I just hit the same problem recently and also looked into that script.
I'm not sure if this bashism or just sloppy programming, the fix for this
particular one is simple - just put double quotes around the expression:
local LINK="$($ETHTOOL "$IFACE" 2>&1 | grep "Link detected" || :)"
But, looking onto the code in general it looks to me that it needs some
love, for example in the declaration section:
ABORT_NO_LINK=i${ABORT_NO_LINK:-no}
Make whole variable useless and not working(note leading 'i', 'vi' is
evil:>)
I hope to get some time and clean up the script.
