Subject: [dpdk-dev] [PATCH] net/mlx5: fix number of retries for UAR allocation
Date: Mon,  3 Aug 2020 12:18:27 +0300	[thread overview]
Message-ID: <70ff61d3d8431aeb73ee5c5c23c87e525dc221ec.1596446316.git.dekelp@mellanox.com> (raw)

Previous patch added definition of number of retries for UAR allocation.
This value is adequate for x86 systems with 4K pages.
On power9 system with 64K pages the required value is 32.
This patch updates the defined value from 2 to 32.
