[Bug]: Netlink library only parses the first `RTM_NEWLINK` message in a getLink() response.

[jglogan]

I have done the following

• I have searched the existing issues
• If possible, I've reproduced the issue using the 'main' branch of this project

Steps to reproduce

When linkGet() receives the data buffer from the netlink socket, it calls parseResponse() to create a list of LinkResponse objects, each of which has an interfaceIndex and a list of attributes.

The problem is that the parse function is only looking for a single message, instead of processing messages until all data is consumed.

Current behavior

For linkGet(interface: nil) get one RTM_NEWLINK for the first interface, and the data for the remaining interfaces looks like a large final attribute with type 0. Only a single LinkResult is returned.

Expected behavior

The linkGet(interface: nil) call should return a LinkResult for each interface.

Environment

- OS: 26
- Xcode: 26
- Swift: 6.2
