registers.

a89ce48ab2 nvethernetrm: Indicate more Rx frames pending 
Issue: The function osi_process_rx_completions does
       not provide indication whether there are more
       Rx frames in the HW ring to be processed by SW.
       This indication is needed in OSD layers like
       AUTOSAR MCAL driver as per the spec.
Fix:   Check the next descriptor in the ring and indicate
       if it has a valid new Rx packet that is pending
       to be processed.

9f4bff9f10 osi: dma: Add callback for osd data path 
Issue:
When 2 OSD's are part of single compilation process, only one
OSD can be linked at compile time. This causes issues in handling
TX and RX communication from OSI to OSD.

Fix:
Add callbacks for TX and RX communication which can be registered by
OSD to receive callback communication from OSI for TX and RX. Use
existing API's if OSD doesn't register a callback.

	vm_irq1 {
		nvidia,num-vm-channels = <2>;
		nvidia,vm-channels = <0 1>;

2df2d68dce nvethernetrm: Add API to backup/restore registers 
Issue: During SOC suspend, the MAC is placed in reset.
       This causes all dynamic configurations done by
       SW on the MAC core registers is lost. When SOC
       resumes, MAC is initialized to power-on-default
       configuration, while other SW components still
       have previously set configuration. This results
       in mismatch between HW/SW configuration.
Fix:   Add APIs osi_save_registers(), osi_restore_registers()
       to backup and restore the MAC core configuration
       registers before suspend and after resume respectively.

bba8383678 nvethernetrm: Honor budget for processing tx completions 
Issue: osi_process_tx_completions is run in the BH for
       processing Tx done irq. This function always loops
       till the Tx status for all packets that are Tx'd so
       far is processed.
       1) The NAPI budget for this Tx completions handler is
       not honored.
       2) The variable 'processed' is expected to keep track
       of Tx'd packets. Currently it is counting Tx'd descriptors.
       There can be multiple Tx descriptors consumed for one packet.

Fix: 1) Add budget parameter to osi_process_tx_completions() API.
     2) Break out of loop in this API if packets to process
        exceeds budget
     3) Increment the processed count variable only after checking
        last descriptor for a packet.

Receive timestamp for a received packet will be in context descriptor
which is immediate of normal descriptor (has valid packet data)
In current case nvethernet driver only unmap normal descriptor buffer
address and provide the buffer to the network stack for data processing.
Context descriptor buffer is not unmapped which leads to running out of
IOVA space for the new buffers.

Context descriptor buffer can be used as is since that is not provided
to the network stack. So this change to a flag for context descriptor.
Based on this flag OSD can skip new buffer allocation and mapping for
the context descriptor and use already allocated buffer.
