[dpdk-dev] Build failure on Ubuntu 14.04

[Wiles, Roger Keith]

Hi All,

I got a build failure on :

[10:20][keithw at keithw-W2600CR:umf(dev)]$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04 LTS
Release:        14.04
Codename:       trusty

Looks like the skb_set_hash() function changed from:

static inline void
skb_set_hash(struct sk_buff *skb, __u32 hash, __always_unused int type)
{
    skb->rxhash = hash;
}

To:

static inline void
skb_set_hash(struct sk_buff *skb, __u32 hash, enum pkt_hash_types type)
{
    skb->l4_rxhash = (type == PKT_HASH_TYPE_L4);
    skb->rxhash = hash;
}

Compile line: 'make install T=x86_64-native-linuxapp-gcc'
...
