Gigabit LAN
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
A sample of the GbLAN chips in different PS3 models:
| Ports | Size | Speed | Voltage | Packaging | Manufacturer | Serial Number | Description |
|---|---|---|---|---|---|---|---|
| 8 (3 used) | 20x20mm | Xtal X3501: 25MHz | 3.3V/1.9V/1.2V | 144-pin TQFP | Marvell | 88E6108-LAR1 | Used in earlier models (up to CECHGxx/SEM-00x) |
| ? | ? | ? | ? | ? | Marvell | 88E6106-LKJ1 | Used in later models (CECHHxx/DIA-00x) |
| - | - | 125MHz | 3.3V, 2.5V or 1.8V | 64-pin QFN | Marvell | Alaska 88E1118R-NNC2 | Used in Slim models (CECH-20xx/DYN-00x) |
Jumbo frames
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.
