[dpdk-dev] how to build 'example' folder in dpdk-2.2.0?

[Sam]

hi all,

I want to build example(DPDK_HOME/example/*) in dpdk, and to have a look at
vhost demo. But I can't find guide in dpdk home page or document.

So is there some document to tell me HOWTO?

Currently, we have:

#define PKT_TX_TUNNEL_VXLAN   (0x1ULL << 45)
in binary:     000..000[0001]000..000

#define PKT_TX_TUNNEL_GRE     (0x2ULL << 45)
in binary:     000..000[0010]000..000

#define PKT_TX_TUNNEL_IPIP    (0x3ULL << 45)
in binary:     000..000[0011]000..000

#define PKT_TX_TUNNEL_GENEVE  (0x4ULL << 45)
in binary:     000..000[0100]000..000

So, I'm still saying there's a room for 11 more values.
