Pull networking updates from David Miller: 1) BPF debugger and asm tool by Daniel Borkmann. 2) Speed up create/bind in AF_PACKET, also from Daniel Borkmann. 3) Correct reciprocal_divide and update users, from Hannes Frederic Sowa and Daniel Borkmann. 4) Currently we only have a "set" operation for the hw timestamp socket ioctl, add a "get" operation to match. From Ben Hutchings. 5) Add better trace events for debugging driver datapath problems, also from Ben Hutchings. 6) Implement auto corking in TCP, from Eric Dumazet. Basically, if we have a small send and a previous packet is already in the qdisc or device queue, defer until TX completion or we get more data. 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko. 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel Borkmann. 9) Share IP header compression code between Bluetooth and IEEE802154 layers, from Jukka Rissanen. 10) Fix ipv6 router reachability probing, from Jiri Benc. 11) Allow packets to be captured on macvtap devices, from Vlad Yasevich. 12) Support tunneling in GRO layer, from Jerry Chu. 13) Allow bonding to be configured fully using netlink, from Scott Feldman. 14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can already get the TCI. From Atzm Watanabe. 15) New "Heavy Hitter" qdisc, from Terry Lam. 16) Significantly improve the IPSEC support in pktgen, from Fan Du. 17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom Herbert. 18) Add Proportional Integral Enhanced packet scheduler, from Vijay Subramanian. 19) Allow openvswitch to mmap'd netlink, from Thomas Graf. 20) Key TCP metrics blobs also by source address, not just destination address. From Christoph Paasch. 21) Support 10G in generic phylib. From Andy Fleming. 22) Try to short-circuit GRO flow compares using device provided RX hash, if provided. From Tom Herbert. The wireless and netfilter folks have been busy little bees too. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (2064 commits) net/cxgb4: Fix referencing freed adapter ipv6: reallocate addrconf router for ipv6 address when lo device up fib_frontend: fix possible NULL pointer dereference rtnetlink: remove IFLA_BOND_SLAVE definition rtnetlink: remove check for fill_slave_info in rtnl_have_link_slave_info qlcnic: update version to 5.3.55 qlcnic: Enhance logic to calculate msix vectors. qlcnic: Refactor interrupt coalescing code for all adapters. qlcnic: Update poll controller code path qlcnic: Interrupt code cleanup qlcnic: Enhance Tx timeout debugging. qlcnic: Use bool for rx_mac_learn. bonding: fix u64 division rtnetlink: add missing IFLA_BOND_AD_INFO_UNSPEC sfc: Use the correct maximum TX DMA ring size for SFC9100 Add Shradha Shah as the sfc driver maintainer. net/vxlan: Share RX skb de-marking and checksum checks with ovs tulip: cleanup by using ARRAY_SIZE() ip_tunnel: clear IPCB in ip_tunnel_xmit() in case dst_link_failure() is called net/cxgb4: Don't retrieve stats during recovery ... |

Copy the firmware image (e.g. usb8388.bin) to /lib/firmware/ o. Load driver by using the following command: insmod usb8388.ko [fw_name=usb8388.bin] ========================= ETHTOOL ========================= Use the -i option to retrieve version information from the driver. # ethtool -i eth0 driver: libertas version: COMM-USB8388-318.p4 firmware-version: 5.110.7 bus-info: Use the -e option to read the EEPROM contents of the card. Usage: ethtool -e ethX [raw on|off] [offset N] [length N] -e retrieves and prints an EEPROM dump for the specified ethernet device. When raw is enabled, then it dumps the raw EEPROM data to stdout. The length and offset parameters allow dumping cer- tain portions of the EEPROM. Default is to dump the entire EEP- ROM. # ethtool -e eth0 offset 0 length 16 Offset Values ------ ------ 0x0000 38 33 30 58 00 00 34 f4 00 00 10 00 00 c4 17 00 ======================== DEBUGFS COMMANDS ======================== those commands are used via debugfs interface =========== rdmac rdbbp rdrf These commands are used to read the MAC, BBP and RF registers from the card. These commands take one parameter that specifies the offset location that is to be read. This parameter must be specified in hexadecimal (its possible to precede preceding the number with a "0x"). Path: /sys/kernel/debug/libertas_wireless/ethX/registers/ Usage: echo "0xa123" > rdmac ; cat rdmac echo "0xa123" > rdbbp ; cat rdbbp echo "0xa123" > rdrf ; cat rdrf wrmac wrbbp wrrf These commands are used to write the MAC, BBP and RF registers in the card. These commands take two parameters that specify the offset location and the value that is to be written. This parameters must be