bba351803a nvethernet:Update CAR programming for MACSec
Issue: 1. Not able to launch supplicant on second VF
2. When launching supplicant on VF1, MACSec link on VF0 is getting lost

Fix: Do not program CAR registers as part of OSD as the same is being
taken care by Server and also do not register for MACSec interrupts.
Same is being handled in Server
2. Enabled packet duplication for MultiCast frames when launching
supplicant

8fc898d1ec nvethernet: assign macsec private data to NULL
Issue:
L4T platforms on boot comes up with MTU as 1500.
However on changing the MTU to jumbo, the final
MTU which gets set accounts the MACSEC ICV tag
len and reduces the MTU by 34 bytes even though
the platform does not support MACSEC.

Fix:
Assign macsec allocated private data to NULL and
use the NULL check in ndo mtu change ioctl call
to reject MTU reduction if macsec is not supported.

306f33d38e nvethernet: Read instance_id irrespective of macsec.
Issue:
MGBE0 ASID is getting programmed for all the MAC instances
which inturn causing the data transfer failures.Macsec is not enable
and hence instance_id is not getting updated to the corresponding mac
instance number and hence all mac instance_id's are initialized with 0.
Since ASID programming is based on mac instance_id, all MACs are
programmed with MGBE0 MAC instance id.

Fix:
Moved reading of instance_id from DT out of macsec_probe and hence the
instance_id gets updated irrespective of MAC sec enable/disable.

d07b3d604c nvethernet:MACSEC, add byp lut with VF MAC
Issue: If the supplicant is killed for some reason Data would flow
plain on that interface, this needs to be avoided

Fix: Update bypass LUT such that if the frames from the VF(on which
supplicant is launched) is received on MACSEC either authenticate the
same or drop. Along with this handles below items as well. All the VFs MACIDs
are obtained in OSI to update the bypass LUTs to decide on which VF frames
to be authenticated and which VF frames needs to be bypassed.

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

supplicant running, if there is any supplicant then enable the macsec
post resume.
