* iwlwifi: split the drivers for agn and legacy devices 3945/4965Wey-Yi Guy2011-02-211-2666/+0
| | | | | | | | | | | | | | | | | | Intel WiFi devices 3945 and 4965 now have their own driver in the folder drivers/net/wireless/iwlegacy Add support to build these drivers independently of the driver for AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko, and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko contains code shared between both devices. The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3 ABGN device.

* | iwlwifi: do not set tx power when channel is changingStanislaw Gruszka2011-01-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Mac80211 can request for tx power and channel change in one ->config call. If that happens, *_send_tx_power functions will try to setup tx power for old channel, what can be not correct because we already change the band. I.e error "Failed to get channel info for channel 140 [0]", can be printed frequently when operating in software scanning mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | In order to simplify the flow, and make new enhancements easier, separate out the RXON processing for modern AGN (5000 and newer) from RXON processing for the older 3945 and 4965 devices. Avoid changing these old ones to avoid regressions and move their code to a new file (iwl-legacy.c). 4965 gets the commit_rxon that used to be common for all AGN devices, but with removed PAN support. The new RXON processing is more central and does more work in committing, so that it is easier to follow. To make it more evident what is split out for legacy, split the necessary operations for that into a new struct iwl_legacy_ops. Those parts that still exist in the new AGN code don't need to be parametrized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the driver will try to protect all frames, which leads to a lot of odd things like sending an RTS with a zeroed RA before multicast frames, which is clearly bogus. In order to fix all of this, we need to take a step back and see what we need to achieve: * we need RTS/CTS protection if requested by the AP for the BSS, mac80211 tells us this * in that case, CTS-to-self should only be enabled when mac80211 tells us * additionally, as a hardware workaround, on some devices we have to protect aggregated frames with RTS To achieve the first two items, set up the RXON accordingly and set the protection required flag in the transmit command when mac80211 requests protection for the frame. To achieve the last item, set the rate-control RTS-requested flag for all stations that we have aggregation sessions with, and set the protection required flag when sending aggregated frames (on those devices where this is required). Since otherwise bugs can occur, do not allow the user to override the RTS-for-aggregation setting from sysfs any more. Finally, also clean up the way all these flags get set in the driver and move everything into the device-specific functions.

Because of when this occurs, this is the 2.4 GHz band and uses the 0x420a (CCK, 1 Mbps) rate. In 5 GHz beaconing mode, this rate will prevent beacons from being sent and any other packets from being received. We can fix this by re-initializing the bcast station's LQ command when the channel is changed.

* iwlwifi: reduce memory allocationJohannes Berg2010-06-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the driver allocates up to 19 skb pointers for each TFD, of which we have 256 per queue. This means that for each TX queue, we allocate 19k/38k (an order 4 or 5 allocation on 32/64 bit respectively) just for each queue's "txb" array, which contains only the SKB pointers. However, due to the way we use these pointers only the first one can ever be assigned. When the driver was initially written, the idea was that it could be passed multiple SKBs for each TFD and attach all those to implement gather DMA. However, due to constraints in the userspace API and lack of TCP/IP level checksumming in the device, this is in fact not possible. And even if it were, the SKBs would be chained, and we wouldn't need to keep pointers to each anyway. Change this to only keep track of one SKB per TFD, and thereby reduce memory consumption to just one pointer per TFD, which is an order 0 allocation per transmit queue.
