thanks in advance... :)
yeahh, normally it was really that the bundle table missed the default entry
to pass the packet straight...
after implementing the workaround, i saw the it in the bfshell and it started
passing packets in the model...

Good to hear that we finally have a workaround that doesn't have any
drawbacks (disabling dead-code elimination breaks some of our profiles
due to lack of sufficient PHVs). I'll give it a try on my Tofino2 as
soon as I find the time (hopefully today or tomorrow).

hi,
vlad finally dissected the root cause of the tofino2 not forwarding packets
issue and provided us a workaround:
https://community.intel.com/t5/Intel-Connectivity-Research/Port-P4-program-from-TOFINO-1-to-TOFINO-2/m-p/1449228#M4888
i've just implemented it
(https://github.com/rare-freertr/freeRtr/commit/9ec9e9ddad436aa7571ab5ecc592c272dff1b2bd)
and found that it works great in the model but i dont have access to a real
box...
so im writing to you if you can give this a quick try to see on a real
hardware?
if everything is fine then i'll commit this to the bitbucket too at least
during the weekend bump...
(if it's easier for you, the
https://bitbucket.software.geant.org/projects/RARE/repos/rare/browse/update-src.sh
will fetch it for you...)
thanks,
cs
