Hi All,
When I use the network Drivers provided by the API is the CRC error checking done by the hardware. Or is to be taken care by the software. I do not see any of the example APIs doing . So I just wanted to ask it.
Thanking you,
Param

We have a number of checksum the FCS (Frame Checksum) is normally done by the NIC plus FCS errors normally do not transfer the frame into memory. The other Checksums UDP, IP, TCP are done in hardware and software depending on the NIC being used. Need to read the docs for the NIC and then look at the config or setup of the RX/TX for that NIC in the example applications.

Hi All,
I find that DPDK provides the Multiqueue support depending on the number of queues in the Hardware. So in case I need an application where I need the order of the packet transmitted or received not to change using multiple queues require the application to maintain the synchronisations. So is the take right from the Mutiqueue point of view.
Thanking You,
Param.
