First, sorry about the so-so topic for the kernel developers...but still there are such things inside :)
Currently I am investigating how "they" divide those polynomials and which possibilities exists to use SIMD for such calculations. I have found several papers about how to do it with Altivec and my question is: does anybody knows about efforts to use Altivec for CRC calculations here? Topic itself is quite old...
Or is there just any other ongoing developments which implements for example permute/shuffle instructions (Altivec: vperm/SSE2: pshufd) for table lookups?
One more question: is there PCI/PCIe cards (eg. router) which implements Layer 3(-4) in hardware and which are possible to use as "hardware net accelerator"?
thanks, Indrek
