Subject: [PATCH] TT#28952 Replace 'ifdata' with 'sed' utility

There is problem with package 'moreutils' which contains 'ifdata'
so replace it with parsing of 'ip-address' output with 'sed'

Change-Id: Ic4af3e32b5cd36aa8efd706d21805acff7a50459
(cherry picked from commit 5302549bc2af2b254d5712f0a6eb0450d30567f0)
