The DM9000A network controller does not work with the U-boot DM9000x driver. Analysis showed that many incoming packets are lost. The DM9000A Application Notes V1.20 (section 5.6.1) recommend that the poll to check for a valid rx packet be done on the interrupt status register, not directly by performing the dummy read and the rx status check as is currently the case in the u-boot driver. When the recommended poll is done as suggested the driver starts working correctly on 10Mbit/HD, but on 100MBit/FD packets come in faster so that there can be more than 1 package in the fifo at the same time. The driver must perform the rx-status check in a loop and read and handle all packages until there is no more left _after_ the interrupt RX flag is set. This change has been tested with DM9000A, DM9000E, DM9000EP. Signed-off-by: Remy Bohmer <linux@bohmer.net> Signed-off-by: Ben Warren <biggerbadderben@gmail.com> |
