Even when we use shortened, combined words, we still should uppercase
where a new word starts. I couldn't find a canonically capitalized
version of this term, hence I think we should follow our naming rules
here.
Old name was slightly misleading, because this flag does not determine
whether DSCP is used overall, but only if it is copied to the
decapsulated packet. Rename to better reflect that.
"Copy" does not imply direction. This is on purpose, because we might
later on enhance the setting to allow/disallow copying in the other
direction, to the encapsulated packet. If that is implemented,
CopyDSCP could understand additional values. This is nicer than
having two separate settings and follows the example of DHCP=.
Also, we try to avoid abbreviations, but we allow acronyms
like MTU, in DiscoverPathMTU=.
This setting was recently added, so it's fine to rename it without
backwards compat.
This patch adds support to configure IFF_VNET_HDR flag
for a tap device. It allows whether sending and receiving
large pass larger (GSO) packets. This greatly increases the
achievable throughput.
Add UDPCheckSum option to enable transmitting UDP checksums when doing
VXLAN/IPv4. Add UDP6ZeroChecksumRx, and UDP6ZeroChecksumTx
options to enable sending zero checksums and receiving zero
checksums in VXLAN/IPv6

The following bond options are supported by this patch.
MIIMonitorSec:
Specifies the frequency in milli-seconds that MII link
monitoring will occur.
UpDelaySec:
Specifies the delay time in milli-seconds to enable a link
after a link up status has been detected.
DownDelaySec:
Specifies the delay time in milli-seconds to disable a link
after a link failure has been detected.

slow : Request partner to transmit LACPDUs every 30 seconds
fast : Request partner to transmit LACPDUs every 1 second
The default is slow.

This patch adds supports networkd to configure bond mode
during creation via persistent conf. Mode can be configured
with conf param 'Mode'. A new section Bond is added to the
conf to support bond mode.
These modes can be configured now.

This patch introduces TUN/TAP device creation support
to networkd.
Example conf to create a tap device:
file: tap.netdev
------------------
[NetDev]
Name=tap-test
Kind=tap
[Tap]
OneQueue=true
MultiQueue=true
PacketInfo=true
User=sus
Group=sus
------------------
Test:
1. output of ip link
tap-test: tap pi one_queue UNKNOWN_FLAGS:900 user 1000 group 1000
id:
uid=1000(sus) gid=10(wheel) groups=10(wheel),1000(sus)
context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
Modifications:
Added:
1. file networkd-tuntap.c
3. netdev kind NETDEV_KIND_TUN and NETDEV_KIND_TAP
2. Tun and Tap Sections and config params to parse
conf and gperf conf parameters
[tomegun: tweak the 'kind' checking for received ifindex]
It may sometimes be necessary to specify the MAC address of a netdev.
Let us set the correct one from the get-go, rather than having the
kernel generate a random one, and then change it after.
This patch adds path of mtu discovery for sit tunnel.
To enable/disable DiscoverPathMTU is introduced.
Example configuration
file: sit.netdev
[NetDev]
Name=sit-tun
Kind=sit
MTUBytes=1480
[Tunnel]
DiscoverPathMTU=1
Local=X.X.X.X
Remote=X.X.X.X
By default pmtudisc is turned on , if DiscoverPathMTU
is missing from the config. To turn it off
DiscoverPathMTU=0 needs to be set.
This does not belong in shared as it is mostly a detail of our networking subsystem.
Moreover, now we can use libudev here, which will simplify things.
