[PATCH net-next 3/5] net: mvpp2: use a data size of 10kB for Tx FIFO on port 0

From: Yan Markman This patch sets the Tx FIFO data size on port 0 to 10kB. This prepares the PPv2 driver for the Jumbo frame support addition as the hardware will need big enough Tx FIFO buffers when dealing with frames going through an interface with an MTU of 9000.
