hoshino is a powerful router with which I plan to eventually replace helian. helian is an excellent device, but I want more speed and more ports.
hoshino is connected to sabrina via a 2x10G LAG, mostly for redundancy as nothing will be pushing that much bandwidth.
hoshino is a Mikrotik CCR2004-16G-2S+:

Features and uses
- 16x 1G RJ45 ports
- 2x 10G SFP+ ports
Hardware
Marvell 88E6191X switch chip for each block of 8 frontpanel ports, which determines which features can be L3-hardware-offloaded. This is an interesting situation because there's two switch chips, meaning you can't put ports from different blocks into the same bridge - one bridge per switch chip. This is fine, you're running a router so you don't expect to do a lot of bridging.
It's not clear whether any routing is hardware-offloaded. Probably not, I think it sticks to L2 purely: https://help.mikrotik.com/docs/spaces/ROS/pages/62390319/L3+Hardware+Offloading#L3HardwareOffloading-L3HWDeviceSupport
The 10G SFP ports are connected directly to the CPU, so there's nothing to offload to.
Config
It'll need to mostly do what helian does now, which a bit of VLAN wrangling on the side.
The rest of this is TBC.
