Songmin Li d61e7e5e1f fix(dhcp): can not renew an ip address
The dhcp server is systemd-networkd, and the dhcp
plugin can request an ip but can not renew it.
The systemd-networkd just ignore the renew request.

```

Follow the https://datatracker.ietf.org/doc/html/rfc2131#section-4.3.6,
following options must not be sent in renew

- Requested IP Address
- Server Identifier

Since the upstream code has been inactive for 6 years,
we should switch to another dhcpv4 library.
The new selected one is https://github.com/insomniacslk/dhcp.

CHANGELOG

v1.1.2

  • [Improvement]: updated dependencies, test with Go 1.20.

v1.1.1

  • [Bug Fix]: fix test compilation on big endian machines.

v1.1.0

This is the first release of package packet that only supports Go 1.18+. Users on older versions of Go must use v1.0.0.

  • [Improvement]: drop support for older versions of Go so we can begin using modern versions of x/sys and other dependencies.

v1.0.0

This is the last release of package vsock that supports Go 1.17 and below.

  • Initial stable commit! The API is mostly a direct translation of the previous github.com/mdlayher/raw package APIs, with some updates to make everything focused explicitly on Linux and AF_PACKET sockets. Functionally, the two packages are equivalent, and *raw.Conn is now backed by *packet.Conn in the latest version of the raw package.
