Thank you very much. FIX_TXDESC_ATOMIC will fix a bug that nic may not read tx descriptors correctly because flags in tx descriptors were not set atomic. I found the issue just several days. This is a reasonable result, I think. As the other flags below seemed to be no effect, I'd like to withdraw them. FIX_SMALL_BUFFERS FIX_COMMAND_REG FIX_DMA_UNLIMIT Now the problems became clear very much. Thanks again.
