Yes, I have made a little research and found that net_device struct is a little bit different since 2009. I am trying to fit this code to new net_device struct that is no so easy.
Have you got any samples of network drivers basic source code?
I got now:
I can compile it, but if I type 'insmod mymodule' then segmentation fault occurs. Don't know solution.
Hi, everybody
I have next problem...

Hi all, I got sort of a task to do. I have to write in C "simulated network driver". What does it mean?
- It has to run on all network adapters
- It has to be as simple as it can be
- It has to run on all linux distributions (or at least most of them)
- It does not have to run a network... (4 Replies)

I am trying allocate an IVE to an LPAR (not a VIO) running AIX 7.1. I am getting the error:

Explanation
Logical port can not be assigned to Logical Partition because this Logical Partition is not the promiscuous LPAR for the physical port.
Has anyone encountered this... (1 Reply)
Hi,
I have received an application that stores some properties in a file. The existing struct looks like this:

EPAIR(4) BSD Kernel Interfaces Manual EPAIR(4)NAME
epair -- A pair of virtual back-to-back connected Ethernet interfaces
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device epair
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_epair_load="YES"
DESCRIPTION
The epair is a pair of Ethernet-like software interfaces, which are connected back-to-back with a virtual cross-over cable.
Each epair interface pair is created at runtime using interface cloning. This is most easily done with the ifconfig(8) create command or
using the cloned_interfaces variable in rc.conf(5). While for cloning you only give either epair or epair<n> the epair pair will be named
like epair<n>[ab]. This means the names of the first epair interfaces will be epair0a and epair0b.
Like any other Ethernet interface, an epair needs to have a network address. Each epair will be assigned a locally administered address by
default, that is only guaranteed to be unique within one network stack. To change the default addresses one may use the SIOCSIFADDR ioctl(2)
or ifconfig(8) utility.
The basic intend is to provide connectivity between two virtual network stack instances. When connected to a if_bridge(4) one end of the
interface pair can also be part of another (virtual) LAN. As with any other Ethernet interface one can configure vlan(4) support on top of
it.
SEE ALSO ioctl(2), altq(4), bpf(4), if_bridge(4), vlan(4), loader.conf(5), rc.conf(5), ifconfig(8)HISTORY
The epair interface first appeared in FreeBSD 8.0.
