#4304: leon,grspw: SET_PACKET_SIZE could use old DMA address
  Reporter:  Daniel Hellstrom  |      Owner:  Daniel Hellstrom
      Type:  defect            |     Status:  assigned
  Priority:  normal            |  Milestone:  6.1
 Component:  admin             |    Version:  5

Blocked By:                    |   Blocking:
 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.
