From a4f81a61ebba5953cba1e76f66423a7eca4a5ee4 Mon Sep 17 00:00:00 2001 From: "A.YOSHIYAMA" Date: Tue, 15 Nov 2005 09:55:18 +0200 Subject: [PATCH] USB: usb-net: new device ID passed through module parameter adds new module parameter "devid" that points to a string with format "device_name:vendor_id:device_id:flags". if provided at module load time, this string is being parsed and a new entry is created in usb_dev_id[] and pegasus_ids[] so the new device can later be recognized by the probe routine. this might be helpful for someone who don't know/wish to build new module/kernel, but want to use his new usb-to-eth device that is not yet listed in pegasus.h Signed-off-by: Petko Manolov Signed-off-by: Greg Kroah-Hartman --- drivers/usb/net/pegasus.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) (limited to 'drivers/usb/net') diff --git a/drivers/usb/net/pegasus.c b/drivers/usb/net/pegasus.c index d8c7adabf20..156a2f1cb39 100644 --- a/drivers/usb/net/pegasus.c +++ b/drivers/usb/net/pegasus.c @@ -57,12 +57,14 @@ static const char driver_name[] = "pegasus"; static int loopback = 0; static int mii_mode = 0; +static char *devid=NULL; static struct usb_eth_dev usb_dev_id[] = { #define PEGASUS_DEV(pn, vid, pid, flags) \ {.name = pn, .vendor = vid, .device = pid, .private = flags}, #include "pegasus.h" #undef PEGASUS_DEV + {NULL, 0, 0, 0}, {NULL, 0, 0, 0} }; @@ -71,6 +73,7 @@ static struct usb_device_id pegasus_ids[] = { {.match_flags = USB_DEVICE_ID_MATCH_DEVICE, .idVendor = vid, .idProduct = pid}, #include "pegasus.h" #undef PEGASUS_DEV + {}, {} }; @@ -79,8 +82,10 @@ MODULE_DESCRIPTION(DRIVER_DESC); MODULE_LICENSE("GPL"); module_param(loopback, bool, 0); module_param(mii_mode, bool, 0); +module_param(devid, charp, 0); MODULE_PARM_DESC(loopback, "Enable MAC loopback mode (bit 0)"); MODULE_PARM_DESC(mii_mode, "Enable HomePNA mode (bit 0),default=MII mode = 0"); +MODULE_PARM_DESC(devid, "The format is: 'DEV_name:VendorID:DeviceID:Flags'"); /* use ethtool to change the level for any given device */ static int msg_level = -1; @@ -1410,9 +1415,42 @@ static struct usb_driver pegasus_driver = { .resume = pegasus_resume, }; +static void parse_id(char *id) +{ + unsigned int vendor_id=0, device_id=0, flags=0, i=0; + char *token, *name=NULL; + + if ((token = strsep(&id, ":")) != NULL) + name = token; + /* name now points to a null terminated string*/ + if ((token = strsep(&id, ":")) != NULL) + vendor_id = simple_strtoul(token, NULL, 16); + if ((token = strsep(&id, ":")) != NULL) + device_id = simple_strtoul(token, NULL, 16); + flags = simple_strtoul(id, NULL, 16); + pr_info("%s: new device %s, vendor ID 0x%04x, device ID 0x%04x, flags: 0x%x\n", + driver_name, name, vendor_id, device_id, flags); + + if (vendor_id > 0x10000 || vendor_id == 0) + return; + if (device_id > 0x10000 || device_id == 0) + return; + + for (i=0; usb_dev_id[i].name; i++); + usb_dev_id[i].name = name; + usb_dev_id[i].vendor = vendor_id; + usb_dev_id[i].device = device_id; + usb_dev_id[i].private = flags; + pegasus_ids[i].match_flags = USB_DEVICE_ID_MATCH_DEVICE; + pegasus_ids[i].idVendor = vendor_id; + pegasus_ids[i].idProduct = device_id; +} + static int __init pegasus_init(void) { pr_info("%s: %s, " DRIVER_DESC "\n", driver_name, DRIVER_VERSION); + if (devid) + parse_id(devid); pegasus_workqueue = create_singlethread_workqueue("pegasus"); if (!pegasus_workqueue) return -ENOMEM; -- cgit v1.2.3
