The headers are provided by the MEI driver, but the defines are never
set by the vdsl app. While the struct with the
MEI_SUPPORT_OPTIMIZED_FW_DL conditional isn't used by the vdsl app,
however CMV_USED_PAYLOAD_8BIT_SIZE which value depends on
MEI_SUPPORT_DEBUG_STREAMS is.
Since the MEI driver doesn't provide an autogenerated header with
compile flags, the flags are hardcoded for the vdsl app.
Set them for the MEI driver as well, to indicate a relation to the
values used for the vdsl app and to be not surprised by a changed
default in case the MEI driver gets updated. Use the current default
values defined in the MEI driver.

By setting 'auto', the zero address or the empty string as source
address (option ipaddr, option ip6addr), vxlan will choose one
dynamically. This helps in setups where a wan ip or prefix changes.
This corresponse to setting up an vxlan tunnel with:
proto vxlan6:
# ip link add vx0 type vxlan id ID local :: ...
proto vxlan:
# ip link add vx0 type vxlan id ID local 0.0.0.0 ...
While it is possible to not specify a source ip at all, the kernel will
default to setting up a ipv4 tunnel. The kernel will take any hint from
source and peer ips to figure out, what tunnel type to use. To make sure
we setup an ipv6 tunnel for proto vxlan6, this workaround is needed.
This will not change the behaviour of currently working configurations.
However this will allow former broken configurations, namely those not
specifying both a source address and tunnel interface, to setup a
tunnel interface. Previously those configurations weren't reporting an
error and were stueck in a setup loop like in Bug FS#3426.
This change lifts the currently very strict behaviour and should fix the
following bug:

This package provides the necessary files to translate `config dsa_vlan`
and `config dsa_port` sections of `/etc/config/network` into appropriate
bridge vlan filter rules.
The approach of the configuration is to bridge all DSA ports into a logical
bridge device, called "switch0" by default, and to set VLAN port membership,
tagging state and PVID as specified by UCI on each port and on the switch
bridge device itself, allowing logical interfaces to reference port VLAN
groups by using "switch0.N" as ifname, where N denotes the VLAN ID.

Similar to wireguard, vxlan can configure multiple peers or add specific
entries to the fdb for a single mac address.
While you can still use peeraddr/peer6addr option within the proto
vxlan/vxlan6 section to not break existing configurations, this patch
allows to add multiple sections that conigure fdb entries via the bridge
command. As such, the bridge command is now a dependency of the vxlan
package. (To be honest without the bridge command available, vxlan isn't
very much fun to use or debug at all)
Field names are taken direclty from the bridge command.
Example with all supported parameters, since this hasn't been documented so
far:
config interface 'vx0'
option proto 'vxlan6' # use vxlan over ipv6
# main options
option ip6addr '2001:db8::1' # listen address
option tunlink 'wan6' # optional if listen address given
option peer6addr '2001:db8::2' # now optional
option port '8472' # this is the standard port under linux
option vid '42' # VXLAN Network Identifier to use
option mtu '1430' # vxlan6 has 70 bytes overhead
# extra options
option rxcsum '0' # allow receiving packets without checksum
option txcsum '0' # send packets without checksum
option ttl '16' # specifies the TTL value for outgoing packets
option tos '0' # specifies the TOS value for outgoing packets
option macaddr '11:22:33:44:55:66' # optional, manually specify mac
# default is a random address
Single peer with head-end replication. Corresponds to the following call
to bridge:
$ bridge fdb append 00:00:00:00:00:00 dev vx0 dst 2001:db8::3
config vxlan_peer
option vxlan 'vx0'
option dst '2001:db8::3' # always required
For multiple peers, this section can be repeated for each dst address.
It's possible to specify a multicast address as destination. Useful when
multicast routing is available or within one lan segment:
config vxlan_peer
option vxlan 'vx0'
option dst 'ff02::1337' # multicast group to join.
# all bum traffic will be send there
option via 'eth1' # for multicast, an outgoing interface needs
# to be specified
All available peer options for completeness:
config vxlan_peer
option vxlan 'vx0' # the interface to configure
option lladdr 'aa:bb:cc:dd:ee:ff' # specific mac,
option dst '2001:db8::4' # connected to this peer
option via 'eth0.1' # use this interface only
option port '4789' # use different port for this peer
option vni '23' # override vni for this peer
option src_vni '123' # see man 3 bridge

