SPDX-License-Identifier: GPL-2.0 - -=================== -SB100 device driver -=================== - -sb1000 is a module network device driver for the General Instrument (also known -as NextLevel) SURFboard1000 internal cable modem board. This is an ISA card -which is used by a number of cable TV companies to provide cable modem access. -It's a one-way downstream-only cable modem, meaning that your upstream net link -is provided by your regular phone modem. - -This driver was written by Franco Venturi <fventuri@mediaone.net>. He deserves -a great deal of thanks for this wonderful piece of code! - -Needed tools -============ - -Support for this device is now a part of the standard Linux kernel. The -driver source code file is drivers/net/sb1000.c. In addition to this -you will need: - -1. The "cmconfig" program. This is a utility which supplements "ifconfig" - to configure the cable modem and network interface (usually called "cm0"); - -2. Several PPP scripts which live in /etc/ppp to make connecting via your - cable modem easy. - - These utilities can be obtained from: - - http://www.jacksonville.net/~fventuri/ - - in Franco's original source code distribution .tar.gz file. Support for - the sb1000 driver can be found at: - - - http://web.archive.org/web/%2E/http://home.adelphia.net/~siglercm/sb1000.html - - http://web.archive.org/web/%2E/http://linuxpower.cx/~cable/ - - along with these utilities. - -3. The standard isapnp tools. These are necessary to configure your SB1000 - card at boot time (or afterwards by hand) since it's a PnP card. - - If you don't have these installed as a standard part of your Linux - distribution, you can find them at: - - http://www.roestock.demon.co.uk/isapnptools/ - - or check your Linux distribution binary CD or their web site. For help with - isapnp, pnpdump, or /etc/isapnp.conf, go to: - - http://www.roestock.demon.co.uk/isapnptools/isapnpfaq.html - -Using the driver -================ - -To make the SB1000 card work, follow these steps: - -1. Run ``make config``, or ``make menuconfig``, or ``make xconfig``, whichever - you prefer, in the top kernel tree directory to set up your kernel - configuration. Make sure to say "Y" to "Prompt for development drivers" - and to say "M" to the sb1000 driver. Also say "Y" or "M" to all the standard - networking questions to get TCP/IP and PPP networking support. - -2. **BEFORE** you build the kernel, edit drivers/net/sb1000.c. Make sure - to redefine the value of READ_DATA_PORT to match the I/O address used - by isapnp to access your PnP cards. This is the value of READPORT in - /etc/isapnp.conf or given by the output of pnpdump. - -3. Build and install the kernel and modules as usual. - -4. Boot your new kernel following the usual procedures. - -5. Set up to configure the new SB1000 PnP card by capturing the output - of "pnpdump" to a file and editing this file to set the correct I/O ports, - IRQ, and DMA settings for all your PnP cards. Make sure none of the settings - conflict with one another. Then test this configuration by running the - "isapnp" command with your new config file as the input. Check for - errors and fix as necessary. (As an aside, I use I/O ports 0x110 and - 0x310 and IRQ 11 for my SB1000 card and these work well for me. YMMV.) - Then save the finished config file as /etc/isapnp.conf for proper - configuration on subsequent reboots. - -6. Download the original file sb1000-1.1.2.tar.gz from Franco's site or one of - the others referenced above. As root, unpack it into a temporary directory - and do a ``make cmconfig`` and then ``install -c cmconfig /usr/local/sbin``. - Don't do ``make install`` because it expects to find all the utilities built - and ready for installation, not just cmconfig. - -7. As root, copy all the files under the ppp/ subdirectory in Franco's - tar file into /etc/ppp, being careful not to overwrite any files that are - already in there. Then modify ppp@gi-on to set the correct login name, - phone number, and frequency for the cable modem. Also edit pap-secrets - to specify your login name and password and any site-specific information - you need. - -8. Be sure to modify /etc/ppp/firewall to use ipchains instead of - the older ipfwadm commands from the 2.0.x kernels. There's a neat utility to - convert ipfwadm commands to ipchains commands: - - http://users.dhp.com/~whisper/ipfwadm2ipchains/ - - You may also wish to modify the firewall script to implement a different - firewalling scheme. - -9. Start the PPP connection via the script /etc/ppp/ppp@gi-on. You must be - root to do this. It's better to use a utility like sudo to execute - frequently used commands like this with root permissions if possible. If you - connect successfully the cable modem interface will come up and you'll see a - driver message like this at the console:: - - cm0: sb1000 at (0x110,0x310), csn 1, S/N 0x2a0d16d8, IRQ 11. - sb1000.c:v1.1.2 6/01/98 (fventuri@mediaone.net) - - The "ifconfig" command should show two new interfaces, ppp0 and cm0. - - The command "cmconfig cm0" will give you information about the cable modem - interface. - -10. Try pinging a site via ``ping -c 5 www.yahoo.com``, for example. You should - see packets received. - -11. If you can't get site names (like www.yahoo.com) to resolve into - IP addresses (like 204.71.200.67), be sure your /etc/resolv.conf file - has no syntax errors and has the right nameserver IP addresses in it. - If this doesn't help, try something like ``ping -c 5 204.71.200.67`` to - see if the networking is running but the DNS resolution is where the - problem lies. - -12. If you still have problems, go to the support web sites mentioned above - and read the information and documentation there. - -Common