == 'R' || *ptr == 'Q') { + /* We've found either an XFP or quad ribbon fiber */ + cmd->port = PORT_FIBRE; + } return 0; } -- cgit v1.2.3
