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:
| Type | Size | Speed | Voltage | Packaging | Manufacturer | Serial Number | Description |
|---|---|---|---|---|---|---|---|
| - | - | - | - | - | Marvell | 88E6108-LAR1 | Used in earlier models |
| - | - | - | - | - | Marvell | Alaska 88E111R | Used in Slim models |
Marvell 88E6108-LAR1 (IC3503)
Datasheet: (not available)
productcode meaning: 88E6108-LAR1 Type: Ethernet Speed : 1Gbps Ports : 8 Package : 144-TQFP (sorry, no explaination yet)
The Marvell 88E6108-LAR1 is sort of a switching hub chip, with several ports that can be used in different configurations:
Port 0 (usuable as MDI 4 dif.pair) : unused (tied to ground) Port 1 (usuable as MDI 4 dif.pair) : unused (tied to ground) Port 2 (usuable as MDI 4 dif.pair) : wired to external UTP connector Port 3 (GMII): Wired to SB Port 4 (usable as TX/RX dif.pair)(100FX): wired to Wifi Port 5 (usable as TX/RX dif.pair): unused (tied to ground) Port 6 (usable as TX/RX dif.pair): unused (tied to ground) Port 7 (usable as TX/RX dif.pair): unused (tied to ground)

From Linux perspective (under OtherOS <=3.15), the old drivers set up MTU to 2308, while newer version used MTU 1518. This could be a hypervisor restriction (needs research).
