Howto configure the Linux kernel / net / packet Packet configuration * Option: PACKET * Kernel Versions: 2.6.15.6 ... * (on/off/module) Packet socket The Packet protocol is used by applications which communicate directly with network devices without an intermediate network protocol implemented in the kernel, e.g. tcpdump. If you want them to work, choose Y. To compile this driver as a module, choose M here: the module will be called af_packet. If unsure, say Y. * Option: PACKET_MMAP * Kernel Versions: 2.6.15.6 ... * (on/off) Packet socket: mmapped IO * depends on PACKET If you say Y here, the Packet protocol driver will use an IO mechanism that results in faster communication. If unsure, say N.
