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.

5faa6bc5bd nvethernetrm: Remove APIs that micro-manage the controller 
Issue: APIs like osi_clear_tx/rx_intr, osi_update_rx_tailptr
       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.

Issue: If the supplicant is killed for some reason Data would flow
plain on that interface, this is not expected

Fix: All the unicast frames from/to the MACSEC interfaceare
authenticated or dropped. Below are the detailes of the changes:

1. Update Rx bypass LUT such that frames on the MACSEC VF(on which
supplicant is launched) would be authenticated or dropped.
2. A dummy SCI LUT is created with the MACSEC VF MACID such
that all the tx frames from MACSEC VF would be sectagged.
3.As part of delete SCI LUT, added the an_valid map as 0 such
that Invalid_SC_AN errors are seen when frames are transmitted
post session termination.

Added below cleanup changes as well to this CL

1. Remove osi_macsec_en API and have single API to init and deinit
2. Remove explicit command from supplicant to set control port and
set protected frames. Handle the same in osi_macsec_init
