The board is UEFI, not standard bios. And while it will merrily boot OpenWRT's non-uefi images off of USB, it won't boot the non-UEFI setup from the internal storage (I'm using the eMMC). So _that_ was fun (and I made some dumb mistakes that were especially fun to correct.</div><div><br></div><div>But it's running OpenWRT 19.07 (and a UEFI bootloader before grub that's from ToT OpenWRT).</div><div><br></div><div>Anyway, I have cake running, 950Mbps ingress and 35Mbps egress (modem is provisioned at 1.3G ingress, and a bit over 35Mbps egress). fq_codel was defaulted, in multi-queue mode.
