From c50037496113e2eb04cfeec86a5c2490786c3dd5 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Sat, 28 Jul 2012 11:39:48 -0500 Subject: [PATCH] staging: r8712u: Reduce maximum receive buffer size to a more sensible value The current value for the maximum receive buffer size is 30720, which is too large. For long-running systems, memory fragmentation may make it difficult to obtain the buffers of O(2) needed for aggregation. Buffers of O(3) are even worse, particularly when not needed. The new size is set to 9100, which will allow aggregation.
