Hi,

Dataplane capability detection has been added.
https://bitbucket.software.geant.org/projects/RARE/repos/rare/commits/cf51c189f50754010190ceab543713a40d8c11a2

The list has been fetch using p4src: grep -r HAVE_ ./p4src | awk ‘{ print
$NF}’ | sort | uniq
Everything is checked except HAVE_NOHW and HAVE_SCRAMBLE

As the code is the source of truth here, if new features ([in|e]gress
control, table, action etc. ), one will have to advertise the ew capability.
Of course if this has been built with the correct profile with bf-p4c.

The following message is sent back from bf_forwarder to the control plane:

DAV0001#debug server p4lang rx
DAV0001#term mon
DAV0001#debug servP4langConn.doRound:servP4lang.java:1485 rx: capability mpls
nat acl_in acl_out
warning servP4lang.srvAccept:servP4lang.java:618 neighbor 127.0.0.1 up


I presume this can be extensively tested with mc36 profile factory and Alex’s
package !

Can’t wait to see the result.

Now let’s cross fingers so it passes mc36 automated QC’s :-)

All the best
fl
