When enetc runs out of exact match entries for unicast address
filtering, it switches to an approach based on hash tables, where
multiple MAC addresses might end up in the same bucket.
However, the enetc_set_mac_ht_flt function currently depends on the
system endianness, because it interprets the 64-bit hash value as an
array of two u32 elements. Modify this to use lower_32_bits and
upper_32_bits.
Tested by forcing enetc to go into hash table mode by creating two
macvlan upper interfaces:
ip link add link eno0 address 00:01:02:03:00:00 eno0.0 type macvlan && ip link set eno0.0 up
ip link add link eno0 address 00:01:02:03:00:01 eno0.1 type macvlan && ip link set eno0.1 up
and verified that the same bit values are written to the registers
before and after:
enetc_sync_mac_filters: addr 00:00:80:00:40:10 exact match 0
enetc_sync_mac_filters: addr 00:00:00:00:80:00 exact match 0

ENETC has a 64-entry hash table for VLAN RX filtering per Station
Interface, which is accessed through two 32-bit registers: VHFR0 holding
the low portion, and VHFR1 holding the high portion.
The enetc_set_vlan_ht_filter function looks at the pf->vlan_ht_filter
bitmap, which is fundamentally an unsigned long variable, and casts it
to a u32 array of two elements. It puts the first u32 element into VHFR0
and the second u32 element into VHFR1.
It is easy to imagine that this will not work on big endian systems
(although, yes, we have bigger problems, because currently enetc assumes
that the CPU endianness is equal to the controller endianness, aka
little endian - but let's assume that we could add a cpu_to_le32 in
enetc_wd_reg and a le32_to_cpu in enetc_rd_reg).
Let's use lower_32_bits and upper_32_bits which are designed to work
regardless of endianness.
Tested that both the old and the new method produce the same results:
$ ethtool -K eth1 rx-vlan-filter on
$ ip link add link eth1 name eth1.100 type vlan id 100
enetc_set_vlan_ht_filter: method 1: si_idx 0 VHFR0 0x0 VHFR1 0x20

netfilter: flowtable enhancements
[ This is v2 that includes documentation enhancements, including
existing limitations. This is a rebase on top on net-next. ]
The following patchset augments the Netfilter flowtable fastpath to
support for network topologies that combine IP forwarding, bridge,
classic VLAN devices, bridge VLAN filtering, DSA and PPPoE. This
includes support for the flowtable software and hardware datapaths.
The following pictures provides an example scenario:
fast path!
.------------------------.
/ \
| IP forwarding |
| / \ \/
| br0 wan ..... eth0
. / \ host C
-> veth1 veth2
. switch/router
.
.
eth0
host A
The bridge master device 'br0' has an IP address and a DHCP server is
also assumed to be running to provide connectivity to host A which
reaches the Internet through 'br0' as default gateway. Then, packet
enters the IP forwarding path and Netfilter is used to NAT the packets
before they leave through the wan device.
The general idea is to accelerate forwarding by building a fast path
that takes packets from the ingress path of the bridge port and place
them in the egress path of the wan device (and vice versa). Hence,
skipping the classic bridge and IP stack paths.
** Patch from #1 to #6 add the infrastructure which describes the list of
netdevice hops to reach a given destination MAC address in the local
network topology.
Patch #1 adds dev_fill_forward_path() and .ndo_fill_forward_path() to
netdev_ops.
Patch #2 adds .ndo_fill_forward_path for vlan devices, which provides
the next device hop via vlan->real_dev, the vlan ID and the
protocol.
Patch #3 adds .ndo_fill_forward_path for bridge devices, which allows to make
lookups to the FDB to locate the next device hop (bridge port) in the
forwarding path.
Patch #4 extends bridge .ndo_fill_forward_path to support for bridge VLAN
filtering.
Patch #5 adds .ndo_fill_forward_path for PPPoE devices.
Patch #6 adds .ndo_fill_forward_path for DSA.
Patches from #7 to #14 update the flowtable software datapath:
Patch #7 adds the transmit path type field to the flow tuple. Two transmit
paths are supported so far: the neighbour and the xfrm transmit
paths.
Patch #8 and #9 update the flowtable datapath to use dev_fill_forward_path()
to obtain the real ingress/egress device for the flowtable datapath.
This adds the new ethernet xmit direct path to the flowtable.
Patch #10 adds native flowtable VLAN support (up to 2 VLAN tags) through
dev_fill_forward_path(). The flowtable stores the VLAN id and
protocol in the flow tuple.
Patch #11 adds native flowtable bridge VLAN filter support through
dev_fill_forward_path().
Patch #12 adds native flowtable bridge PPPoE through dev_fill_forward_path().
Patch #13 adds DSA support through dev_fill_forward_path().
Patch #14 extends flowtable selftests to cover for flowtable software
datapath enhancements.
** Patches from #15 to #20 update the flowtable hardware offload datapath:
Patch #15 extends the flowtable hardware offload to support for the
direct ethernet xmit path. This also includes VLAN support.
Patch #16 stores the egress real device in the flow tuple. The software
flowtable datapath uses dev_hard_header() to transmit packets,
hence it might refer to VLAN/DSA/PPPoE software device, not
the real ethernet device.
Patch #17 deals with switchdev PVID hardware offload to skip it on
egress.
Patch #18 adds FLOW_ACTION_PPPOE_PUSH to the flow_offload action API.
Patch #19 extends the flowtable hardware offload to support for PPPoE
Patch #20 adds TC_SETUP_FT support for DSA.
** Patches from #20 to #23: Felix Fietkau adds a new driver which support
hardware offload for the mtk PPE engine through the existing flow
offload API which supports for the flowtable enhancements coming in
this batch.
Patch #24 extends the documentation and describe existing limitations.
Please, apply, thanks.

This patch adds dev_fill_forward_path() which resolves the path to reach
the real netdevice from the IP forwarding side. This function takes as
input the netdevice and the destination hardware address and it walks
down the devices calling .ndo_fill_forward_path() for each device until
the real device is found.
For instance, assuming the following topology:
IP forwarding
/ \
br0 eth0
/ \
eth1 eth2
.
.
.
ethX
ab💿ef🆎cd:ef
where eth1 and eth2 are bridge ports and eth0 provides WAN connectivity.
ethX is the interface in another box which is connected to the eth1
bridge port.
For packets going through IP forwarding to br0 whose destination MAC
address is ab💿ef🆎cd:ef, dev_fill_forward_path() provides the
following path:
br0 -> eth1
.ndo_fill_forward_path for br0 looks up at the FDB for the bridge port
from the destination MAC address to get the bridge port eth1.
This information allows to create a fast path that bypasses the classic
bridge and IP forwarding paths, so packets go directly from the bridge
port eth1 to eth0 (wan interface) and vice versa.

When an MRP instance was created, the driver was notified that the
instance is created and then in a different callback about role of the
instance. But when the instance was deleted the driver was notified only
that the MRP instance is deleted and not also that the role is disabled.
This patch make sure that the driver is notified that the role is
changed to disabled before the MRP instance is deleted to have similar
callbacks with the creating of the instance. In this way it would
simplify the logic in the drivers.

Current calculation for diff of TMR_ADD register value may have
64-bit overflow in this code line, when long type scaled_ppm is
large.
adj *= scaled_ppm;
This patch is to resolve it by using mul_u64_u64_div_u64().

There are some variables in HNS driver will not being referenced
before assigned, so there is no need to init them.
