+#       bondslaves is a comma-separated list of physical (ethernet) interfaces

+#       if options include multi-valued arp_ip_target option, then its values should be separated by semicolon.

+#       if the mtu is specified, it will be set on the bond master

+# We translate list of slaves to space-separated here to make it easier to loop over them in ifup
