Did it work with in-kernel driver? There is only one remotely related change in the driver: - mta = ioread32((hw + REG_RX_HASH_TABLE) + (hash_reg << 2)); + mta = ioread32((hw->hw_addr + REG_RX_HASH_TABLE) + (hash_reg << 2)); If it worked before, then spurious ioread() from outside of our univercity could lead to good/bad mta value (likely zero or ~0), so appropriate multicast list update could succeed. If your programs never worked with this new driver, then it can not be easily solved without hardware specifications. I added Jay Cliburn who submitted the driver to Cc list. > Jose Alberto -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
