2012-09-12brcmfmac: add e-scan support.Hante Meuleman5-2/+583
This patch adds e-scan support (currently i-scan is in use). E-scan is a more powerful and memory efficient method for scanning. E-scan will be the default scan method and eventually, i-scan support will be removed. The scan methods do not make any difference to the end-user.

2012-09-11libertas: set mac control synchronously during initDaniel Drake3-1/+20
CMD_MAC_CONTROL is currently sent async to the firmware, and is sent from the lbs_setup_firmware() path during device init. This means that device init can complete with commands pending, and the if_sdio driver will sometimes power down the device (after init) with this command still pending. This was causing an occasional spurious command timeout after init, leading to a device reset. Fix this by making CMD_MAC_CONTROL synchronous when called from the lbs_setup_firmware() path.

2012-09-11mwifiex: update adapter->bss_prio_tbl[j].bss_prio_cur correctlyAmitkumar Karwar1-5/+4
"adapter->bss_prio_tbl[j].bss_prio_head" points to linked list of interfaces with priority 'j'. "bss_prio_tbl[j].bss_prio_cur" is supposed to point to next interface every time the routine for dequeuing the packet is called. This ensures that each interface gets fair chance. Currently we have AP and station interfaces with priority '0'. Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should alternately point to AP and station nodes. Since "bss_prio_cur" is not correctly updated, for each packet picked for AP, two packets are picked for station interface. This patch fixes the problem by correctly updating "bss_prio_cur".

2012-09-11mwifiex: have same priority for AP and station trafficAmitkumar Karwar2-3/+2
Currently AP interface has higher priority over station. Hence separate entries are created in "adapter->bss_prio_tbl" for these interfaces and station packet is dequeued only if there is not packet in queue for AP. It is observed that ping for station interface doesn't work if heavy traffic is running on AP. The problem is fixed by having same priority for both the interfaces. This patch also removes an extra initialisation for "priv->bss_priority". Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.
