#139 iperf-2.1.4.tar.gz: configure syntax error

[Lee]

iperf-2.1.4.tar.gz downloaded from SF has a problem in configure:
...
checking whether TPACKET_V2 is declared... no
./configure: line 4430: ,: command not found
checking whether IFF_TUN is declared... no

which looks like a typo in configure:
$as_echo "#define HAVE_AF_PACKET 1" >>confdefs.h

else
enable_af_packet="no"
fi
,
if test "x${enable_af_packet}" = "xyes"; then

delete the comma on line 4430 and no complaints from configure
