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.

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: NFelix Fietkau <nbd@openwrt.org> Signed-off-by: NJohn 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).

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: Npieter-paul giesberts <pieterpg@broadcom.com> Reviewed-by: Narend van spriel <arend@broadcom.com> Signed-off-by: Nfranky lin <frankyl@broadcom.com> Signed-off-by: NFranky Lin <frankyl@broadcom.com> Signed-off-by: NJohn W.

Drivers need the station rate info when inserting a new sta_info. The patch "mac80211: refactor mesh peer initialization" wrongly assumed the rate info could be applied after insertion. After further review, this is clearly not the case. This fixes a regression where HT parameters were not applied before inserting the sta_info, causing performance degradation.

This is a cut and paste mistake, sizeof(struct mib_local) was intended instead of sizeof(struct mib_phy). The call to at76_get_mib() uses sizeof(struct mib_local) correctly, although I changed that to sizeof(*m) for style reasons after discussion with some of the wireless maintainers. The current code works fine because mib_phy structs are larger than mib_local structs. But we may as well clean it up. Signed-off-by: NDan Carpenter <dan.carpenter@oracle.com> Signed-off-by: NJohn W.
