Description
I'm using AWS and trying to test machnet for different AWS regions
When I try to run the hello world example, on the sender side I always got
ERROR: Failed to dequeue response from control queue.
machnet_connect() failed
Then I tried to create another VM in the same region, and the hello world works. This suggested something is wrong when it's cross regions?
I then also tried to build DPDK and run dpdk-testpmd on both end, and it shows it's receiving. The caveat is that for --eth-peer I need to specify the gateway MAC instead of the NIC MAC. I don't see similar setting in machnet, can you advise if this is indeed the issue and any potential fixes? Thanks in advance!

Research direction
Start with the hello world example and the AWS cross-region setup described in the issue. Compare the failing machnet connection with the working same-region run and the dpdk-testpmd behavior, especially the gateway MAC used with --eth-peer. Done means cross-region behavior is explained and either supported with a fix or documented as a limitation.
