trafgen: proto: Add ICMPv4 header generation
Support for generating ICMPv4 headers using the 'icmp4()/icmpv4()'
trafgen generation functions.
Fields supported:
type Set type field (default 0: Echo reply)
Supported keywords: echorequest, echoreply
code Set code field (default 0)
csum Set checksum field (calculated by default)
mtu Set mtu field for destination unreachable (default 0)
seq Set sequence field (default 0)
id Set identifier field (default 0)
addr Set redirect address (default 0.0.0.0)
Example (send ping request):
{ icmpv4(echorequest, seq=1, id=1326) }
