Commit db1a63aed89c ("net: phy: Remove fallback to old C45 method")
removes a fallback C45 method in the MDIO bus driver. This breaks
nvethernet support for Linux v6.3 and the following errors are observed.
failed to register MDIO bus (nvethernet_mdio_bus)
net eth0: failed to register MDIO bus
Fix this by adding the necessary read/write_c45 callbacks in the
nvethernet driver. Note these callbacks are only supported for Linux
v6.3+ kernels.

When mttcan
- is set into DAR (Disable Automatic Retransmission) mode
- and Protocol Exception Handling is enabled
- and PXE (Protocol Exeception Event) is generated
then no TCF (Transmission cancellation Finished) event is generated.
This leads to mismatch between internal driver state and mttcan HW
state. This results in "no buffer space available" error.
This patch clears the driver internal state in close callback to
handle this situation.

The nvethernet driver has a dependency on the NVPPS driver which in
turn has a dependency on the GTE driver. The GTE driver is being
transitioned to the new upstream HTE driver and while this transition is
on-going, allow the nvethernet driver to be distributed and built
without NVPPS and GTE.
Note that by default the dependency on the NVPPS driver is enabled by
setting CONFIG_TEGRA_NVPPS to 'y'. Only if the user sets
CONFIG_TEGRA_NVPPS to 'n' will it be disabled.

Issue: skb_vlan_tag_get gives only the VLAN_ID for
the earlier kernel versions (K4.9) and hence added
a logic to take care of adding the VLAN priority

already included
Fix: remove the logic of explicit adding of VLAN

Issue:
During eth0 down case, the link change gets called twice,
1. due to ndo close
2. due to interrupt generated by phy.
The ether_adjust_link callback also configures the EEE settings
and calls phy_init_eee (a phy framework API) for the same.
Here a race condition occur, when ether_close sets phydev to NULL
before the phy_init_eee gets called (from ether_conf_eee) which tries
to deference the phydev causing kernel panic.

Fix: Update bypass LUT such that if the frames from the VF(on which

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.

2. Remove explicit command from supplicant to set control port and
set protected frames. Handle the same in osi_macsec_init

The functions eth_hw_addr_set() and dev_addr_mod() do not exist for
Linux v5.14 and so compiling the marvell oak driver fails for Linux
v5.14. Fix this by calling memcpy() instead of eth_hw_addr_set() and
dev_addr_mod() for Linux v5.14. Note that both eth_hw_addr_set() and
dev_addr_mod() internally call memcpy() and so this is equivalent.
