Jumbo frames: Yes

Jumbo frames: Yes: "So how large should an Ethernet frame be? Ethernet's 32-bit cyclic redundancy check is effective for detecting bit errors at frame sizes under 12,000 bytes, thereby drawing a logical upper limit. Within that, the optimum large frame size can be determined by an application's block size. For example, Network File System (NFS) transfers data in 8,192-byte blocks. So adding room for headers, an attractive maximum Ethernet frame size for NFS applications is 9,000 bytes."
