#Intel i210 driver source code

Other optionsД®nable multiqueue in 2.6.27 and newer kernels.'ДЄnd also looked in the code within kcompat.h: 'CONFIG_NETDEVICES_MULTIQUEUE only exists from 2.6.23 to 2.6.26. I've also checked for CONFIG_NETDEVICES_MULTIQUEUE - google tells that: What are the other kernel / platform dependencies needed for AVB feature? So, if the MSI-X is manadatory for I210 AVB features we need to see into Xilinx PCIe first. There are some collisions in Xilinx documentation for that and some explanations from Xilinx needed. I'm not sure that Xilinx PCIe is fully compliant with MSI-X.

Is MSI-X compatibility mandatory for IGB AVB-customed version (AVB functionality)?

Possibly there are some known fixups/patches to get igb_avb working on ARM etc. Has anyone successfully ported and used IGB AVB driver on ARM platform? Now we have some few questions for further development within igb_avb: So, need to investigate igb_avb source code - possibly some defines are missed or something else related to arm linux needs to be fixed and so on. Looking at igb_avb kcompat.h and Makefile shows some dependencies on kernel version and features, linux distribution etc - which is not present in standard igb driver from linux 4.0 kernel. The module is well probed and ETH is instantiated: also using legacy interrups, failed to initiaze MSI/MSI-X interrupts (same as mainline igb driver - needs further research also for FPGA PCIe core + drivers).Д«ut unlike the standard igb driver, after bringing up the ETH looses any TX/RX packets (showing the link is up at 1000Mb/s).Дiff for the igb_avb source with the standard igb driver from linux 4.0 kernel shows a plenty of changes/differences. We've cross-compiled igb_avb driver successfully. So, now we are trying to get igb_avb kernel module (AVB-customed version of the Intel igb driver) working for our ARM based platform. We've got igb driver from mainline kernel (xlnx-4.0 linux kernel) working (at least in legacy mode for now). It's supposed to communicate with Intel I210 Ethernet adapter card via FPGA PCIe IP core (axi_pcie). We are trying to port Intel I210 based Open AVB project into Xilinx Zynq ARM based platform.
