removed old ifconfig code and replaced with ip from iputils
removed old ifconfig code and replaced with ip from iputils
since ifconfig is a deprecated utility and is replaced by iputils, by switching to iputils it brings more consistency to the code (part of it was already using it) and it will ease maintenance due to the fact that ifconfig will become more and more unknown
removed unused local variable "i" in the "unpack_apkvol" function