specified in hexadecimal (its possible to precede the number with a "0x"). Usage: echo "0xa123 0xaa" > wrmac echo "0xa123 0xaa" > wrbbp echo "0xa123 0xaa" > wrrf sleepparams This command is used to set the sleepclock configurations Path: /sys/kernel/debug/libertas_wireless/ethX/ Usage: cat sleepparams: reads the current sleepclock configuration echo "p1 p2 p3 p4 p5 p6" > sleepparams: writes the sleepclock configuration. where: p1 is Sleep clock error in ppm (0-65535) p2 is Wakeup offset in usec (0-65535) p3 is Clock stabilization time in usec (0-65535) p4 is Control periodic calibration (0-2) p5 is Control the use of external sleep clock (0-2) p6 is reserved for debug (0-65535) subscribed_events The subscribed_events directory contains the interface for the subscribed events API. Path: /sys/kernel/debug/libertas_wireless/ethX/subscribed_events/ Each event is represented by a filename. Each filename consists of the following three fields: Value Frequency Subscribed To read the current values for a given event, do: cat event To set the current values, do: echo "60 2 1" > event Frequency field specifies the reporting frequency for this event. If it is set to 0, then the event is reported only once, and then automatically unsubscribed. If it is set to 1, then the event is reported every time it occurs. If it is set to N, then the event is reported every Nth time it occurs. beacon_missed Value field specifies the number of consecutive missing beacons which triggers the LINK_LOSS event. This event is generated only once after which the firmware resets its state. At initialization, the LINK_LOSS event is subscribed by default. The default value of MissedBeacons is 60. failure_count Value field specifies the consecutive failure count threshold which triggers the generation of the MAX_FAIL event. Once this event is generated, the consecutive failure count is reset to 0. At initialization, the MAX_FAIL event is NOT subscribed by default. high_rssi This event is generated when the average received RSSI in beacons goes above a threshold, specified by Value. low_rssi This event is generated when the average received RSSI in beacons goes below a threshold, specified by Value. high_snr This event is generated when the average received SNR in beacons goes above a threshold, specified by Value. low_snr This event is generated when the average received SNR in beacons goes below a threshold, specified by Value. extscan This command is used to do a specific scan. Path: /sys/kernel/debug/libertas_wireless/ethX/ Usage: echo "SSID" > extscan Example: echo "LINKSYS-AP" > extscan To see the results of use getscantable command. getscantable Display the current contents of the driver scan table (ie. get the scan results). Path: /sys/kernel/debug/libertas_wireless/ethX/ Usage: cat getscantable setuserscan Initiate a customized scan and retrieve the results Path: /sys/kernel/debug/libertas_wireless/ethX/ Usage: echo "[ARGS]" > setuserscan where [ARGS]: bssid=xx:xx:xx:xx:xx:xx specify a BSSID filter for the scan ssid="[SSID]" specify a SSID filter for the scan keep=[0 or 1] keep the previous scan results (1), discard (0) dur=[scan time] time to scan for each channel in milliseconds type=[1,2,3] BSS type: 1 (Infra), 2(Adhoc), 3(Any) Any combination of the above arguments can be supplied on the command line. If dur tokens are absent, the driver default setting will be used. The bssid and ssid fields, if blank, will produce an unfiltered scan. The type field will default to 3 (Any) and the keep field will default to 0 (Discard). Examples: 1) Perform a passive scan on all channels for 20 ms per channel: echo "dur=20" > setuserscan 2) Perform an active scan for a specific SSID: echo "ssid="TestAP"" > setuserscan 3) Scan all available channels (B/G, A bands) for a specific BSSID, keep the current scan table intact, update existing or append new scan data: echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan 4) Scan for all infrastructure networks. Keep the previous scan table intact. Update any duplicate BSSID/SSID matches with the new scan data: echo "type=1 keep=1" > setuserscan All entries in the scan table (not just the new scan data when keep=1) will be displayed upon completion by use of the getscantable ioctl. hostsleep This command is used to enable/disable host sleep. Note: Host sleep parameters should be configured using "ethtool -s ethX wol X" command before enabling host sleep. Path: /sys/kernel/debug/libertas_wireless/ethX/ Usage: cat hostsleep: reads the current hostsleep state echo "1" > hostsleep : enable host sleep. echo "0" > hostsleep : disable host sleep
