From: Magnus Karlsson <magnus.karlsson@intel.com>

Add a command line option to be able to run a single test. This option
(-t) takes a number from the list of tests available with the "-l"
option. Here are two examples:

Run test number 2, the "receive single packet" test in all available modes:

./test_xsk.sh -t 2

Run test number 21, the metadata copy test in zero-copy mode only

./test_xsh.sh -t 21 -m zc

for above you have to provide -i $IFACE as well

how are you protecting against something like:

sudo ./test_xsk.sh -t asdasd -m zc -i enp24s0f1np1
