RG directory - using the Rogers variant of the CFE. TM directory - using the T-Mobile variant of the CFE. in the RG directory... various edited changes to the CFE (usually MAC addresses) that derived from the Rogers variant OEM CFE. In other words, they are technically incorrect. They do work, however. in the TM directory... the wrong MAC address variants have the Rogers MAC address unedited alongside the original MAC address. How this happened is likely a setting oversight, as even the only known TM variant CFE dump has the Rogers wl0 MAC address present. Not necessarily a factory oversight, but someone partially using a Rogers variant CFE in the process to create the Linux CFE converter. You will have to fix the wl0/il0 MAC address with a hex editor after conversion. the semi-wrong MAC address variants have the Rogers MAC address edited to be the Wireless MAC so it will show up properly in certain third-party firmware, as some others use a +2 calculation for the wl0 as a workaround. However, this was a first attempt, and the MAC address order follows the WRT54G v8 - eth0 MAC is two spots before the Wireless MAC, e.g. eth0 is 00:1a:70:fe:5a:7d, wl0 is 00:1a:70:fd:5a:7f. There is a problem: WRT54G v8 has a separate WAN MAC address which is not present on a WRT54GS v3.0 (it is between the eth0 and wl0 PHY), so it is technically wrong. the proper MAC address variants finally fixes the MAC address order of eth0 and wl0 after looking at the RG OEM variant CFE. The CFE's eth0 MAC address is actually after the wl0 MAC address. The eth0 address is also on the bottom of your router. example: eth0 is 00:1a:70:fe:5a:7d and wl0 is 00:1a:70:fd:5a:7d.
