When the DMA table has been allocated dynamically, the IOCTL_SET_PACKETSIZE will trigger an issue where pDev->rx and pDev->tx are not updated with the new DMA tables base address. Instead the old pointers are used. There is no point in reallocting the DMA tables because there is no configuration option to it. Therefore the DMA tables allocation is moved to a separate function never called from SET_PACKETSIZE.
