skge: FIFO Ram calculation error
The calculation of usable FIFO RAM is wrong in the skge driver. First, is doesn't take into account the reserved area on the original SysKonnect Genesis boards. Second it has an off-by-one error because hw->ports is either 1 or 2. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
