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...
1) My Example program code

}
2) My Example Driver code

Hello,
Searched in all IBM Redbooks and on the internet and couldn't find anything about the new feature of POWER 6 which Virtual Fibre ( Fiber ) channel adapter.
It is similar to virtual scsi adapter.
In my client partition I created the virtual Fibre Adapter mapped it with the VIO... (1 Reply)

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:
HSCL068A
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:

// copy of Telnet data struct
UINT uSize;
// basic properties:
TCHAR szHost; //defined in Sshconfig
UINT iPortNr;

Hello, hopefully someone can help me out with this, I have created a virtual Ethernet adapter on the VIO but would like to add it to my new LPAR.
On my VIO only my disk is mapped.

I installed Solaris 11.1 on a X86 PC. It's working except for one glaring problem : I cannot get a driver attached to the RaLink RT2800 (Wi Fi Adapter). Can someone point me in the direction where " the correct" driver exists, or let me know how I can tell Solaris to attach the device to the... (1 Reply)

MEMBERS
wiphy
pointer to hardware description
iftype
interface type
list
(private) Used to collect the interfaces
netdev
(private) Used to reference back to the netdev, may be NULL
identifier
(private) Identifier used in nl80211 to identify this wireless device if it has no netdev
mgmt_registrations
list of registrations for management frames
mgmt_registrations_lock
lock for the list
mtx
mutex used to lock data in this struct
cleanup_work
work struct used for cleanup that can't be done directly
use_4addr
indicates 4addr mode is used on this interface, must be set by driver (if supported) on add_interface BEFORE registering the netdev and
may otherwise be used by driver read-only, will be update by cfg80211 on change_interface
p2p_started
true if this is a P2P Device that has been started
address[ETH_ALEN]
The address for this device, valid only if netdev is NULL
ssid[IEEE80211_MAX_SSID_LEN]
(private) Used by the internal configuration code
ssid_len
(private) Used by the internal configuration code
mesh_id_len
(private) Used by the internal configuration code
mesh_id_up_len
(private) Used by the internal configuration code
wext
(private) Used by the internal wireless extensions compat code
DESCRIPTION
For netdevs, this structure must be allocated by the driver that uses the ieee80211_ptr field in struct net_device (this is intentional so
it can be allocated along with the netdev.) It need not be registered then as netdev registration will be intercepted by cfg80211 to see
the new wireless device.
For non-netdev uses, it must also be allocated by the driver in response to the cfg80211 callbacks that require it, as there's no netdev
registration in that case it may not be allocated outside of callback operations that return it.
