2009-10-27iwmc3200wifi: Do not handle wifi command if the interface is not readySamuel Ortiz1-0/+5

2009-10-27iwmc3200wifi: Check for cmd pointer before dereferencing itSamuel Ortiz1-2/+8
The wifi_if_wrapper notification handling code uses a cmd pointer without checking if it's valid or not. We're dereferencing it because we assume that we only get to that point if there was a pending command for us. That's not always true, so we'd better check.

2009-10-27iwmc3200wifi: SDIO disable race fixSamuel Ortiz1-2/+2
When calling sdio->bus_disable(), we are flushing the command lists before disabling the sdio function. We can thus potentially get a command response after having flushed the command list. To avoid that race, we have to call iwm_reset() after disabling the sdio function. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

We were not handling endianess correctly. The wl1271 chip runs on little-endian values. This patch makes sure that all the communication with the wl1271 firmware is done in little-endian by using cpu_to_le* and le*_to_cpu where appropriate. Also, all the struct definitions for data exchanged with the firmware has been changed to use __le16/32 types instead of u16/32.

2009-10-27iwlwifi: use paged RxZhu Yi15-240/+284
This switches the iwlwifi driver to use paged skb from linear skb for Rx buffer. So that it relieves some Rx buffer allocation pressure for the memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for Rx buffer. Due to the trailing skb_shared_info in the skb->data, alloc_skb() will do the next order allocation, which is 16K bytes. This is suboptimal and more likely to fail when the system is under memory usage pressure. Switching to paged Rx skb lets us allocate the RXB directly by alloc_pages(), so that only order 1 allocation is required. It also adjusts the area spin_lock (with IRQ disabled) protected in the tasklet because tasklet guarentees to run only on one CPU and the new unprotected code can be preempted by the IRQ handler. This saves us from spawning another workqueue to make skb_linearize/__pskb_pull_tail happy (which cannot be called in hard irq context). Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb for all the management frames and software decryption or defragmentation required data frames before handed to mac80211. For all the other frames, we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211 to handle them properly. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

2009-10-27wl1271: remove unnecessary joins and join only when the bssid changesLuciano Coelho3-45/+24
We were using the join command to change some settings when the stack asked us to do it. In many cases they were not needed (and could cause potential problems), so they were removed. In other cases there are ACX commands that can be used instead of using join to reconfigure.
