rte_efd_create() function was using uint8_t for a socket bitmask,

This limits the maximum of NUMA sockets to be 8.
Changing to to uint64_t increases it to 64, which should be
more future-proof.
Cc: ppc maintainer, since I think powerX servers have non contiguous
NUMA sockets.
Definitely correct, POWER CPU NUMA sockets are not necessarily contiguous.
Can you update efd_autotest and efd_perf_autotest as well? After
applying this patch the test still fails on my POWER9 system:
$ sudo /home/drc/src/dpdk/build/app/test/dpdk-test -l 64-127 -n 4 --no-pci
...
RTE>>efd_autotest
Entering test_add_delete
EFD: At least one CPU socket must be enabled in the bitmask
EAL: Test assert test_add_delete line 125 failed: Error creating the EFD
table
Test Failed

On this system lcores 64-127 reside on NUMA socket 8.
