What this means
The IEEE assigned the MA-L block EC4644 to TTK SAS. Every network interface they manufacture under this block has a MAC address beginning with these digits, followed by a unique per-device identifier. If a device on your network shows a MAC starting EC:46:44, it is TTK SAS hardware.
