By mistake, the of_node of the MDIO device was not setup in the patch
linked below. As a consequence, any PHY driver that depends on the
of_node in its probe callback was not be able to successfully finish its
probe on a PHY, thus the Generic PHY driver was used instead.
Fix this by actually setting up the of_node.

Devices with RMON support has a 16-bit RDRP counter. It provides: "Receive
dropped packets counter. Increments for frames received which are streamed
to system but are later dropped due to lack of system resources."
To handle more than 2^16 dropped packets, a carry bit in CAR1 register is
set on overflow, so we enable irq when this is set, extending the counter
to 2^64 for handling situations where lots of packets are missed (e.g.
during heavy network storms).

The memset on CAMx is wrong, as it actually unmasks all carry irq's,

The memset on CARx registers is just pointless, as they are W1C.
So let's just stop the memset before CAR1.

The nft flow will be destroyed after offload cb returns. This means
we need save a full copy of it since it can be referenced through
other paths other than just the offload cb, for example when a new
pre_ct or post_ct entry is added, and it needs to be merged with
an existing nft entry.

Implement code to add and remove nft flows to the relevant list.
Registering and deregistering the callback function for the nft
table is quite complicated. The safest is to delete the callback
on the removal of the last pre_ct flow. This is because if this
is also the latest pre_ct flow in software it means that this
specific nft table will be freed, so there will not be a later
opportunity to do this. Another place where it looks possible
to delete the callback is when the last nft_flow is deleted,
but this happens under the flow_table lock, which is also taken
when deregistering the callback, leading to a deadlock situation.
This means the final solution here is to delete the callback
when removing the last pre_ct flow, and then clean up any
remaining nft_flow entries which may still be present, since
there will never be a callback now to do this, leaving them
orphaned if not cleaned up here as well.

Add register/unregister of the nft callback. For now just add
stub code to accept the flows, but don't do anything with it.
Decided to accept the flows since netfilter will keep on trying
to offload a flow if it was rejected, which is quite noisy.
Follow-up patches will start implementing the functions to add
nft flows to the relevant tables.

Flows will still not actually be offloaded to hw, but at this point
it's difficult to not accept the flows and also exercise the cleanup
paths properly. Traffic will still be handled safely through the
fallback path.
