* net: Add ndo_{set|get}_vf_port support for enic dynamic vnicsScott Feldman2010-05-189-24/+521
| | | | | | | | | | | | | | | | | | | Add enic ndo_{set|get}_vf_port ops to support setting/getting port-profile for enic dynamic devices. Enic dynamic devices are just like normal enic eth devices except dynamic enics require an extra configuration step to assign a port-profile identifier to the interface before the interface is useable. Once a port-profile is assigned, link comes up on the interface and is ready for I/O. The port-profile is used to configure the network port assigned to the interface. The network port configuration includes VLAN membership, QoS policies, and port security settings typical of a data center network. A dynamic enic initially has a zero-mac address. Before a port-profile is assigned, a valid non-zero unicast mac address should be assign to the dynamic enic interface.

* can: sja1000 platform data fixesWolfgang Grandegger2010-05-181-1/+2
| | | | | | | | | | | | | | The member "clock" of struct "sja1000_platform_data" is documented as "CAN bus oscillator frequency in Hz" but it's actually used as the CAN clock frequency, which is half of it. To avoid further confusion, this patch fixes it by renaming the member to "osc_freq". That way, also non mainline users will notice the change. The platform code for the relevant boards is updated accordingly. Furthermore, pre-defined values are now used for the members "ocr" and "cdr".

Also, instead of dropping them immediately though move the check *after* we check for all sort of frame errors. This should enable us to discard these frames if the hardware picks other bogus items first. Lets see if we still get those jumbo counters increasing still with this. Jumbo frames would happen if we tell hardware we can support a small 802.11 chunks of DMA'd frame, hardware would split RX'd frames into parts and we'd have to reconstruct them in software. This is done with USB due to the bulk size but with ath5k we already provide a good limit to hardware and this should not be happening. This is reported quite often and if it fills the logs then this needs to be addressed and to avoid spurious reports. Cc: stable@kernel.org Signed-off-by: Luis R.

| | * iwlwifi: use iwl_find_station lessJohannes Berg2010-05-115-78/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we now store the station ID in each station struct, many places need not look at the station table any more since they can just pull the station ID out of the struct. Remove iwl_get_sta_id() and use iwl_sta_id() instead as appropriate. This reduces the amount of code needed to find the right station significantly, and works since mac80211 passes the station only after it has been fully initialised, ie. even if TX races with station addition it will only be passed to TX once the addition is complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 allows us to store private data per station, so put the station ID there. This allows us to avoid the station ID lookup when removing regular stations. To also be able to avoid the lookup to remove the special IBSS BSSID station, track its ID in the per-vif private data.

| | * iwlagn: work around rate scaling reset delayReinette Chatre2010-05-111-1/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When station is using an HT channel to communicate to AP and communication is lost then driver will first be notified that channel is not an HT channel anymore before AP station is removed. A consequence of that is that the driver will know that it is not communicating on HT anymore, but the rate scaling table is still under the impression it is operating in HT. Any time after driver has been notified channel is not HT anymore there will thus be a firmware SYSASSERT when the current active LQ command is sent. A workaround for this issue is to not send a LQ command in the short time between being notified channel is not HT anymore and rate scaling table being updated.

| | * iwlwifi: rework broadcast station managementJohannes Berg2010-05-1111-99/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the broadcast station is managed along with the interface type, rather than always being present. That leads to a bug with injection -- it is currently not possible to inject frames when the only virtual interface is a monitor, because in that the required broadcast station is missing. Additionally, allocating and deallocating the broadcast station's LQ all the time is wasteful, and the code to support this is fairly complex. So this changes completely the way we manage the broadcast station. Rather than manage it along with any interface, we now allocate it when we bring the device up, and remove it again when we bring the device down. When we bring the device up, we don't immediately program the broadcast station into it, instead we just mark it active and rely on the next restore cycle to upload it to the device. This works because an unassociated RXON is always required at least once to set up device parameters, which implies a reprogramming of stations into the device. As we now manage all stations properly, there no longer is a need for forcing a clearing of them via iwl_clear_ucode_stations(), which can become a lot simpler.
