[LTP] [PATCH 0/3] networking/stress: add ip xfrm ipsec support

[Hangbin Liu]

Hi Alexey and Cyril,

Sorry for the late patches. I was bussy with other stuff durning previous
months. Here I only add an ipsec lib and add ip xfrm support for
icmp4-uni-basic01. I will fix other tests when you feel these patches are
OK.

As we know, most of the network stress tests have IPsec testing, and we use
setkey for configuration. But setkey[1] hasn't updated for a long time. And
some distros, RHEL7 for example, even don't have ipset-tools package. On
other hand, iproute2 is recommend for network configuration. And ip xfrm is
more powerful than setkey. So let's use ip xfrm for ipsec testing.

For c2x function in ipsec_lib.sh. It's only a convert function and do not
print any info. So I kept it with the old style.

Here is the test result:
