Retrieve a list of physical network interfaces on the system.
This function checks the `/sys/class/net/` directory to identify physical

the presence of a symbolic link to a `device` directory.

Retrieves a list of virtual network interfaces on the system.
This function scans the network interfaces available in the '/sys/class/net/'

show_all (bool): If True, includes both physical and virtual interfaces

Output:
Prints a table with the following columns:
- Interface: The name of the network interface.
- IP Address: The IP address assigned to the interface.
- Subnet: The subnet mask associated with the IP address.
- MAC Address: The MAC address of the interface.
Notes:
- The function uses the `ip` command to fetch interface details.
- If an interface does not have an IP address, "No IP" is displayed in the
IP Address column.
- If an error occurs while fetching details for an interface, an error
message is printed for that interface.
