This patch adds support for tc flower hardware offload on the ingress
path. Shared filter blocks are supported by sharing a single ACL table
between multiple ports.
The following flow keys are supported:
- Ethernet: dst_mac/src_mac
- IPv4: dst_ip/src_ip/ip_proto/tos
- VLAN: vlan_id/vlan_prio/vlan_tpid/vlan_dei
- L4: dst_port/src_port
As per flow actions, the following are supported:
- drop
- mirred egress redirect
- trap
Each ACL entry (filter) can be setup with only one of the listed
actions.
A sorted single linked list is used to keep the ACL entries by their
order of priority. When adding a new filter, this enables us to quickly
ascertain if the new entry has the highest priority of the entire block
or if we should make some space in the ACL table by increasing the
priority of the filters already in the table.

Add an ACL entry in each port's ACL table to redirect any frame that
has the destination MAC address equal to the STP dmac to the control
interface.

In order to trap frames to the CPU, the DPAA2 switch uses the ACL table.
At probe time, create an ACL table for each switch port so that in the
next patches we can use this to trap STP frames and redirect them to the
control interface.

Add support for configuring the learning state of a switch port.
When the user requests the HW learning to be disabled, a fast-age
procedure on that specific port is run so that previously learnt
addresses do not linger.
At device probe as well as on a bridge leave action, the ports are
configured with HW learning disabled since they are basically a
standalone port.
At the same time, at bridge join we inherit the bridge port BR_LEARNING
flag state and configure it on the switch port.
There were already some MC firmware ABI functions for changing the
learning state, but those were per FDB (bridging domain) and not per
port so we need to adjust those to use the new MC fw command which is
per port.

Multiple ABI function declarations are split unnecessarry on multiple
lines. Fix this so that we have a consistent coding style.

The maximum number of DPAA2 switch interfaces, including the control
interface, is 64. Even though this restriction existed from the first
place, the command structures which use an interface id bitmap were
poorly described and even though a single uint64_t is enough, all of
them used an array of 4 uint64_t's.
Fix this by reducing the size of the interface id field to a single
uint64_t.

Running kernel-doc over the dpaa2-switch driver generates a bunch of
warnings. Fix them up by removing code comments for macros which are
self-explanatory and adding a bit more context for the
dpsw_if_get_port_mac_addr() function and the fields of the
dpsw_vlan_if_cfg structure.

Now that the dpaa2-switch driver has basic I/O capabilities on the
switch port net_devices and multiple bridging domains are supported,
move the driver out of staging.
The dpaa2-switch driver is placed right next to the dpaa2-eth driver
since, in the near future, they will be sharing most of the data path.
I didn't implement code reuse in this patch series because I wanted to
keep it as small as possible.
Also, the README is removed from staging with the intention to add
proper rst documentation afterwards to actually match was is supported
by the driver.
