[yocto] [PATCH 1/3] [meta-intel] meta-intel/common:Add a new recipe for Zlib qat_mem Module.

Fri Oct 19 11:34:37 PDT 2012

Hi Kishore,

I've built these and they look ok as far as that goes.

But I'm wondering, which kernel did you test with and which kernel(s)
are these modules designed for i.e. will they work with all the kernels
supported for 1.3?
