Most of the time spent on reading sources & docs. 7 * v0.2.x First official release for the Linux kernel. 8 * v0.3.0 Beutified and structured, some bugs fixed. 9 * v0.3.x URBifying bulk requests and bugfixing. First relatively 10 * stable release. Still can touch device's registers only 11 * from top-halves. 12 * v0.4.0 Control messages remained unurbified are now URBs. 13 * Now we can touch the HW at any time. 14 * v0.4.9 Control urbs again use process context to wait. Argh... 15 * Some long standing bugs (enable_net_traffic) fixed. 16 * Also nasty trick about resubmiting control urb from 17 * interrupt context used. Please let me know how it 18 * behaves. Pegasus II support added since this version. 19 * TODO: suppressing HCD warnings spewage on disconnect. 20 * v0.4.13 Ethernet address is now set at probe(), not at open() 21 * time as this seems to break dhcpd. 22 * v0.5.0 branch to 2.5.x kernels 23 * v0.5.1 ethtool support added 24 * v0.5.5 rx socket buffers are in a pool and the their allocation 25 * is out of the interrupt routine. 26 * ... 27 * v0.9.3 simplified [get|set]_register(s), async update registers 28 * logic revisited, receive skb_pool removed. 29 */ 30 31 #include <linux/sched.h> 32 #include <linux/slab.h> 33 #include <linux/init.h> 34 #include <linux/delay.h> 35 #include <linux/netdevice.h> 36 #include <linux/etherdevice.h> 37 #include <linux/ethtool.h> 38 #include <linux/mii.h> 39 #include <linux/usb.h> 40 #include <linux/module.h> 41 #include <asm/byteorder.h> 42 #include <linux/uaccess.h> 43 #include "pegasus.h" 44 45 /* 46 * Version Information 47 */ 48 #define DRIVER_VERSION "v0.9.3 (2013/04/25)" 49 #define DRIVER_AUTHOR "Petko Manolov <petkan@nucleusys.com>" 50 #define DRIVER_DESC "Pegasus/Pegasus II USB Ethernet driver" 51 52 static const char driver_name[] = "pegasus"; 53 54 #undef PEGASUS_WRITE_EEPROM 55 #define BMSR_MEDIA (BMSR_10HALF | BMSR_10FULL | BMSR_100HALF | \ 56 BMSR_100FULL | BMSR_ANEGCAPABLE) 57 #define CARRIER_CHECK_DELAY (2 * HZ) 58 59 static bool loopback; 60 static bool mii_mode; 61 static char *devid; 62 63 static struct usb_eth_dev usb_dev_id[] = { 64 #define PEGASUS_DEV(pn, vid, pid, flags) \ 65 {.name = pn, .vendor = vid, .device = pid, .private = flags}, 66 #define PEGASUS_DEV_CLASS(pn, vid, pid, dclass, flags) \ 67 PEGASUS_DEV(pn, vid, pid, flags) 68 #include "pegasus.h" 69 #undef PEGASUS_DEV 70 #undef PEGASUS_DEV_CLASS 71 {NULL, 0, 0, 0}, 72 {NULL, 0, 0, 0} 73 }; 74 75 static struct usb_device_id pegasus_ids[] = { 76 #define PEGASUS_DEV(pn, vid, pid, flags) \ 77 {.match_flags = USB_DEVICE_ID_MATCH_DEVICE, .idVendor = vid, .idProduct = pid}, 78 /* 79 * The Belkin F8T012xx1 bluetooth adaptor has the same vendor and product 80 * IDs as the Belkin F5D5050, so we need to teach the pegasus driver to 81 * ignore adaptors belonging to the "Wireless" class 0xE0.
