Yes, I can confirm that the trusty-proposed 3.13.0-38 kernel resolves this issue. The dnsmasq-tftp transfer succeeds in my test environment without any of the symptoms that were present with the trusty- updates/security kernels between -30 and -37, nor do I notice any regressions in my (IPv4) ipvs ruleset.
