            Bug ID: 1704
           Summary: CPU_SETSIZE should not be used
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev at dpdk.org
          Reporter: mb at smartsharesystems.com
  Target Milestone: ---

The EAL assumes that cpu_set_t is an array holding CPU_SETSIZE elements.
This doesn't work when the host has more physical CPU cores than CPU_SETSIZE.

Instead, it should use CPU_ALLOC()/CPU_FREE() with the correct number of
physical CPU cores in the host.
