trafgen: proto: Add IPv6 header generation
Support for generating simple IPv6 headers using the 'ip6()/ipv6()'
trafgen generation function.
Fields supported:
ver|version Version (default: 6)
tc|tclass Traffic class (default: 0)
fl|flow Flow Label (default: 0)
len|length Payload length (calculated by default)
nh|nexthdr Type of next header (default: 0)
hl|hoplimit|ttl Hop Limit, TTL (default: 0)
sa|saddr Source IPv6 address (default: device address)
da|daddr Destination IPv6 address (default: 0:0:0:0:0:0:0:0)
Examples:
{ eth(), ipv6(daddr=1:2:3:4:5:6:7:8) }
{ ipv6(tc=2, hl=3, daddr=::1) }
{ eth(), ipv6(nh=58, sa=2001:db8::, da=::1), 128, 0, 0x52, 0x03, 0, 0, 0, 0 }
If not explicitely specified, the lower header is initialized as Ethernet.
