* Bluetooth: Remove redundant hdev->parent fieldDavid Herrmann2012-05-093-4/+2
| | | | | | | | | | | | | | | | We initialize the "struct device" in hci_alloc_dev() for a long time now so we can access hdev->dev.parent directly. Hence, we can drop the temporary field hdev->parent which is used in no other place than hci_add_sysfs(). SET_HCIDEV_DEV() is never called after registering a device by the drivers so we do not overwrite internal device-state. Furthermore, hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the default behavior with dev.parent = NULL is kept.

* mac80211: Implement HT mixed protection modeAshok Nagarajan2012-05-082-7/+77
| | | | | | | | | | | | | | | | | | Section 9.23.3.5 of IEEE 80211s standard describes the protection rules for HT mesh STA in a MBSS. Three HT protection modes are supported for now: non-HT mixed mode - is selected if any non-HT peers are present in our MBSS. 20MHz-protection mode - is selected if all peers in our 20/40MHz MBSS support HT and atleast one HT20 peer is present. no-protection mode - is selected otherwise. This is a limited implementation of 9.23.3.5, which only considers mesh peers when determining the HT protection mode. Station's channel_type needs to be maintained.

* cfg80211: fix BSS comparisonEmmanuel Grumbach2012-05-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Since the BSS table is organized in a RB tree, the BSSs need to be comparable. This means that we must define a < and > operator to the BSS object. compare_ethr_addr isn't enough since it returns only a binary value. Since Felix's cfg80211: use compare_ether_addr on MAC addresses instead of memcmp Because of the constant size and guaranteed 16 bit alignment, the inline compare_ether_addr function is much cheaper than calling memcmp. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com> The BSS table is corrupted: rb_find_bss can't find the bss. As a result BSSes are duplicated in the BSS table, and we get stuck while probing an AP before associating (in STA mode).

* brcmfmac: add out of band interrupt supportFranky Lin2012-05-085-15/+240
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some sdio host controllers do not support real in band interrupt. Software polling mode as a replacement is not fast enough for high throughput and new features. Also some in band interrupts do not support host wake up on embedded platform even when they are real physical interrupts. Therefore out of band (oob) interrupt mechanism is implemented for these scenarios. To provide oob irq number and flags used for irq registration in brcmfmac, a platform device contains irq resource must be registered in board specific code. Here is an example of platform device structure: struct resource brcmf_sdio_res[] = { { .start = GPIO_BRCMF_SDIO_OOB_NUM, .end = GPIO_BRCMF_SDIO_OOB_NUM, .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL, } }; struct platform_device brcmf_sdio_device = { .name = "brcmf_sdio_pd", .id = -1, .num_resources = ARRAY_SIZE(brcmf_sdio_res), .resource = brcmf_sdio_res, }; Reviewed-by: pieter-paul giesberts <pieterpg@broadcom.com> Reviewed-by: arend van spriel <arend@broadcom.com> Signed-off-by: franky lin <frankyl@broadcom.com> Signed-off-by: Franky Lin <frankyl@broadcom.com> Signed-off-by: John W.
