Hi everyone,
I'm just wondering how could I using awk language merge two files by comparison of one their row.
I mean, I have one file like this:
file#1:

CM(4) BSD Kernel Interfaces Manual CM(4)NAME
cm -- SMC Arcnet Ethernet device driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device isa
device cm
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_cm_load="YES"
DESCRIPTION
The cm driver provides support for the Arcnet ISA network adapters.
This driver also has quirks preset in the device.hints(5) file for card detection.
HARDWARE
The cm driver supports the following card models:
o SMC90c26
o SMC90c56
o SMC90c66 in '56 compatibility mode.
IMPLEMENTATION NOTES
When the NOARP flag is set on the cm interface, it does not employ the address resolution protocol described in arp(4) to dynamically map
between Internet and Ethernet addresses on the local network. Instead it uses the least significant 8 bits of the IP address as the hardware
address like described in RFC 1051 and RFC 1201.
With the IFF_LINK0 flag cleared IP/ARP/RARP encoding is done according to RFC 1201 that is, with Packet Header Definition Standard header and
packet type 212 / 213. The MTU is normally 1500. The IFF_LINK0 flag is cleared by default.
With the IFF_LINK0 flag set, IP and ARP encoding is done according to the deprecated RFC 1051 encoding, that is with simple header, packet
type 240 / 241, and the MTU is 507.
When switching between the two modes, use
ifconfig interfacename down up
to switch the MTU.
DIAGNOSTICS
The following driver specific error messages may be reported:
reset: card reset, link addr = 0x%02x (cm%d) The card is being reset and a new link address assigned.
srint: restarted rx on buf cm%d The rx buffer has been emptied and will be reset.

The cm device was ported from NetBSD by Max Khon <fjoe@FreeBSD.org> and first appeared in FreeBSD 4.6. This manual page first appeared in
FreeBSD 5.3.
AUTHORS
This manual page was written by Tom Rhodes <trhodes@FreeBSD.org>. The IMPLEMENTATION NOTES section was submitted by
Max Khon <fjoe@FreeBSD.org> and originated from NetBSD.
BUGS
The cm driver code could do with a bit of improvement, it would be nice if some one could come along and take care of this.
The IMPLEMENTATION NOTES section is specific to all Arcnet devices (see sys/net/if_arcsubr.c) and should be moved to a more generic location.
