>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.
