drivers: wifi: infineon: add .iface_status method

[drensber]

The .iface_status method of the wifi_mgmt_ops API needs to be added so that the "wifi status" command on the network shell will work.

Minor nits about the coding style, you could see what the rest of the airoc_wifi.c looks like and follow suit.

I changed all of these things according to your preferences. Looking at the Zephyr Coding Guidelines, I'm not sure that any of them are actually established rules, so perhaps that's why the automated checks didn't catch any of them.

I think the twister failure is a problem on your side, not a problem with the code that I pushed. Can someone look into this and re-run the tests?

Looked like some environmental issue, I've retriggered failed stage, tests are now running.

Pull Request Overview

This PR adds an .iface_status method to the Infineon WiFi driver so that the "wifi status" command on the network shell works as expected.

• Added the implementation of airoc_iface_status to report interface mode, state, SSID, channel, and other connection parameters.
• Updated the wifi_mgmt_ops structure to include the new .iface_status method.
• Introduced an additional header include for whd_wlioctl.h required by the new functionality.

• The variable 'airoc_if' is referenced without a visible declaration in this diff. Verify that it is properly declared and initialized in an accessible scope before use.

if (airoc_if == NULL) {

[Copilot]

Using strncpy without explicitly appending a null terminator risks leaving status->ssid unterminated. Consider ensuring the string is null-terminated (and that the destination buffer is large enough) after copying.

Suggested change

	strncpy(status->ssid, bss_info.SSID, bss_info.SSID_len);
	if (status->ssid_len < sizeof(status->ssid)) {
	strncpy(status->ssid, bss_info.SSID, status->ssid_len);
	status->ssid[status->ssid_len] = '\0'; // Ensure null-termination
	} else {
	LOG_ERR("SSID length exceeds buffer size");
	return -EINVAL; // Return an error if the buffer is too small
	}

I think Copilot's advice is invalid in this particular case. The SSID is defined by zephyr to be a character string with a max length of 32 and an accompanying SSID_len field to specify the actual length. If I were to use one character of the ssid field as a null terminator, the maximum length would become 31.
