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.

e2c9e7e3cb nvethernetrm: Add slot function support 
Issue:
Data packets sent via EQOS hardware are not
following any packet gaping. The AVB use-cases
have different timing requirements for class A
data packets. For example, the time difference
between two class A data packets are supposed
to be 125 microseconds for audio data of
frequency 48 kHz.

Fix:
Add slot function support to schedule
the data fetching from the system memory
by the DMA. This will help the AVB SW stack
timing requirements for class A data.

       are redundant. The operations that are done in these
       functions can be included as part of other existing
       OSD-OSI interface API. OSD need not micro-manage the
       hardware controller by using such fine grain APIs.
Fix:   Remove the redundant APIs and implement their functionality
       as part of existing APIs.

6ef38dbc9d nvethernetrm: fix map/unmap of Rx timestamp descriptor 
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.
