WizNet W6100/W5500 MACRAW mode does not add MAC headers?

Hello, I am using W6100 in MACRAW mode with LWIP stack (on my host controller).

When I send a packet over SOCKET0, it seems like w6100 is sending it out without adding source and destination MAC addresses to my payload.

My test setup:
1. Host controller operates w6100 over SPI in MACRAW mode
2. W6100 is connected to my PC over Ethernet cable
3. I am using Wireshark to monitor traffic over Ethernet interface

So, my payload is: 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f . . . 40

However, at my PCs end Wireshark is showing SRC address as 06 07 08 09 0a 0b. So, it seems like MAC of W6100 did not append Ethernet MAC headers to my payload.

Doesn't MACRAW mode entail that MAC headers are appended by the wiznet chip? Has any body run into the same issue? Or am I missing anything?
