trafgen: parser: Add syntax to generate Ethernet header fields
Add function 'eth()' to support generating Ethernet header fields from the trafgen configuration language. Supported fields: da|daddr destination address, default: 00:00:00:00:00:00 sa|saddr source address, default: device MAC prot|proto protocol number, default: 0x0000 Example usage: { eth(prot=0x0800, da=11:22:33:44:55:66), fill(0xff, 60) } { eth(prot=0x0800) } { eth() } It is important that proto_init is called before fields will be filled to initialize the specified proto with header fields.
