Asynchronous Transfer Mode (ATM)" tristate default n help ATM is a high-speed networking technology for Local Area Networks and Wide Area Networks. It uses a fixed packet size and is connection oriented, allowing for the negotiation of minimum bandwidth requirements. In order to participate in an ATM network, your Linux box needs an ATM networking card. If you have that, say Y here and to the driver of your ATM card below. Note that you need a set of user-space programs to actually make use of ATM. See the file for further details. config ADK_KPACKAGE_KMOD_ATM_BR2684 prompt "kmod-atm-br2684................... BR2684 ATM module" tristate select ADK_KPACKAGE_KMOD_ATM default n help config ADK_KPACKAGE_KMOD_BRIDGE prompt "kmod-bridge....................... 802.1d Ethernet Bridging" tristate select ADK_KERNEL_LLC default n help If you say Y here, then your Linux box will be able to act as an Ethernet bridge, which means that the different Ethernet segments it is connected to will appear as one Ethernet to the participants. Several such bridges can work together to create even larger networks of Ethernets using the IEEE 802.1 spanning tree algorithm. As this is a standard, Linux bridges will cooperate properly with other third party bridge products. In order to use the Ethernet bridge, you'll need the bridge configuration tools; see for location. Please read the Bridge mini-HOWTO for more information. If you enable iptables support along with the bridge support then you turn your bridge into a bridging IP firewall. iptables will then see the IP packets being bridged, so you need to take this into account when setting up your firewall rules. Enabling arptables support when bridging will let arptables see bridged ARP traffic in the arptables FORWARD chain. config ADK_KPACKAGE_KMOD_VLAN_8021Q prompt "kmod-vlan......................... 802.1q VLAN support" tristate default n help Select this and you will be able to create 802.1Q VLAN interfaces on your ethernet interfaces. 802.1Q VLAN supports almost everything a regular ethernet interface does, including firewalling, bridging, and of course IP traffic. You will need the 'vconfig' tool from the VLAN project in order to effectively use VLANs. See the VLAN web page for more information: config ADK_KPACKAGE_KMOD_INET_TUNNEL tristate default n help config ADK_KPACKAGE_KMOD_NET_IPIP prompt "kmod-net-ipip..................... IP in IP encapsulation support" tristate select ADK_KPACKAGE_KMOD_INET_TUNNEL default n help Tunneling means encapsulating data of one protocol type within another protocol and sending it over a channel that understands the encapsulating protocol. This particular tunneling driver implements encapsulation of IP within IP, which sounds kind of pointless, but can be useful if you want to make your (or some other) machine appear on a different network than it physically is, or to use mobile-IP facilities (allowing laptops to seamlessly move between networks without changing their IP addresses). config ADK_KPACKAGE_KMOD_NET_IPGRE prompt "kmod-net-ipgre.................... GRE tunnels over IP" tristate #depends on ADK_KPACKAGE_KMOD_NET_IPGRE_BROADCAST default n help Tunneling means encapsulating data of one protocol type within another protocol and sending it over a channel that understands the encapsulating protocol. This particular tunneling driver implements GRE (Generic Routing Encapsulation) and at this time allows encapsulating of IPv4 or IPv6 over existing IPv4 infrastructure. This driver is useful if the other endpoint is a Cisco router: Cisco likes GRE much better than the other Linux tunneling driver ("IP tunneling" above). In addition, GRE allows multicast redistribution through the tunnel. config ADK_KPACKAGE_KMOD_IPV6 prompt "kmod-ipv6......................... IPv6 support" tristate default n help This is complemental support for the IP version 6. You will still be able to do traditional IPv4 networking as well. For general information about IPv6, see . For Linux IPv6 development information, see . For specific information about IPv6 under Linux, read the HOWTO at . config ADK_KPACKAGE_KMOD_IPV6_SIT prompt "kmod-ipv6-sit..................... IPv6-in-IPv4 tunnel (SIT driver)" tristate select ADK_KPACKAGE_KMOD_INET_TUNNEL default n help Tunneling means encapsulating data of one protocol type within another protocol and sending it over a channel that understands the encapsulating protocol. This driver implements encapsulation of IPv6 into IPv4 packets. This is useful if you want to connect two IPv6 networks over an IPv4-only path. config ADK_KPACKAGE_KMOD_PPP prompt "kmod-ppp.......................... PPP support" tristate select ADK_KERNEL_NETDEVICES select ADK_KERNEL_PPP_ASYNC select ADK_KERNEL_SLHC select ADK_KPACKAGE_KMOD_CRC_CCITT default n help PPP (Point to Point Protocol) is a newer and better SLIP. It serves the same purpose: sending Internet traffic over telephone (and other serial) lines. Ask your access provider if they support it, because otherwise you can't use it; most Internet access providers these days support PPP rather than SLIP. To use PPP, you need an additional program called pppd as described in the PPP-HOWTO, available at . Make sure that you have the version of pppd recommended in . The PPP option enlarges your kernel by about 16 KB. There are actually two versions of PPP: the traditional PPP for asynchronous lines, such as regular analog phone lines, and synchronous PPP which can be used over digital ISDN lines for example. If you want to use PPP over phone lines or other asynchronous serial lines, you need to say Y (or M) here and also to the next option, "PPP support for async serial ports". For PPP over synchronous lines, you should say Y (or M) here and to "Support synchronous PPP", below. config ADK_KPACKAGE_KMOD_PPP_MPPE prompt "kmod-ppp-mppe...................

This is called 'Etherchannel' by Cisco, 'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux. The driver supports multiple bonding modes to allow for both high performance and high availability operation.
