The unit test of table got failed.
When I took a look at the code, it failed on this line in file
lib/librte_table/rte_table_hash_key8.c ,
lib/librte_table/rte_table_hash_key16.c,
lib/librte_table/rte_table_hash_key32.c:

Refer to FW default setting, Ethertype 0x88A8 is treated as S-TAG,
packects with S-TAG should be received in Port Virtualizer mode,
but Port Virtual mode is not initialized in DPDK. So X710 will
packets with Ethertype 0x88A8.
This patch fixes this issue by turning off S-TAG identification.
Fixes:
This patchset enables LPM, ACL and other few missing libs in ppc64le and also
address few patches in related examples (ip_pipeline and l3fwd).
Test report:
1. LPM and ACL unit tests passed.
Steps:
compile test app and run (with any needed params)
lpm_autotest
acl_autotest
This patch adds port for ACL library in ppc64le.

This patch optimizes the vhost enqueue function: rte_vhost_enqueue_burst.
Currently there're 2 callbacks for vhost enqueue:
* virtio_dev_merge_rx for mrg_rxbuf turned on cases.
* virtio_dev_rx for mrg_rxbuf turned off cases.
The virtio_dev_merge_rx doesn't provide optimal performance, also

Hello,
In our application we need to be able to allocate tens of thousands of ACLs at
runtime.
Testing revealed significant performance problems. We were able to track them
to memset in calloc function which caused multiple page walks per invocation.
Modifying tb_mem to use huge page memory
Acl build process uses significant amount of memory
which degrades performance by causing page walks when memory
is allocated on regular heap using libc calloc.
This commit changes tb_mem to allocate temporary memory on huge pages
with rte_calloc.

On Linux, all huge pages are zeroed by the kernel before
first access by the DPDK application. But on FreeBSD,
the contigmem driver would only zero the contiguous
memory regions during initial driver load.

Patch 1: rename the CLI option "dev-basename".
Patch 2: add multiple socket files support.

In examples/vhost, "dev-basename" is a program option, which is to set
the vhost-net socket used by vhost-user, or the character device used
by vhost-cuse. Since vhost-cuse should be dropped, and "dev-basename"
is not a suitable name for the vhost-net socket. Therefore, this patch
is to change
