dcb.8: some remarks and editorial changes for this manual

[Bjarni Ingi Gislason <bjarniig@simnet.is>]

  The man page is from Debian:

Package: iproute2
Version: 6.11.0-1
Severity: minor
Tags: patch

  Improve the layout of the man page according to the "man-page(7)"
guidelines, the output of "mandoc -lint T", the output of
"groff -mandoc -t -ww -b -z", that of a shell script, and typographical
conventions.

 .SH ARRAY PARAMETERS
 
 Like commands, specification of parameters is in the domain of individual
-objects (and their commands) as well. However, much of the DCB interface
-revolves around arrays of fixed size that specify one value per some key, such
-as per traffic class or per priority. There is therefore a single syntax for
-adjusting elements of these arrays. It consists of a series of
-\fIKEY\fB:\fIVALUE\fR pairs, where the meaning of the individual keys and values
-depends on the parameter.

+It consists of a series of \fIKEY\fB:\fIVALUE\fR pairs,
+where the meaning of the individual keys and values depends on the parameter.
 
 The elements are evaluated in order from left to right, and the latter ones
-override the earlier ones. The elements that are not specified on the command
+override the earlier ones.
+The elements that are not specified on the command
 line are queried from the kernel and their current value is retained.
 
 As an example, take a made-up parameter tc-juju, which can be set to charm
-traffic in a given TC with either good luck or bad luck. \fIKEY\fR can therefore
-be 0..7 (as is usual for TC numbers in DCB), and \fIVALUE\fR either of
-\fBnone\fR, \fBgood\fR, and \fBbad\fR. An example of changing a juju value of
-TCs 0 and 7, while leaving all other intact, would then be:
+traffic in a given TC with either good luck or bad luck.

 .P
 # dcb foo set dev eth0 tc-juju 0:good 7:bad
 
 A special key, \fBall\fR, is recognized which sets the same value to all array
-elements. This can be combined with the usual single-element syntax. E.g. in the
-following, the juju of all keys is set to \fBnone\fR, except 0 and 7, which have
+elements.
