drivers/net/ethernet/smsc/smc911x.c:483:17: note: in expansion of macro ‘min’

Fix this by making the constant unsigned, to match the type of "len".
While at it, replace the other missed ternary operator by min(), too.
Convert the dummy PRINT_PKT() from a macro to a static inline function,
to catch mistakes like this without having to enable debug options
manually.

The last caller of the stmmac_desc_ops::get_addr() callback was removed

Note that the callback also only gets half the descriptor address on

The port_cnt value in the structure is not used in the switch_init.
Instead it uses the fls(chip->cpu_port), this is due to one of port in
the ksz8794 unavailable. The cpu_port for the 8794 is 0x10, fls(0x10) =

Multiport eswitch mode is a LAG mode that allows to add rules that
forward traffic to a specific physical port without being affected by LAG
affinity configuration.
This mode of operation is mutual exclusive with the other LAG modes used
by multipath and bonding.
To make the transition between the modes, we maintain a counter on the
number of rules specifying one of the uplink representors as the target
of mirred egress redirect action.
An example of such rule would be:
$ tc filter add dev enp8s0f0_0 prot all root flower dst_mac \
00:11:22:33:44:55 action mirred egress redirect dev enp8s0f0
If the reference count just grows to one and LAG is not in use, we
create the LAG in multiport eswitch mode. Other mode changes are not
allowed while in this mode. When the reference count reaches zero, we
destroy the LAG and let other modes be used if needed.
logic also changed such that if forwarding to some uplink destination
cannot be guaranteed, we fail the operation so the rule will eventually
be in software and not in hardware.

LAG state machine is implemented using bit flags. However, all these bit
flags, except for MLX5_LAG_FLAG_HASH_BASED, are really mutual exclusive.
In addition, MLX5_LAG_FLAG_READY is used by bonding to mark if we have
our netdevices successfully added to lag and does not really belong in
the same flags variable as the other flags.
Rename MLX5_LAG_FLAG_READY to MLX5_LAG_FLAG_NDEVS_READY to better
reflect its purpose and put it in a new flags variable.
For the rest of the flags, we introduce a mode enum to hold the state
of the LAG.
Remove the shared fdb boolean flag from struct mlx5_lag and store this
configuration as a mode flag.
Change all flag related operations to use standard Linux APIs.
