Refactor and assign one wiphy to each interface #24

Closed rickywu0421 closed 2 years ago

rickywu0421 commented 2 years ago

I renamed the owl_ndev_priv_context to owl_vif in order to reveal the structure includes all the fields which are interface-dependent.

I also moved many fields in owl_context to owl_vif to keep owl_context interface-independent.

In order to add a virtual interface to a network namespace for testing, every virtual interface is assigned to a specific wiphy.

For the future support for more than two interfaces, I rewrote some code in ndo_start_xmit to fit more general circumstances.

User now can pass the module parameter "interfaces" to vwifi, and thus the driver will generate desired number of interfaces, which are all in STA mode. For the future support for different mode, one can implement change_virtual_intf(), and call it through nl80211.

I got an error from the make check.

I got this error message too for unknown reason, which is generated by the following command:

$ sudo iw dev owl0 link
Connected to 26:05:d1:60:34:c8 (on owl0)
    SSID: MyHomeWiFi
    freq: 2437
command failed: No such file or directory (-2)

However, this error message will not affect the whole testing.

Ok, let's open another issue for tracking this error message. I approve of #24
