Gigabit LAN[edit | edit source]
The PS3 has 1 Gigabit Ethernet port. The port accepts Auto-MDIX (automatic medium-dependent interface crossover), so no need for special crosscables when hooking up the PS3 direct to the PC.
Gigabit LAN chips used[edit | edit source]
A sample of the GbLAN chips in different PS3 models:
Ports | Size | Speed | Voltage | Packaging | Manufacturer | Serial Number | Description |

Jumbo frames[edit | edit source]
From Linux perspective (under OtherOS <=3.15), the old drivers set the MTU to 2308, while newer versions set the MTU of 1518. This could be a hypervisor restriction (needs research).
MTU is set with vsh using syscall net_ioctl (libnet)
On 3.41 firmware, with a modified ps3_gelic driver, frames of 1624 bytes can be sent and frames of 1628 bytes can be received.
Efficiency[edit | edit source]
