ESXi 6.7 U2 breaks jumbo frames within VLAN trunk portgroups

I came across this post by /u/thakala on Reddit, which covers a scenario where ESXi 6.7 U2 is apparently causing dropped packets for Network Function Virtualisation (NFV) workloads.

No specific support ticket has been raised with VMware according to the various commenters on the above thread, but it is worth keeping in mind if you are looking at installing ESXi 6.7 U2 in your environment.

EDIT: ESXi 6.7 U2a has now been announced, but this issue is not mentioned in the release notes.
