Subject: net/mlx5: Decrease default mr cache size
From: Artemy Kovalyov <artemyko@xxxxxxxxxxxx>
[ Upstream commit e8b26b2135dedc0284490bfeac06dfc4418d0105 ]
Delete initialization of high order entries in mr cache to decrease initial
memory footprint. When required, the administrator can populate the
entries with memory keys via the /sys interface.
This approach is very helpful to significantly reduce the per HW function
memory footprint in virtualization environments such as SRIOV.
