* gianfar: Fix stashing supportAndy Fleming2009-02-04
| | | | | | | | | | Stashing is only supported on the 85xx (e500-based) SoCs. The 83xx and 86xx chips don't have a proper cache for this. U-Boot has been updated to add stashing properties to the device tree nodes of gianfar devices on 85xx. So now we modify Linux to keep stashing off unless those properties are there.

* virtio_net: Add support for VLAN filtering in the hypervisorAlex Williamson2009-02-04
| | | | | | | | | | | | VLAN filtering allows the hypervisor to drop packets from VLANs that we're not a part of, further reducing the number of extraneous packets recieved. This makes use of the VLAN virtqueue command class. The CTRL_VLAN feature bit tells us whether the backend supports VLAN filtering.

* virtio_net: Add a MAC filter tableAlex Williamson2009-02-04
| | | | | | | | | | | | | Make use of the MAC control virtqueue class to support a MAC filter table. The filter table is managed by the hypervisor. We consider the table to be available if the CTRL_RX feature bit is set. We leave it to the hypervisor to manage the table and enable promiscuous or all-multi mode as necessary depending on the resources available to it.

* virtio_net: Add a set_rx_mode interfaceAlex Williamson2009-02-04
| | | | | | | | | | | | | Make use of the RX_MODE control virtqueue class to enable the set_rx_mode netdev interface. This allows us to selectively enable/disable promiscuous and allmulti mode so we don't see packets we don't want. For now, we automatically enable these as needed if additional unicast or multicast addresses are requested.

* virtio_net: Add a virtqueue for outbound control commandsAlex Williamson2009-02-04
| | | | | | | | | | | | | | | | | | | | This will be used for RX mode, MAC filter table, VLAN filtering, etc... The control transaction consists of one or more "out" sg entries and one or more "in" sg entries. The first out entry contains a header defining the class and command. Additional out entries may provide data for the command. The last in entry provides a status response back from the command. Virtqueues typically run asynchronous, running a callback function when there's data in the channel. We can't readily make use of this in the command paths where we need to use this. Instead, we kick the virtqueue and spin. The kick causes an I/O write, triggering an immediate trap into the hypervisor.

| * b43: Dynamically control log verbosityMichael Buesch2009-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dynamically control the log verbosity with a module parameter. This enables us to dynamically enable debugging messages (or disable info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose. This increases the module size by about 3k. But in practice it reduces the module size for the user, because some distributions ship the b43 module with CONFIG_B43_DEBUG set, which increases the module by about 15k. So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG. There is no reason to keep it in a production-release kernel. So we have a net reduction in size by about 12k. This patch also adds a printk of the wireless core revision, so people don't have to enable SSB debugging to get the wireless core revision.

| * mac80211: change workqueue back to non-freezeableBob Copeland2009-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "mac80211: make workqueue freezable" made the mac80211 workqueue freezeable to prevent us from doing any work after the driver went away. This was fine before mac80211 had any suspend support. However, now we want to flush this workqueue in suspend(). Because the thread for a freezeable workqueue is stopped before the device class suspend() is called, flush_workqueue() will hang in the suspend-to-disk case. Converting it back to a non-freezeable queue will keep suspend from hanging. Moreover, since we flush the workqueue under RTNL and userspace is stopped, there won't be any new work in the workqueue until after resume. Thus we still don't have to worry about pinging the AP without hardware. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * mac80211: Fixed BSSID handling revisitedAlina Friedrichsen2009-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleanup the fixed BSSID handling, that ieee80211_sta_set_bssid() works like ieee80211_sta_set_ssid(). So that the BSSID is only a second selection criterion besides the SSID. This allows us to create new IBSS networks with fixed BSSIDs, which was broken before. In the second version of this patch the handling of the stupid merges to the same BSSID is moved out to get reworked into an other patch. And this version hopefully solves the problems with some low-level drivers and re-adds the config BSSID warning to help debugging the low-level drivers.
