As you may have noticed, the 4x25G are downgraded to 4x10G since the delta can not do 25G =P

Hey Csaba,

I have a question and I guess it may be interesting for other users. I have managed to bring up some 10g ports with a breakout 100 to 4X25 in the wedge towards the Delta.

I want to configure a 802.3ad bundle for 4 ports in the P4 dataplane.

I guess I need to add the bundle as in https://github.com/mc36/freeRouter/blob/6e1607d8db29eceacc1f69db3ef12d9eebfbd6c6/cfg/conn-bundle04.tst

The ports are already up and configured in 4 interfaces (details below), so I guess I just have to add bun interface plus bundle-gr the 4 sdn28x interfaces, right?

Jordi
