From: Saeed Mahameed <saeed@kernel.org>
Date: 2022-09-27 20:37:00
Subsystem:
mellanox mlx5 ib driver, mellanox mlx5 core vpi driver, the rest · Maintainers:
Leon Romanovsky, Saeed Mahameed, Tariq Toukan, Mark Bloch, Linus Torvalds
From: Maxim Mikityanskiy <redacted> Add the capability that will allow the driver to determine the minimal MTT page size to be able to map the smallest possible pages in XSK. The older firmwares that don't have this capability default to 12 (i.e. 4096-byte pages).
