From ef12ad45880b696eb993d86c481ca891836ab593 Mon Sep 17 00:00:00 2001 From: Karsten Graul Date: Wed, 14 Oct 2020 19:43:28 +0200 Subject: net/smc: fix valid DMBE buffer sizes The SMCD_DMBE_SIZES should include all valid DMBE buffer sizes, so the correct value is 6 which means 1MB. With 7 the registration of an ISM buffer would always fail because of the invalid size requested. Fix that and set the value to 6.
