From: Jacob Keller <[email protected]> Based on hardware testing, the host interface supports up to 15368 bytes as the maximum frame size. To determine the correct MTU, we subtract 8 for the internal switch tag, 14 for the L2 header, and 4 for the appended FCS header, resulting in 15342 bytes of payload for our maximum MTU on jumbo frames.
