2018-05-12wil6210: fix call to wil6210_disconnect during unloadLior David1-4/+4
Move the call to wil6210_disconnect so it will be called before unregister_netdevice. This is because it calls netif_carrier_off which is forbidden to call on an unregistered net device. Calling netif_carrier_off can add a link watch event which might be handled after net device was freed, causing a kernel oops.

Track the connection status per-VIF. The data path code is also updated to support multiple VIFs. This includes RX and TX VRING management, NAPI poll loops, RX reordering and related code.

2018-02-27wil6210: rename p2p_wdev_mutex to vif_mutexLior David5-41/+41
As more support is added for multiple VIFs, there is a need to protect the wil6210_vif structure from access while it is deleted (mainly from del_virtual_intf operation). Instead of adding another mutex, use p2p_wdev_mutex and rename it to vif_mutex to reflect the added role. Its existing roles are similar so it extends nicely (for example it protects the scan_request member which is also a member of wil6210_vif).

2018-02-27wil6210: add support for adding and removing virtual interfacesLior David6-59/+518
Add generic support in cfg80211 operations add_virtual_intf and del_virtual_intf for adding/removing VIFs of any interface type, and fix change_virtual_intf to allow changing the interface type of a VIF. Previously these operations only worked for the P2P_DEVICE interface which is not a real VIF(it is management-only and shares radio with the main interface). Currently the interface combination is validated, the VIF is added/removed in the firmware and the appropriate net/wireless device is also added/removed. Added minimal support for proper interface up/down and module unload but most operations still work only on the main interface.

2018-02-27wil6210: infrastructure for multiple virtual interfacesLior David15-615/+877
Simple infrastructure changes for supporting multiple virtual interfaces (multiple VIFs). It is still not possible to add new VIFs so the only VIF belongs to the main interface. Main changes: 1. Add MAC ID(mid) argument to wmi_send and wmi_call to allow invoking WMI commands on different VIFs. 2. Similarly, in WMI event handler look at the mid reported by FW and extract VIF structure (currently only for main interface). All WMI event handlers operate on wil6210_vif structure so they know on which VIF they were called. 3. Trivial changes to use wil6210_vif structure and MID throughout the code. 4. Various changes to logging to report MID. More complete multiple VIFs support will be added gradually in next patches.

New FW which supports multiple virtual interfaces, reports its allowed interface combinations using a special comment record in the FW file.

For supporting multiple virtual interfaces in the future, introduce a wil6210_vif structure which will hold per-VIF data. Change the module initialization so wil6210_vif will be part of net_device structure, and wireless_dev will be embedded inside the wil6210_vif structure. This will allow us to find the appropriate wil6210_vif structure when we only have access to wireless_dev or net_device.

In order to allow using the same brd file across different 11ad chips, the address for loading the brd file should be part of the FW file, instead of the brd file.

2018-01-25wil6210: fix random failure to bring network interface upLior David5-2/+138
Currently when we want to bring the interface up, we first reset the device which causes the boot loader to run. Then we halt the device CPU, load FW image and resume the device CPU. There are some boot loader versions which perform redundant memory accesses even when idle. Halting the device CPU while boot loader access memory can cause the device memory controller to get stuck, the FW will fail to load and the network interface will not come up. For such boot loaders implement a workaround where we freeze the boot loader before halting the device CPU, so it will not perform any memory accesses.
