Ethernet Controllers

SIc: /* Intel Gigabit (10/100/1000) */

== Internal Ethernet controller ==

A variety of [[Ethernet]] controllers is integrated into almost all models starting with the introduction of the A, T and X series.

The Ethernet controller is located on either a MiniPCI card, Communications Daughter Card (CDC), or integrated on the systemboard.

=== 3COM Fast Ethernet (10/100) ===
MiniPCI cards featuring this chip:
*[[3Com 10/100 Ethernet Mini-PCI Adapter with 56K Modem]]

=== Intel Fast Ethernet (10/100) ===
CDC and MiniPCI cards featuring this chip:
*[[Ethernet Daughter Card (EDC)]]
*[[Intel 10/100 Ethernet Mini-PCI Adapter with 56K Modem]]
*[[Intel PRO/100 SP Mobile Combo Adapter]]
*[[Mini-PCI Ethernet card]]
*[[Xircom 10/100 EtherJet Mini PCI Adapter with 56K Modem]]

In addition, this chip is integrated into select systemboards of the following machines: 
'''Intel 82550GY'''
* {{R30}}
'''Intel 82558'''
* [[SelectaBase PC Card Enabler with Advanced EtherJet]]
* [[ThinkPad Port Replicator with Advanced EtherJet]]
'''Intel 82562ET'''
* {{R31}}, {{R32}}
* {{T30}}
* {{X30}}
'''Intel 82562EZ'''
* {{R40}}, {{R50e}}, {{R50}}, {{R51}}
* {{T40}}
* {{X31}}

Driver: [[e100]] (The 'e100' driver is the suggested driver, but '[[eepro100]]' should also work.)

=== Intel Gigabit (10/100/1000) ===
Chipset: Intel PRO/1000 MT Mobile Ethernet 
Driver: [[e1000]]

This chip is integrated into select systemboards of the following machines: 
'''Intel 82540EP'''
* {{R50}}, {{R50p}}, {{R51}}
* {{T40}}, {{T40p}}, {{T41}}, {{T41p}}, {{T42}}, {{T42p}}
* {{X31}}, {{X32}}
'''Intel 82541GI'''
* {{R51}}
* {{X40}}
'''Intel 82573L''' (PCI-Express)
* {{T60}}, {{T60p}}
* {{X60}}, {{X60s}}
** Note: known to freeze the whole system on Ubuntu 8.10 when used with the e1000 driver, while e1000e driver does not recognize the adapter - see https://bugs.launchpad.net/ubuntu/+bug/226906/
'''Intel 82566MM''' (PCI-Express) (w/ [[Intel Active Management Technology (AMT)]])
* {{T61}}, {{T61p}}, {{X61}}, {{X61s}}, {{X61_Tablet}}
'''Intel 82567LM''' (PCI-Express) (w/ [[Intel Active Management Technology (AMT)]])
* {{X200}}
* Driver: [[e1000e]]
Note: DO NOT(!!!) use the "irqpoll" boot parameter. This causes the network card to lose it's irq, and makes any stability of the network connection impossible.
Note: There is a [[Problem with e1000: Open issue with latency|known issue]] with the e1000, t60/t60p and the 2.6.17 kernel. It is unconfirmed if this issue effects other configurations. 
Note: This chip supports Auto-MDIX, meaning you will never need a crossover ethernet cable. 
Note: The first signs of explicit support for this chip in 2.6 kernels is with 2.6.12-rc2. 
Note: Red Hat Enterprise Linux 3.0 (2.4 kernel based) begins 82573L support with Update 7. 
Note: Some users report issues: [[Problem_with_e1000:_EEPROM_Checksum_Is_Not_Valid]]. This issue stands behind the symptom, that the intel controller 82573L will only work, if a network cable is attached at boot time (seen at X60 running with ubuntu). 
Note: Some users have reported [http://forum.thinkpads.com/viewtopic.php?p=201279&sid=787564d7cf9de5d7d76b0cb312a98c61 latency problems] with e1000 driver. It seems, that [http://agenda.clustermonkey.net/index.php/Tuning_Intel_e1000_NICs switching off Interupt Throttle Rate (ITR)] helps. 
Note: [http://support.intel.com/support/network/sb/CS-009209.htm Additional configuration options from Intel] 
Note: Another possibility is to use "RxIntDelay=5". 
Note: How to repair a destroyed eeprom because of the e1000 Kernel bug (Kernel 2.6.27) -> [http://tournament.de/howtos/x200_pxe_e05.html link PXE-E05]

For Gentoo users - compile e1000 as a kernel module and add 'options e1000 InterruptThrottleRate=0,0' to /etc/modules.d/e1000

I had serious performance problems on Ubuntu Edgy (ca. 400 kb/s File transfer rate).
I compiled version e1000-7.3.20 from http://sourceforge.net/projects/e1000/ and this solved my problem.
All other hints above did not improve the file transfer performance (they did improve the ping latency) for me.

=== Broadcom Fast Ethernet (10/100) ===
Driver: [[tg3]] or [[bcm5700]]

This chip is integrated into select systemboards of the following machines: 
'''Broadcom BCM5901'''
* {{G40}}, {{G41}}
* {{R40e}}
'''Broadcom BCM5751F'''
* {{R51e}}

=== Broadcom Gigabit (10/100/1000) ===
Driver: [[tg3]] or [[bcm5700]]

This chip is integrated into select systemboards of the following machines:

'''Broadcom BCM5752M'''
* {{Z61e}}

'''Broadcom BCM5751M'''
* {{R52}}, {{R60}}
* {{G41}}
* {{T43}}, {{T43p}}
* {{X41}}, {{X41T}}
* {{Z60m}}, {{Z60t}}
* {{Z61m}}, {{Z61p}}

Note: There are some problems with the driver since kernel 2.6.17 (at least on a Z61p, Z61m). After an ifdown && ifup it doesn't work anymore. A possible workaround is to build the tg3-driver as a module and reload it when this problem occours. (Adding ''pre-up modprobe tg3'' and ''post-down rmmod tg3'' to the corresponding section in /etc/network/interfaces works fine.) Rebooting the machine would also be possible.
This is fixed in kernel 2.6.19-rc5.

The T43 with a stock Linux 2.6.18.1 kernel does not have any problems.
