In order to calculate the idleSlope parameter of CBS correctly, users
must take into account the entire packet size, including the overhead
from all layers.
Add some more details to the man page to clarify that, giving one
simple example and pointing users to the correct 802.1Q section for
further clarifications if needed.

IP6_TNL_F_ALLOW_LOCAL_REMOTE allows tunnel traffic on ip6tnl devices
where the remote endpoint is a local host address.
Specifying "[no]allow-localremote" controls the
IP6_TNL_F_ALLOW_LOCAL_REMOTE flag on ip6tnl interfaces.
This is the user-space counterpart for kernel

This patch adds the iproute2 support for getting and setting the

the raw value.
The man page is also updated with the new option.

The AF_VSOCK address family is a host<->guest communications channel
supported by VMware, KVM, and Hyper-V. Initial VMware support was
released in Linux 3.9 in 2013 and transports for other hypervisors were
added later.
AF_VSOCK addresses are <u32 cid, u32 port> tuples. The 32-bit cid
integer is comparable to an IP address. AF_VSOCK ports work like
TCP/UDP ports.
Both SOCK_STREAM and SOCK_DGRAM socket types are available.
This patch adds AF_VSOCK support to ss(8) so that sockets can be
observed.

This patch adds support to the iproute2 tc filter command for matching MPLS

the flower filter.

The patch adds ERSPAN type II tunnel support. The implementation is
based on the draft at
https://tools.ietf.org/html/draft-foschiano-erspan-01.
One of the purposes is for Linux box to be able to receive ERSPAN
monitoring traffic sent from the Cisco switch, by creating a ERSPAN
tunnel device. In addition, the patch also adds ERSPAN TX, so traffic
can also be encapsulated into ERSPAN and sent out.
The implementation reuses the key as ERSPAN session ID, and
field 'erspan' as ERSPAN Index fields:
./ip link add dev ers11 type erspan seq key 100 erspan 123 \
local 172.16.1.200 remote 172.16.1.100

In the presence of firewalls which improperly block ICMP Unreachable
(including Fragmentation Required) messages, Path MTU Discovery is
prevented from working.
The workaround is to handle IPv4 payloads opaquely, ignoring the DF
bit.
Kernel commit 22a59be8b7693eb2d0897a9638f5991f2f8e4ddd ("net: ipv4:
Add ability to have GRE ignore DF bit in IPv4 payloads") is
complemented by this user-space changeset which exposes control of
this setting.
