From 2391b0030e241386d710df10e53e2cfc3c5d4fc1 Mon Sep 17 00:00:00 2001 From: Arjun Vynipadath Date: Fri, 16 Nov 2018 09:15:42 +0530 Subject: [PATCH] cxgb4: Remove SGE_HOST_PAGE_SIZE dependency on page size The SGE Host Page Size has nothing to do with the actual Host Page Size. It's the SGE's BAR2 Doorbell/GTS Page Size for interpreting the SGE Ingress/Egress Queue per Page values. Firmware reads all of these things and makes all the subsequent changes necessary. The Host Driver uses the SGE Host Page Size in order to properly calculate BAR2 Offsets.
