Hi,
I have added a flow rule as follows:
ovs-ofctl add-flow OFSWITCH priority=501,dl_type=0x800,nw_dst=
10.0.0.0/24,actions=output:3,mod_dl_dst:de:ad:ba:be:ba:be
I see that packets entering my bridge with dest_IP 10.0.0.1 hit this flow
rule and go out on the specified port. I however, dont see the the
destination MAC address being updated as expected.

OF port 3 is a GRE tunnel end-point. I expect to see the dest MAC of the
inner payload to get replaced with the MAC that i specify in the flow-rule.
Is there something that i am missing?
Thanks, Abhishek
