|  | tristate "Packet socket" | 
|  | ---help--- | 
|  | 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. | 
|  |  | 
|  | config PACKET_MMAP | 
|  | bool "Packet socket: mmapped IO" | 
|  | depends on PACKET | 
|  | help | 
|  | If you say Y here, the Packet protocol driver will use an IO | 
|  | mechanism that results in faster communication. | 
|  |  | 
|  | If unsure, say N. |
