| 2016-08-05 | trafgen: proto: Use field id as array index | Vadim Kochan | 1 | -2/+2 | |
| Usually proto fields array are sorted in the same order as the respective enum. Thus, the id can be used used as an array index for faster lookup. Add an explanatory comment and enforce the correspondence of id and index using bug_on(). This will make csum field calculation a little faster at runtime.

| 2016-04-25 | trafgen: proto: Add IPv6 header generation | Tobias Klauser | 1 | -0/+11 | |
| 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.

| 2016-01-29 | trafgen: l3: Add IPv4 header generation backend | Vadim Kochan | 1 | -0/+25 | |
| Add L3 module for implement L3 layer protocols generation. Implemented setting of IPv4 header with all fields except options. By default IPv4 address of output device is used as src ip address. On finish (after packet is specified) - total len & checksum are calculated. Meanwhile Ethernet protocol is initialized as default lower header. If the lower protocol is IPv4 then IPv4 protocol id is set to IP-in-IP in lower protocol header.
