Bug #7975
closeddpdk: CPU exclude logic is broken
Description
The exclude logic incorrectly performs the XOR operation. While it works when the worker cores occupy all cores, it is still not a correct operation.
The example might be when a core is affined to only management and not worker threads. With the XOR operation, it would set the affinity to the worker set.
(1 XOR 0 -> 1, where in fact the desired outcome is 0)
