Subject: ivshmem: add all memzones of mempool to metadata
X-Git-Tag: spdx-start~6836
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ca173a909538a2f1082cd0dcb4d778a97dab69c3;p=dpdk.git

ivshmem: add all memzones of mempool to metadata

Mempool consist of multiple memzones, at least from two of them.
ivshmem assumes mempool and elements are all in same memzone.

Updating code to add all memzones when a mempool added.

Fixes: d1d914ebbc25 ("mempool: allocate in several memory chunks by default")
