mv643xx_eth: shrink default receive and transmit queue sizes
Since the size of the receive queue is directly related to the data cache footprint of the driver (between refilling a receive ring entry with a fresh skb and receiving a packet in that entry, queue_size - 1 other skbs will have been touched), shrink the default receive queue size to a saner number of entries, as 400 is definite overkill for almost all workloads. While we are at it, trim the default transmit queue size a bit as well. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
