This patch prepares infrastructure for matching sockets by cgroups.
Two helper functions are added for transformation between cgroup v2 ID
and pathname. Cgroup v2 cache is implemented as hash table indexed by ID.
This cache is needed for faster lookups of socket cgroup.

Introduce a ingress frame gate control flow action.
Tc gate action does the work like this:
Assume there is a gate allow specified ingress frames can pass at
specific time slot, and also drop at specific time slot. Tc filter
chooses the ingress frames, and tc gate action would specify what slot
does these frames can be passed to device and what time slot would be
dropped.
Tc gate action would provide an entry list to tell how much time gate
keep open and how much time gate keep state close. Gate action also
assign a start time to tell when the entry list start. Then driver would
repeat the gate entry list cyclically.
For the software simulation, gate action require the user assign a time
clock type.
Below is the setting example in user space. Tc filter a stream source ip
address is 192.168.0.20 and gate action own two time slots. One is last
200ms gate open let frame pass another is last 100ms gate close let
frames dropped.
# tc qdisc add dev eth0 ingress
# tc filter add dev eth0 parent ffff: protocol ip \
flower src_ip 192.168.0.20 \
action gate index 2 clockid CLOCK_TAI \
sched-entry open 200000000ns -1 8000000b \
sched-entry close 100000000ns
# tc chain del dev eth0 ingress chain 0
"sched-entry" follow the name taprio style. Gate state is
"open"/"close". Follow the period nanosecond. Then next -1 is internal
priority value means which ingress queue should put to. "-1" means
wildcard. The last value optional specifies the maximum number of
MSDU octets that are permitted to pass the gate during the specified
time interval, the overlimit frames would be dropped.
Below example shows filtering a stream with destination mac address is
10:00:80:00:00:00 and ip type is ICMP, follow the action gate. The gate
action would run with one close time slot which means always keep close.
The time cycle is total 200000000ns. The base-time would calculate by:
1357000000000 + (N + 1) * cycletime
When the total value is the future time, it will be the start time.
The cycletime here would be 200000000ns for this case.

flower skip_hw ip_proto icmp dst_mac 10:00:80:00:00:00 \

Consider this configuration:

ip link set dev vx0 master br0
bridge vlan del vid 1 dev vx0
ip link add vx1 type vxlan dstport 4790 external

vx1 1 PVID Egress Untagged
root@vsid:/src/iproute2#
Note the useless and inconsistent empty lines.
root@vsid:/src/iproute2# ./bridge/bridge vlan tunnelshow
port vlan-id tunnel-id
br0
vx0 None
vx1
What's the difference between "None" and ""?
root@vsid:/src/iproute2# ./bridge/bridge -j -p vlan tunnelshow
[ {
"ifname": "br0",
"tunnels": [ ]
},{
"ifname": "vx1",
"tunnels": [ ]
} ]
Why does vx0 appear in normal output and not json output?
Why output an empty list for br0 and vx1?
Fix these inconsistencies and avoid outputting entries with no values. This
makes the behavior consistent with other iproute2 commands, for example
`ip -6 addr`: if an interface doesn't have any ipv6 addresses, it is not
part of the listing.

====================
From: Mark Starovoytov <mstarovoitov@marvell.com>
This series adds support for selecting the offloading mode of a MACsec
interface at link creation time.
Available modes are for now 'off', 'phy' and 'mac', 'off' being the default
when an interface is created.
First patch adds support for MAC offloading.
Last patch allows a user to change the offloading mode at runtime
through a new attribute, `ip link add link ... offload`:
# ip link add link enp1s0 type macsec encrypt on offload off
# ip link add link enp1s0 type macsec encrypt on offload phy
# ip link add link enp1s0 type macsec encrypt on offload mac

This patch adds support for configuring offload mode upon MACsec
device creation.
If offload mode is not specified, then netlink attribute is not
added. Default behavior on the kernel side in this case is
backward-compatible (offloading is disabled by default).
Example:
$ ip link add link eth0 macsec0 type macsec port 11 encrypt on offload mac

This patch enables MAC HW offload usage in iproute, since MACSec
implementation supports it now.

Prepare for adding new variable substitutions. Unify the sed rules while

The fq_codel class stat deficit is a signed int. This is a regression

Load memlimit so that it will be printed if it isn't set to zero.
Also add a space to properly print it.