problems -=============== - -1. Packets go out on the ppp0 interface but don't come back on the cm0 - interface. It looks like I'm connected but I can't even ping any - numerical IP addresses. (This happens predominantly on Debian systems due - to a default boot-time configuration script.) - -Solution - As root ``echo 0 > /proc/sys/net/ipv4/conf/cm0/rp_filter`` so it - can share the same IP address as the ppp0 interface. Note that this - command should probably be added to the /etc/ppp/cablemodem script - *right*between* the "/sbin/ifconfig" and "/sbin/cmconfig" commands. - You may need to do this to /proc/sys/net/ipv4/conf/ppp0/rp_filter as well. - If you do this to /proc/sys/net/ipv4/conf/default/rp_filter on each reboot - (in rc.local or some such) then any interfaces can share the same IP - addresses. - -2. I get "unresolved symbol" error messages on executing ``insmod sb1000.o``. - -Solution - You probably have a non-matching kernel source tree and - /usr/include/linux and /usr/include/asm header files. Make sure you - install the correct versions of the header files in these two directories. - Then rebuild and reinstall the kernel. - -3. When isapnp runs it reports an error, and my SB1000 card isn't working. - -Solution - There's a problem with later versions of isapnp using the "(CHECK)" - option in the lines that allocate the two I/O addresses for the SB1000 card. - This first popped up on RH 6.0. Delete "(CHECK)" for the SB1000 I/O addresses. - Make sure they don't conflict with any other pieces of hardware first! Then - rerun isapnp and go from there. - -4. I can't execute the /etc/ppp/ppp@gi-on file. - -Solution - As root do ``chmod ug+x /etc/ppp/ppp@gi-on``. - -5. The firewall script isn't working (with 2.2.x and higher kernels). - -Solution - Use the ipfwadm2ipchains script referenced above to convert the - /etc/ppp/firewall script from the deprecated ipfwadm commands to ipchains. - -6. I'm getting *tons* of firewall deny messages in the /var/kern.log, - /var/messages, and/or /var/syslog files, and they're filling up my /var - partition!!! - -Solution - First, tell your ISP that you're receiving DoS (Denial of Service) - and/or portscanning (UDP connection attempts) attacks! Look over the deny - messages to figure out what the attack is and where it's coming from. Next, - edit /etc/ppp/cablemodem and make sure the ",nobroadcast" option is turned on - to the "cmconfig" command (uncomment that line). If you're not receiving these - denied packets on your broadcast interface (IP address xxx.yyy.zzz.255 - typically), then someone is attacking your machine in particular. Be careful - out there.... - -7. Everything seems to work fine but my computer locks up after a while - (and typically during a lengthy download through the cable modem)! - -Solution - You may need to add a short delay in the driver to 'slow down' the - SURFboard because your PC might not be able to keep up with the transfer rate - of the SB1000. To do this, it's probably best to download Franco's - sb1000-1.1.2.tar.gz archive and build and install sb1000.o manually. You'll - want to edit the 'Makefile' and look for the 'SB1000_DELAY' - define. Uncomment those 'CFLAGS' lines (and comment out the default ones) - and try setting the delay to something like 60 microseconds with: - '-DSB1000_DELAY=60'. Then do ``make`` and as root ``make install`` and try - it out. If it still doesn't work or you like playing with the driver, you may - try other numbers. Remember though that the higher the delay, the slower the - driver (which slows down the rest of the PC too when it is actively - used). Thanks to Ed Daiga for this tip! - -Credits -======= - -This README came from Franco Venturi's original README file which is -still supplied with his driver .tar.gz archive. I and all other sb1000 users -owe Franco a tremendous "Thank you!" Additional thanks goes to Carl Patten -and Ralph Bonnell who are now managing the Linux SB1000 web site, and to -the SB1000 users who reported and helped debug the common problems listed -above. - - - Clemmitt Sigler - csigler@vt.edu diff --git a/Documentation/networking/device_drivers/index.rst b/Documentation/networking/device_drivers/index.rst index 0dd30a84ce25..a254af25b7ef 100644 --- a/Documentation/networking/device_drivers/index.rst +++ b/Documentation/networking/device_drivers/index.rst @@ -9,7 +9,6 @@ Contents: :maxdepth: 2 atm/index - cable/index can/index cellular/index ethernet/index diff --git a/arch/powerpc/configs/ppc6xx_defconfig b/arch/powerpc/configs/ppc6xx_defconfig index ca0c90e95837..e69260b5d67f 100644 --- a/arch/powerpc/configs/ppc6xx_defconfig +++ b/arch/powerpc/configs/ppc6xx_defconfig @@ -485,7 +485,6 @@ CONFIG_VIA_VELOCITY=m CONFIG_PCMCIA_XIRC2PS=m CONFIG_FDDI=y CONFIG_SKFP=m -CONFIG_NET_SB1000=m CONFIG_BROADCOM_PHY=m CONFIG_CICADA_PHY=m CONFIG_DAVICOM_PHY=m diff --git a/drivers/acpi/acpi_pnp.c b/drivers/acpi/acpi_pnp.c index 01abf26764b0..435ec60a9682 100644 --- a/drivers/acpi/acpi_pnp.c +++ b/drivers/acpi/acpi_pnp.c @@ -120,8 +120,6 @@ static const struct acpi_device_id acpi_pnp_device_ids[] = { {"IBM0071"}, /* smsc-ircc2 */ {"SMCf010"}, - /* sb1000 */ - {"GIC1000"}, /* parport_pc */ {"PNP0400"}, /* Standard LPT Printer Port */ {"PNP0401"}, /* ECP Printer Port */ diff --git a/drivers/net/Kconfig b/drivers/net/Kconfig index 1fd5acdc73c6..271520510b5f 100644 --- a/drivers/net/Kconfig +++ b/drivers/net/Kconfig @@ -518,30 +518,6 @@ source "drivers/net/hippi/Kconfig" source "drivers/net/ipa/Kconfig" -config NET_SB1000 - tristate "General Instruments Surfboard 1000" - depends on ISA && PNP - help - This is a driver for the General Instrument (also known as - NextLevel) SURFboard 1000 internal - cable modem.
