I think netisr code should be fixed, we even have in the comment suggested
solution: DPCPU_ID_GET(nws_array[arbitraryvalue % nws_count], nws)
So, probably if we define macro:
#define NETISR_WS(_cpuid) DPCPU_ID_GET(nws_array[(_cpuid) % nws_count], nws)
Then replace all DPCPU_ID_GET(xxx, nws) with NETISR_WS(xxx), I think this will
help. But, maybe Robert or Adrian will suggest something better.
