This series fully update existing ISOC DDMA flow which initially based on
2 descriptor chains. Switching between desc chains performing based on BNA
interrupt. Because of BNA interrupt few packets can be lost.

Changed existing two descriptor-chain flow to one chain.
In two-chain implementation BNA interrupt used for switching between
two chains. BNA interrupt asserted because of returning to
beginning of the chain based on L-bit of last descriptor.
Because of that we lose packets. This issue resolved b
Updated checking of chain full condition based on mult count.
For each packet in uframe (dpi) created new desc by
