In Omnet++, TSN devices use layered Ethernet Interface and standardHosts use Ethernet Interface.
What is the difference between these two interfaces?

Do Omnet++ and Inet 4 and above support multi-radio interfaces for wireless nodes such as Adhoc nodes? One of its applications, simulating wireless nodes for estimating self-interference. Another application is simulating multi-channel wireless networks.
Yes it does, as the following tutorial shows
(BTW, multiple wireless interfaces are also supported in INET 3.x)
I have zynq with carrier board. This board has a ethernet port, but I need two ports. Can I create new ethernet port with fpga IO pins. Is it possible or do have any different idea about that?
My board is Picozed FMC Carrier.
Short: No!
An ethernet interface is a special type of analogue interface with lots and lots of special circuitry on it. You can NOT get the right behavior with a digital interface.
If your FPGA has a USB port you might try to add a USB <=> Ethernet converter chip to get a second Ethernet port. (like all the old Raspberry-Pi's have).
I'm looking to write a simple Windows driver to enable running TCP/IP over a proprietary RF module. The module already provides Ethernet-style data packets with source/destination MAC, so I just need to layer IP packets (generated by the regular Microsoft IPv4 subsystem), set the MTU appropriately so they will be the right size, and then call the module's serial API. I'll need to be able to handle transmit statuses and implement an ARP protocol as well. I want the driver to expose a new interface similar to a wifi or ethernet card in Network Connections and use the normal Windows IP stack.
The module is UART and might be connected via FTDI chip, RS-232 converter, or native UART on an IoT Core board, so it will just be talking to a generic serial port. I am fine with only running on Windows 10, but I'm still not sure what to use. Can I use the UWP VPN provider? Do I need to write an NDIS miniport driver, or an interface provider? Also, how will I handle the driver needing complete control over the serial port at all times? I can't write a serial driver as it might be connected via many different types of serial ports.
I am working on the lowRISC recently, and I want to add Ethernet support for it. I have added the Ethernet IP and have wired it to both AXI bus and Ethernet PHY, and I added the Ethernet interrupt to the interrupt wire just like uart and spi do.
Now I am working to write a driver in linux kernel to support my Ethernet. But I don't find the handle functions to uart and spi interrupts, just 2 interrupts called IRQ_SOFTWARE and IRQ_TIMER(which in file arch/riscv/include/asm/irq.h).
How does the lowRISC chip handle the uart and spi interrupts? And What should I do to handle the interrupt of ethernet on lowRISC chip?
I am confuse among various interfaces of ethernet .I am just going through this U-Boot Link
http://www.denx.de/wiki/DULG/UBootEnvVariables
Where it says
ethaddr: Ethernet MAC address for first/only ethernet interface (= eth0 in Linux).
Now my confusion is eth0 is only real interface whose address is programmed into efuse register
Is other interfaces like eth1 ,eth2 and so on virtula interface which will be configured by applcation later on .
Also from this link
http://e2e.ti.com/support/arm/sitara_arm/f/791/t/209421.aspx
Where it says
The MAC addresses programmed into the internal e-fuses will be from the TI address pool. Customer will need to add some type of storage device (Flash, EEPROM) which contains their MAC addresses if they want to use addresses from their own address pool.
Now are these two mac address one written in e-fuse and other in Flash by customer two different address for eth0?
This uboot documentation is for many different kinds of hardware, some of which have only 1 interface, and some of which have more. The language "Ethernet MAC address for first/only ethernet interface (= eth0 in Linux)" just means that referenced variable is for eth0, which is the first ethernet interface. If there is only one interface, it is still called eth0. If your hardware has multiple ethernet interfaces, the other variables are for them.
Regarding the second question: it appears that this hardware device has a built-in ethernet controller, which needs a unique MAC address to function on a network. The device ships with a MAC address already configured (written into the e-fuse of the device, and therefore read-only). If you don't want to use that MAC address, you can instead use flash or EEPROM to store your own MAC address to configure the ethernet controller. Only one of those choices will be active.
One reason you might want to change the MAC address is that MAC addresses are assign in blocks to different vendors, and the shipped address is from the TI block. That means network analyzers will think the overall product is a TI device. If you want your product to appear as a different vendor, you need to use your own MAC address drawn from your own pool. If you don't know what this means, don't worry about it: use the one that is preconfigured and built-in.
