jun's mode ds918+ loader,
with 0.5 test extra.lzma
tn40xx won't regconize tehuiti tn9710p 10GBase/t NIC QM2-2P10G1T ,let along those ssd on nvme 2280 port.
DSM6.1X/DSM6.2 both tested.
but nvme list can see those ssd on the list.
dmesg cannot grep 10gb nic ,but kernel kmesg says tn40xx detected,still not load module though.
tehuti tn9710p 10GBase/t NIC QM2-2P10G1T provided both linux/os x driver currently works fine in my hackintosh.
so , image something must be patchable with synology driver,i assume tn40xx has some opensource we can dig out.
