[dpdk-dev] [PATCH dpdk 0/5] ppc64/spapr: Attempt to use on POWER8

[Alexey Kardashevskiy]

Hi!

This is my first attempt to use DPDK on POWER8 machine and yet
unsuccessful as it turned out DPDK only supports IB-Mellanox
(I only got ethernet-Mellanox, and requires OFED), rmmod on
Intel 40Gb module produces PCI errors (unrelated to DPDK) and
Broadcom bnx2x has few issues (below) and still crashes as
I suspect I got DMA mapping wrong, here is a backtrace:

Configuring Port 0 (socket 0)
PMD: bnx2x_issue_dmae_with_comp(): DMAE timeout!

Thread 1 "testpmd" received signal SIGABRT, Aborted.
0x00003fffb7c3edb0 in __GI_raise (sig=<optimised out>) at ../sysdeps/unix/sysv/linux/raise.c:54

Still, some fixes are quite obvious and straigtforward.

This is based on sha1

Please comment. Thanks.
