[LTP] [RFC PATCH v4 0/3] Simplify network setup

Hi Alexey,

I fixed all errors but "line over 80 characters".
How does checkpatch.pl [1] counts line length As I get many "line over 80
characters", but my Vim shows that line is less than 80 chars.

Silly question, but how did you compile to get this error? I don't get them
$ i=testcases/lib/tst_net_vars; rm -fv $i; ma -C `dirname $i`

Thanks!
