If the ip fragmentation backport is enabled, we should always use our
own {,__}ipv6_select_ident(). This fixes the following issue on some
v3.19 kernels:
datapath/linux/ip6_output.c:93:12: error: conflicting types for
‘__ipv6_select_ident’
static u32 __ipv6_select_ident(struct net *net, u32 hashrnd,
