From c5057ddccbcb4bf363af628d7963a7475f4114a7 Mon Sep 17 00:00:00 2001 From: Oren Duer Date: Mon, 5 May 2008 15:56:52 -0700 Subject: [PATCH] mlx4_core: Support creation of FMRs with pages smaller than 4K Don't hard code a test against a minimum page shift of 12, since the device may support smaller pages. Test against the actual smallest page size from the device capabilities.
