Subject: net/mlx: remove unused memory region property
X-Git-Tag: spdx-start~6526
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6e0eab380206a9ff0e40ce571818295b49aadb63;hp=b6d5fd2e96096390faeface25ee56f841763c169;p=dpdk.git

net/mlx: remove unused memory region property

Memory regions are always local with raw Ethernet queues, drop the remote
property as it adds extra processing on the hardware side.
