bd29dfef8b udev/net: also support [SR-IOV] section in .link files
The same section is already supported by .network files. But such
low-level inteerface setting should be done by udevd, instead of
networkd. Let's also support the same semantics by .link files.

Prompted by https://github.com/systemd/systemd/issues/20474#issuecomment-901901360.

Follow-up for 406041b7de.

Also, this makes
- the settings accept an empty string,
- if the specified value is too large, also use the advertised maximum
  value.
- mention the range of the value in the man page.

udev: Support "max" string for BufferSize options (#20458)
"max" indicates the hardware advertised maximum queue buffer size
should be used.

The max sizes can be checked by running `ethtool -g <dev>` (Preset maximums).
Since the buffer sizes can't be set to 0 by users, internally we use 0 to
indicate that the hardware advertised maximum should be used.

2480ca95ba man: network: use networkctl list instead of status to list network interface type
To determine the network interface type for use in the `Type=` directive, it is more concise to use the `list` command. Whereas, the `status` command requires an interface parameter.

For example, on a RaspberryPi 4 the following shows that the `wlan0` interface type `wlan` is more coveniently listed by the `list` command.

```
root@raspberrypi4-64:~# networkctl list
IDX LINK  TYPE     OPERATIONAL SETUP
  1 lo    loopback carrier     unmanaged
  2 eth0  ether    routable    configured
  3 wlan0 wlan     off         unmanaged

3 links listed.
```

Whereas the `networkctl status` command doesn't include this information.

```
root@raspberrypi4-64:~# networkctl status
●   State: routable
  Address: 192.168.1.141 on eth0
           fd8b:8779:b7a4::f43 on eth0
           fd8b:8779:b7a4:0:dea6:32ff:febe:d1ce on eth0
           fe80::dea6:32ff:febe:d1ce on eth0
  Gateway: 192.168.1.1 (CZ.NIC, z.s.p.o.) on eth0
      DNS: 192.168.1.1

May 07 14:17:18 raspberrypi4-64 systemd-networkd[212]: eth0: Gained carrier
May 07 14:17:19 raspberrypi4-64 systemd-networkd[212]: eth0: Gained IPv6LL
May 07 14:17:19 raspberrypi4-64 systemd-networkd[212]: eth0: DHCPv6 address fd8b:8779:b7a4::f43/128 timeout preferred -1 valid -1
May 07 14:17:21 raspberrypi4-64 systemd-networkd[212]: eth0: DHCPv4 address 192.168.1.141/24 via 192.168.1.1
```

To get the interface type using the `status` command you need to specify an additional argument.

```
root@raspberrypi4-64:~# networkctl status wlan0
● 3: wlan0

1f8dc96c06 udev: rename TxQueueLength= -> TransmitQueueLength=
As we usually (unfortunately not always though) do not use abbreviations.

Tx may be standard abbreviation, but we already have e.g.
TransmitChecksumOffload=. So, let's use Transmit instead of Tx.

ef4a91a7e8 udev: introduce TxQueueLength= setting
Enable udev to set the transmit queue length of a device via a new directive to
be used in link files. The kernel stores this parameter as an unsigned 32 bit
integer. As typical values currently range in the order of 10 to a few 10,000
packets reduce the domain of valid values for this directive to 0..4294967294
and take the excluded 4294967295 == UINT32_MAX to indicate that the directive
is unset.

bdac560801 tree-wide: drop quotes from around [section]
For users, the square brackets already serve as markup and clearly delineate
the section name from surrounding text. Putting additional markup around that
only adds clutter. Also, we were very inconsistent in using the quotes. Let's

0b1e5b6ed8 man: describe naming schemes in a new man page
I decided to make this a separate man page because it is freakin' long.
This content could equally well go in systemd-udevd.service(8), systemd.link(5),
or a new man page for the net_id builtin.

v2:
- rename to systemd.net-naming-scheme
- add udevadm test-builtin net_id example
