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. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
