No I didn't test big endian in the guest.
I don't have any big endian VM image. Is it required for the
test? I mean, is it possible to run a big endian DPDK userland
application on a little endian kernel? (and if yes, is it
known to work?)
Maybe I could replace in the patch:
#ifdef RTE_ARCH_PPC_64
By something like :
#if defined(RTE_ARCH_PPC_64) && (RTE_BYTE_ORDER == RTE_LITTLE_ENDIAN)
If you have the ability to test it easily, it would be appreciated :)
Thanks for the review!
Olivier
