Networking and servers • Re: What are the offloading capabilities of the Pi 5 ethernet interface?

As a percentage what sort of improvement can you get with this feature and under what circumstances? Generally, ethernet performance on the Pi 5 is very good, reaching close to the theoretical maximum.
Couldn't find any published benchmarks for rx-vlan-offload and tx-vlan-offload. My own tests showed a 20% throughput increase, but on a device with a less powerful CPU than the Raspberry Pi. I expect diminishing returns as the CPU gets faster.

My understanding is that the Pi 4 used the Broadcom BCM54213PE Ethernet PHY. What PHY does the Pi 5 now use?
