kse -- Micrel 8842/8841 PCI Ethernet controller driver
SYNOPSIS
kse* at pci? dev ? function ?
DESCRIPTION
The kse driver supports Ethernet interfaces based on the Micrel 8842/8841 PCI Ethernet chips. The 8842 has 2 Ethernet ports which behave as
a managed switch to bridge each other. It works like a T-shape connector of Ethernet data flow in which an Ethernet controller sits at the
leg of the T. Frames can flow between the two ports while traffic destined for the 8842 reaches the EMAC. The 8841 is a plain 10/100 Ether-
net. The kse driver distinguishes and handles them according to the HW model.

The kse driver was written by Tohru Nishimura.
BUGS
__STRICT_ALIGNMENT case is not written. 8842 media selection keeps ``auto'' and indicates ``up 100baseTX-FX flow'' when either of two ports
is found link-up. There is no functional provision to see and control the media selection of them this moment. Advanced features like flow
volume bound, VLAN tag insertion/removal, QoS DiffServ are not implemented and remain uncontrollable by the kse driver. UDP4CSUM is not very
useful since the HW has an implementation error for the case when a large UDP datagram is fragmented into MTU sized frames.

pcn -- AMD PCnet-PCI Ethernet family driver
SYNOPSIS
pcn* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See mii(4).
DESCRIPTION
The pcn device driver supports Ethernet interfaces based on the AMD PCnet-PCI family of Ethernet chips. The chips supported by the pcn
driver include:
o Am79c970 PCnet-PCI Single-Chip Ethernet Controller for PCI Local Bus
o Am79c970A PCnet-PCI II Single-Chip Full-Duplex Ethernet Controller for PCI Local Bus
o Am79c971 PCnet-FAST Single-Chip Full-Duplex 10/100Mbps Ethernet Controller for PCI Local Bus
o Am79c972 PCnet-FAST+ Enhanced 10/100Mbps PCI Ethernet Controller with OnNow Support
o Am79c973/Am79c975 PCnet-FAST III Single-Chip 10/100Mbps PCI Ethernet Controller with Integrated PHY
PCnet-PCI chips are found on some Hewlett-Packard PCI Ethernet boards, and on the Allied Telesyn AT-2700TX PCI Ethernet board. They are also
found on some processor evaluation boards as an example peripheral.
The pcn driver also supports the emulated PCnet-PCI interface provided by VMware.
SEE ALSO arp(4), ifmedia(4), mii(4), netintro(4), pci(4), ifconfig(8)HISTORY
The pcn driver first appeared in NetBSD 1.6.

I have a Quad Ethernet card in a 220R. 2 ports activated. Each has its own hostname file and both hostnames are in the hosts file. I want both ports to have the same IP address so we can use the 2nd port in case we lose communication on the port. On bootup, the box gives me:

I have a new Sun 440 and I am trying to configure it. Non of the Ethernet ports are enabled; when I issue "ifconfig -a" it returns nothing. Is there a way to know the available port name (e.g. ce, bge, etc.) by running a command or so ? (4 Replies)
Hi,
I have a AIX5.3 P6-520 with 8x1Gb Ethernet ports with possible connections to 2 CISCO 2960 switches.
I can create 8023ad Etherchannels which work correctly with the switches (I have set up for LACP passive and a valid channels)
But can create 2x 8023ad 4Gb Etherchannels with no backups.... (2 Replies)
on a p5 520, running aix 7.1 with the latest TL and SP..
had a 133 MHz Sun PCI 1G or quad 4 x 100 Meg Ethernet card installed..
but it shows unknown type using using lscfg or lsslot
Is there addtional drivers to be installed ???

Hello Everyone,
Quick question, any short and fast way to locate and map the physical Ethernet ports on the physical server ?
Server with expansion box has around 12 ethernet ports (fibre and ethernet)
what is the quickest way to map or find out en0 represents which physical port ?

I have a server with 6 Ethernet ports. 4 are the the motherboard based 1 GBE ports and 2 are 10 GBE ports on NICs.
I have set these all up with static IP addresses and use the standard /etc/nsswitch.files. My IP addresses are
net0 192.168.1.82
net1 192.168.2.82
and so on till
