If I try to create a hash:mac set, like this:
ipset create MACSFREE hash:mac
The console never returns, only if I hit CTRL+C, it works for other
types of sets, here is the strace:
strace ipset create MACSFREE hash:mac
execve("/usr/local/sbin/ipset", ["ipset", "create", "MACSFREE",
"hash:mac"], [/* 30 vars */]) = 0
