Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port. To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports.

When a parallel port (lowlevel) driver finds a port that should be made available to parallel port device drivers, it should call parportregisterport.The base, irq, and dma parameters are for the convenience of port drivers, and for ports where they aren’t meaningful needn’t be set to anything special. When an application opens a port (using CreateFile), it appends an additional part to the device name string to specify which port on the device it is opening, e.g. The driver will then receive an IRPMJCREATE IRP and will be able to retrieve the extended part of the device name from the FileName member of the.

The Ethernet switch device driver model (switchdev) is an in-kernel drivermodel for switch devices which offload the forwarding (data) plane from thekernel.

Figure 1 is a block diagram showing the components of the switchdev model foran example setup using a>FIB_EVENT_ENTRY_ADDused for both adding a new FIB entry to the device,or modifying an existing entry on the device.FIB_EVENT_ENTRY_DELused for removing a FIB entryFIB_EVENT_RULE_ADD,FIB_EVENT_RULE_DELused to propagate FIB rule changes

Routes offloaded to the device are labeled with “offload” in the ip routelisting:

The “offload” flag is set in case at least one device offloads the FIB entry.

Nexthop Resolution¶

The FIB entry’s nexthop list contains the nexthop tuple (gateway, dev), but forthe switch device to forward the packet with the correct dst mac address, thenexthop gateways must be resolved to the neighbor’s mac address. Neighbor macaddress discovery comes via the ARP (or ND) process and is available via thearp_tbl neighbor table. To resolve the routes nexthop gateways, the drivershould trigger the kernel’s neighbor resolution process. See the rockerdriver’s rocker_port_ipv4_resolve() for an example.

The driver can monitor for updates to arp_tbl using the netevent notifierNETEVENT_NEIGH_UPDATE. The device can be programmed with resolved nexthopsfor the routes as arp_tbl updates. The driver implements ndo_neigh_destroyto know when arp_tbl neighbor entries are purged from the port.

If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. Take into consideration that is not recommended to install the driver on Operating Systems other than stated ones.

In order to manually update your driver, follow the steps below (the next steps):

1. Extract the .cab file to a folder of your choice

2. Go to Device Manager (right click on My Computer, choose Manage and then find Device Manager in the left panel), or right click on Start Menu for Windows 10 and select Device Manager

3. Right click on the hardware device you wish to update and choose Update Driver Software

4. Choose to select the location of the new driver manually and browse to the folder where you extracted the driver

5. If you already have the driver installed and want to update to a newer version got to 'Let me pick from a list of device drivers on my computer'

6. Click 'Have Disk'

7. Browse to the folder where you extracted the driver and click Ok

About Keyboard Driver:

Install the proper keyboard software and your system will be able to recognize the device and use all available features. This will also make it possible for owners to configure additional hotkeys.

In case additional keyboard accessories are connected, this step can also improve the bundle’s overall stability and compatibility, as well as performance.

Therefore, if you wish to install this release, simply make sure that your computer OS is supported, save the package, extract it if necessary, run the available setup, and follow the on-screen instructions for a complete installation.

Bear in mind that, even though other platforms might be compatible, we do not recommend applying this software version on configurations running under OSes other than the specified ones.
