Regarding third party firmware support, Realtek SoC support in OpenWrt
+ (success) RTL8196C port status. on the OpenWrt Forum
and the Realtek thread on the DD-WRT Forum may be of interest.

This device appears to be targeted for use with 3JTech's IP cameras.

"RoHS", "DWR rev 0.2", and "UL and 94V-0" is silkscreened on the board in the FCC photos.

Per a MAC label affixed to the FCC EUT, a 00:09:B5 OUI is presumed to be used by this device.

... however, the bottom label shows it with a 00:E0:4C (Realtek) OUI... Both (or just the RTL one) may be used.
