Proto-typing SRv6 functions with P4 lang.

p4srv6's Issues

/demo/srv6/end.am cannot be operated correctly

~$ ./p4/behavioral-model/tools/runtime_CLI.py
action end_am(PortId_t oif, EthernetAddress dmac)
oif=3, dmac=, priority=100(required for ternary table)
action end_am_d(PortId_t oif)
oif=2

What does the piece of code mean? I have strictly followed the instructions except this unknown code and I cannot operate the demo of /demo/srv6/end.am correctly. Could you explain this code in detail?
(ps. I can operate the demo of l2fwd corrrectly with the instructions and my enviroments is ok)
Looking forward to your reply~

Support PSP (Penultimate Segment Pop)

1. list all SRv6 functions which could have PSP
2. consider helper action to consolidate processing PSP operation common to SRv6 functions.

Refactor End for different SL

There are two options (so far).

1. use ipv6_srh.segmentsLeft as part of match key and call srv6_End0, srv6_End1 ... according to SL.
2. Flag srv6-action matched in metadata and have srh-post-process table to do all process which would change depending on ipv6_srh.segmentsLeft.

2. could be a generic table handling different SRv6 functions (P4 actions).

Add udp checksum

Update UDP checksum in gtp_encap and srv6_End_M_GTP6_E.

Port VLAN support

Add port VLAN support to prepare for mac flooding which is required for mac learning.
