Subject [2/2] git commit: updated refs/heads/4.6 to 4f6ff6c
Date Fri, 04 Dec 2015 09:45:37 GMT
Merge pull request #1163 from remibergsma/arping-to-gw

Send arping to the gateway instead of our own addressWe need to send an Unsolicited ARP to
the gateway, instead of our own address. We now encounter problems when people deploy/destroy/deploy
and get the same public ip.

Packets arrive, but with incorrect / cached mac and are ignored by the routervm kernel.
Run arping manually to update the arp-cache on the gateway and things start to work.

Then we discovered the `arping` is actually done, but sent to its own address. Therefore the
gateway doesn't pick it up. We only saw this happening when rapid deploy tools are used, like
Terraform that do deploy/destroy/deploy and might get the same ip but on a new router having
a new mac.

The integration tests seem happy, although the full run is still ongoing:

=== TestName: test_01_create_redundant_VPC_2tiers_4VMs_4IPs_4PF_ACL | Status : SUCCESS ===

Thanks @sspans for helping trouble shoot this. Ping @wilderrodrigues can you review please?
