* [netdrvr] sfc: Add phy_flash_cfg module parameter and implementationBen Hutchings2008-05-13
| | | | | | | | | The 10Xpress PHY supports flash upgrades through MDIO, but needs to be put in upgrade mode at power-up. This adds a module parameter and other logic to support that. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* [netdrvr] sfc: Add TSO supportBen Hutchings2008-05-13
| | | | | | | | | | The SFC4000 controller does not have hardware support for TSO, and the core GSO code incurs a high cost in allocating and freeing skbs. This TSO implementation uses lightweight packet header structures and is substantially faster. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

* myri10ge: fix the number of interrupt slotsBrice Goglin2008-05-13
| | | | | | | | | | | | Fix a long-standing bug/misunderstanding between the driver and the firmware. The size of the interrupt queue must be set to the number of rx slots (big + small), and it should never have been a tunable. Setting it too small results in chaos.

| | | | | | | | | | | Make ethtool report FIBER for XFP based NIC's port type.

* myri10ge: increase and fix handoff timeoutBrice Goglin2008-05-13
| | | | | | | | | | | | | | Increase the handoff timeout to 512ms so as to give the aeluros based NICs sufficient time to handoff without relying on the msleep() being sloppy, and accidentally sleeping way longer than the 20ms we specified in 20 separate 1ms sleeps. Fix typo in the handoff sleep delay, which made it additive, not exponential.

| * mac80211: fix association with some APsHelmut Schaa2008-05-12
| | | | | | | | | | | | | | | | | | | | | | Some APs refuse association if the supported rates contained in the association request do not match its own supported rates. This patch introduces a new function which builds the intersection between the AP's supported rates and the client's supported rates to work around such problems. The same approach is already used in ipw2200 for example. Signed-off-by: Helmut Schaa <hschaa@suse.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * zd1211rw: fix potential use-after-free bugJohannes Berg2008-05-12
| | | | | | | | | | | | | | | | | | zd_mac_tx_to_dev() could potentially free the skb, or hand it off to mac80211 which might free it. Hence, this code needs to get the usb pointer out of skb->cb before handing it off to that function. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | Calling synchronize_rcu() under write-lock-ed pathtbl_resize_lock may result in this warning (and other side effects). It looks safe just dropping this lock before calling synchronize_rcu. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * Fix GFP_KERNEL allocation under read lock.Pavel Emelyanov2008-05-12
| | | | | | | | | | | | | | | | | | | | | | | | The mesh_path_add() read-locks the pathtbl_resize_lock and calls kmalloc with GFP_KERNEL mask. Fix it and move the endadd2 label lower. It should be _before_ the if() beyond, but it makes no sense for it being there, so I move it right after this if(). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: John W.

| * mac80211: Don't encrypt beaconsIvo van Doorn2008-05-12
| | | | | | | | | | | | | | | | | | | | mac80211 should set the IEEE80211_TX_CTL_DO_NOT_ENCRYPT flag in tx_control structure to inform drivers not to encrypt the beacon. Drivers that only check for that flag before accessing the hw_key field, will otherwise cause a NULL pointer dereference since that field is not configured for beacons.

| * rt2x00: Clean up error handling of PCI queue DMA allocation.Ivo van Doorn2008-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When, for some reason, the rt2x00pci module fails to allocate DMA memory for the queues, it tries to undo the complete initialization of the PCI device, including freeing of the irq. This results in the following error in dmesg, as the irq hadn't been requested yet: [ 78.123456] Trying to free already-free IRQ 17 Fix this by implementing proper error handling code, instead of just using the full uninitialization function.

| * rt2x00: Fix broken recover-on-error pathIvo van Doorn2008-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | During initialization the initialize() callback function in rt2x00pci and rt2x00usb will cleanup the mess they made. rt2x00lib shouldn't call uninitialize because the callback function already cleaned up _and_ the DEVICE_INITIALIZED isn't set which causes the rt2x00lib_uninitialize() to halt directly anyway. All that is required to be cleaned up by rt2x00lib is the queue, and that can be done by calling rt2x00queue_uninitialize() directly.

| * rt2x00: Don't use pskb_expand_head()Ivo van Doorn2008-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rt2x00pci allocates DMA for descriptor and data, rt61pci doesn't use this for the beacon, but it can use the descriptor part as temporary buffer instead of using pskb_expand_head(). Using this temporary buffer is obviously much better then reallocating the skb buffer... At the same time we can set the data length for the beacon queue at 0, to make sure no DMA is allocated for data (but just for the descriptor).
