[oe] [meta-oe][PATCH v2] rarpd : add new recipe

RARP (Reverse Address Resolution Protocol) is a protocol which allows
individual devices on an IP network to get their own IP addresses from
the RARP server. Some machines (e.g. SPARC boxes) use this protocol
instead of e.g. DHCP to query their IP addresses during network bootup.
Linux kernels up to 2.2 used to provide a kernel daemon for this
service,but since 2.3 kernels it is served by this userland daemon.
You should install rarpd if you want to set up a RARP server on your
network.

++.TH RARP 8 "7 April 2000" "rarpd" "Linux Programmer's Manual"
++.SH NAME
++rarpd \- Reverse Address Resolution Protocol (RARP) daemon
++.SH SYNOPSIS
++.B "rarpd [-aAvde] [-b bootdir ] [ interface ]"
++.SH DESCRIPTION
++.B Rarpd
++is a daemon which responds to RARP requests.
++RARP is used by some machines at boot time to discover their IP address.
++They provide their Ethernet address and
++.B rarpd
++responds with their IP address if it finds it in the ethers database
++(either
++.I /etc/ethers
++file or NIS+ lookup) and using DNS lookup if ethers database
++contains a hostname and not an IP address.
++By default
++.B rarpd
++also checks if a bootable image with a name starting with the IP address
++in hexadecimal uppercase letters is present in the TFTP boot directory
++(usually
++.I /tftpboot
++) before it decides to respond to the RARP request.
++.SH OPTIONS
++.TP
++.B \-a
++Do not bind to the interface.
++.TP
++.B \-A
++Respond to ARP as well as RARP requests.
++.TP
++.B \-v
++Tell the user what is going on by being verbose.
++.TP
++.B \-d
++Debugging mode. Do not detach from the tty.
++.TP
++.B \-e
++Skip the check for bootable image in the TFTP boot directory. If not
++present, then even if the Ethernet address is present in
++the ethers database but the bootable image for the resolved IP does not exist,
++.B rarpd
++will not respond to the request.
++.TP
++.B "\-b bootdir"
++Use
++.I bootdir
++instead of the default
++.I /tftpboot
++as the TFTP boot directory for bootable image checks.
++.SH OBSOLETES
++This
++.B rarpd
++obsoletes kernel
++.B rarp
++daemon present in Linux kernels up to 2.2 which was controlled by the
++rarp(8) command.
++.SH FILES
++.I /etc/ethers,
++.br
++.I /etc/nsswitch.conf,
++.br
++.I /tftpboot
++.SH SEE ALSO
++ethers(5)

+SUMMARY = "The RARP daemon."
+DESCRIPTION = "RARP (Reverse Address Resolution Protocol) is a protocol which \
+allows individual devices on an IP network to get their own IP addresses from \
+the RARP server. Some machines (e.g. SPARC boxes) use this protocol instead \
+of e.g. DHCP to query their IP addresses during network bootup. \
+Linux kernels up to 2.2 used to provide a kernel daemon for this service, \
+but since 2.3 kernels it is served by this userland daemon. \
+You should install rarpd if you want to set up a RARP server on your \
+network."
