Do you have plan support Packet acquisition via PF_RING

[utoni]

It was planned some time ago, but I had no use for it at that time. But times changed and if there is someone else who needs this...

I'll put this on ToDo for 1.7

[outbackdingo]

yupp with the higher-end 10gb capable routers coming out now, be good for nDPId w/ PF-RING to work on openwrt....

[utoni]

I am currently investigating PF_RING API. I am making some progress, but need a bit more time until this feature is kinda stable.

@triplekill @outbackdingo

nDPId has now experimental PF_RING support. Please checkout PR #38 and give me some feedback, bug reports, stability issues etc.

[outbackdingo]

Great to see, Ive looked at the code, think you can maybe sanity check the Makefile for OpenWRT ... building for ARM

[utoni]

That's something I need to investigate. I did not touch any OpenWrt Makefiles. In essence, what we need to do here is to set PFRING_KERNEL_INC to the kernel header directory and PFRING_INSTALLDIR to the install directory of PF_RING / libpfring. There is a better way to do this e.g. w/o any user interaction required, but need to think about it.

[utoni]

@outbackdingo Please take a look at packages/openwrt/net/nDPId-testing/Makefile in #38. It's now possible to build nDPId for OpenWrt with PF_RING enabled.

[utoni]

(Experimental) Support merged to main. See #38.
