When marking a switch port as disabled in the device tree, by using
'status = "disabled";', the switch driver fails on boot, causing a
restart:
CPU 0 Unable to handle kernel paging request at virtual address
00000000, epc == 802c3064, ra == 8022b4b4
[ ... ]
Call Trace:
[<802c3064>] strlen+0x0/0x2c
[<8022b4b4>] start_creating.part.0+0x78/0x194
[<8022bd3c>] debugfs_create_dir+0x44/0x1c0
[<80396dfc>] rtl838x_dbgfs_port_init+0x54/0x258
[<80397508>] rtl838x_dbgfs_init+0xe0/0x56c
This is caused by the DSA subsystem (mostly) ignoring the port, while
rtl83xx_mdio_probe() still extracts some details on this disabled port
from the device tree, resulting in the usage of a NULL pointer where a
port name is expected.
By not probing ignoring disabled ports, no attempt is made to create a
debugfs directory later. The device then boots as expected without the
disabled port.

Setting up DSA bond silently fails if mode is not 802.3ad. Add log message
to fix it. As we are already here harmonize all logging messages in the
add/delete functions.

Instead of directly calling SoC-specific functions in order to access
(paged) MII registers or MMD registers, create infrastructure to allow
using the generic phy_*, phy_*_paged and phy_*_mmd functions.

Using the led-set attribute of a port in the dts we allow configuration
of the port leds. Each led-set is being defined in the led-set configuration
of the .dts, giving a specific configuration to steer the port LEDs via a serial
connection.

We were using the PHY-ids (the reg entries in the PHY
sections of the .dts) as the port numbers. Now scan the
ports section in the .dts, and use the actual port numbers,
following the phy-handle to the PHY properties.

Commit 03e1d93e0779 ("realtek: add driver support for routing
offload") added routing offload for IPv4, but broke IPv6 routing
completely. The routing table is empty and cannot be updated:
root@gs1900-10hp:~# ip -6 route
root@gs1900-10hp:~# ip -6 route add unreachable default
RTNETLINK answers: Invalid argument
As a side effect, this breaks opkg on IPv4 only systems too,
since uclient-fetch fails when there are no IPv6 routes:
root@gs1900-10hp:~# uclient-fetch http://192.168.99.1
Downloading 'http://192.168.99.1'
Failed to send request: Operation not permitted
Fix by returning NOTIFY_DONE when offloading is unsupported, falling
back to default behaviour.

Add generic support for listening to FIB and Event notifier updates and
use this information to hook into the L3 hardware capabilities of the
RTL SoCs.

This adds support for offloading TC flower by using the Packet Inspection Engine
of the RTL-SoCs. Basic infrastructure support is provide with callbacks to the

dsa_to_port function in 5.10 returns dsa_port from the port list in
dsa_switch_tree, but the tree is built when the switch is registered
by dsa_register_switch and it's null in rtl83xx_mdio_probe.
So, we need to use dsa_to_port after the registration of the switch.

this patch fixes the following errors when compiling:
- dsa_switch_alloc is removed[1]
- a parameter "enum dsa_tag_protocol mprot" is added to dsa_tag_protocol
in dsa_switch_ops (include/net/dsa.h)
- several paramters are added to "phylink_mac_link_up" in dsa_switch_ops
(include/net/dsa.h)
added:
- int speed
- int duplex
- bool tx_pause
- bool rx_pause
- a parameter "struct switchdev_trans *trans" is added to
port_vlan_filtering in dsa_switch_ops (include/net/dsa.h)