In the package guidelines, PKG_VERSION is supposed to be used as
"The upstream version number that we're downloading", while
PKG_RELEASE is referred to as "The version of this package Makefile".
Thus, the variables in a strict interpretation provide a clear
distinction between "their" (upstream) version in PKG_VERSION and
"our" (local OpenWrt trunk) version in PKG_RELEASE.
For local (OpenWrt-only) packages, this implies that those will only
need PKG_RELEASE defined, while PKG_VERSION does not apply following
a strict interpretation. While the majority of "our" packages actually
follow that scheme, there are also some that mix both variables or
have one of them defined but keep them at "1".
This is misleading and confusing, which can be observed by the fact
that there typically either one of the variables is never bumped or
the choice of the variable to increase depends on the person doing the
change.
Consequently, this patch aims at clarifying the situation by
consistently using only PKG_RELEASE for "our" packages. To achieve
that, PKG_VERSION is removed there, bumping PKG_RELEASE where
necessary to ensure the resulting package version string is bigger
than before.
During adjustment, one has to make sure that the new resulting composite
package version will not be considered "older" than the previous one.
A useful tool for evaluating that is 'opkg compare-versions'. In
principle, there are the following cases:
1. Sole PKG_VERSION replaced by sole PKG_RELEASE:
In this case, the resulting version string does not change, it's
just the value of the variable put in the file. Consequently, we
do not bump the number in these cases so nobody is tempted to
install the same package again.
2. PKG_VERSION and PKG_RELEASE replaced by sole PKG_RELEASE:
In this case, the resulting version string has been "version-release",
e.g. 1-3 or 1.0-3. For this case, the new PKG_RELEASE will just
need to be higher than the previous PKG_VERSION.
For the cases where PKG_VERSION has always sticked to "1", and
PKG_RELEASE has been incremented, we take the most recent value of
PKG_RELEASE.
Apart from that, a few packages appear to have developed their own
complex versioning scheme, e.g. using x.y.z number for PKG_VERSION
_and_ a PKG_RELEASE (qos-scripts) or using dates for PKG_VERSION
(adb-enablemodem, wwan). I didn't touch these few in this patch.

cases, so there is no harm done for version comparison.)

Running your firewall's "wan" zone in REJECT zone (1) exposes the
presence of the router, (2) depending on the sophistication of
fingerprinting tools might identify the OS and release running on
the firewall which then identifies known vulnerabilities with it
and (3) perhaps most importantly of all, your firewall can be
used in a DDoS reflection attack with spoofed traffic generating
ICMP Unreachables or TCP RST's to overwhelm a victim or saturate
his link.
This rule, when enabled, allows traceroute to work even when the
default input policy of the firewall for the wan zone has been

The current implementation is significantly lowering lantiq
performace [1][2] by using RPS with non-irq CPUs and XPS
with alternating CPUs.
The previous netifd implementation (by default but could be
configured) simply used all CPUs and this patch essentially
reverts to this behaviour.
The only document suggesting using non-interrupt CPUs is Red
Hat [3] where if the network interrupt rate is extremely high
excluding the CPU that handles network interrupts *may* also
improve performance.
The original packet steering patches [4] advise that optimal
settings for the CPU mask seems to depend on architectures
and cache hierarcy so one size does not fit all. It also
advises that the overhead in processing for a lightly loaded
server can cause performance degradation.
Ideally, proper IRQ balancing is a better option with
the irqbalance daemon or manually.
The kernel does not enable packet steering by default, so
also disable in OpenWRT by default. (Though mvebu with its
hardware scheduling issues [5] might want to enable packet
steering by default.)
Change undocumented "default_ps" parameter to clearer
"packet_steering" parameter. The old parameter was only ever
set in target/linux/mediatek/base-files/etc/uci-defaults/99-net-ps
and matched the default.
