wl reads radio version, then disables it. That's how we found it in MMIO dump: radio_read(0x0000) -> 0x0031 <-- RADIO READ WITHOUT 0x200 SET! radio_read(0x0001) -> 0x0064 <-- RADIO READ WITHOUT 0x200 SET! radio_read(0x0002) -> 0x0020 <-- RADIO READ WITHOUT 0x200 SET! read32 0xfaafc120 -> 0x04000400 phy_read(0x044d) -> 0x0000 phy_write(0x044d) <- 0x0000 phy_read(0x044c) -> 0x1fff phy_write(0x044c) <- 0x1fff phy_read(0x04b7) -> 0x0000 phy_write(0x04b7) <- 0x0000 phy_read(0x04b1) -> 0x0000 phy_write(0x04b1) <- 0x0000 phy_read(0x04b0) -> 0x7dff phy_write(0x04b0) <- 0x7dff phy_read(0x04fa) -> 0x0000 phy_write(0x04fa) <- 0x0000 phy_read(0x04f9) -> 0x007f phy_write(0x04f9) <- 0x007f Signed-off-by:

On embedded hardware it's normal to not have a PCI device for the PCI bridge that the wifi card is attached to. pdev->bus->self will be NULL in that case. In that case, simply return without emitting an useless kernel stack trace. Signed-off-by:

While switching b/w HT20/40, the current channel's nf values are updated into history buffer. Since the current channel's channel type, channel flag got updated before reading nf value from hw. This channel type mismatch is causing invalid readings when hw is on ht20 but getnf tries to read on extn chains. Signed-off-by:

Before doing hw reset the current channel's noisefloor readings are updated into history buffer. The extension chain's readings are considered only if the current channel was configured in HT40. While moving from HT40 to HT20, the extn chain's readings are skipped though the current channel is in ht40. This patch updates extn chain reading based on channel flag. Signed-off-by:

Whenever RXEOL is received, both RXORN and RXEOL got cleared to avoid rx overrun interrupt storm. This was handled only for edma chips. The same scenario was also observered with AR9280, doing frequent channel type switch b/w HT20/40 with bidi traffic that is causing failure to stop rx dma. This patch clears the RXEOL & RXORN interrupts for all chips. ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 DMADBG_7=0x000062c0 ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:532 ath_stoprecv+0x110/0x120 [ath9k]() Call Trace: [<ffffffff8104a55a>] warn_slowpath_common+0x7a/0xb0 [<ffffffff8104a5a5>] warn_slowpath_null+0x15/0x20 [<ffffffffa0560380>] ath_stoprecv+0x110/0x120 [ath9k] [<ffffffffa055e6fa>] ath_reset+0x6a/0x200 [ath9k] Signed-off-by:

The WAR which adds extra delimiters when using RTS/CTS with aggregation and non-enterprise AR9003 chips. This extra padding is done after doing all the 4ms limit checks and hence the total aggregate sizes are exceeding the allowed duration. This patch limits the aggregate sizes appropriately after including these extra delimiters. Signed-off-by:

In this implementation, a mesh gate is a root node with a certain bit set in its RANN flags. The mpath to this root node is marked as a path to a gate, and added to our list of known gates for this if_mesh. Once a path discovery process fails, we forward the unresolved frames to a known gate. Thanks to Luis Rodriguez for refactoring and bug fix help. Signed-off-by:

MMIO hacks were used to trick ndis&wl. For example following: phy_read(0x0280) -> 0xffff phy_write(0x0280) <- 0xff3e *** phy_read(0x0280) -> 0x0000 phy_write(0x0280) <- 0x003e was translated to mask 0xff00 and set 0x3e. Signed-off-by:

When a client disassociates from a crypto enabled bss, data traffic to other clients connected to the bss is stalled. This was due to a boolean variable used to keep track if HW crypto is enabled i.e. if set key has been called to add a key. This flag was being reset every time delete key was called e.g when a station leaves the bss. Once the flag is reset, rx status flags were not being set for connected clients which disrupts traffic to these clients. Fix this issue by not resetting the flag since we do not need to reset this flag during the life time of the bss. Signed-off-by:

This patch updates the mesh peering frames to the format specified in the recently ratified 802.11s standard. Several changes took place to make this happen: - Change RX path to handle new self-protected frames - Add new Peering management IE - Remove old Peer Link IE - Remove old plink_action field in ieee80211_mgmt header These changes by themselves would either break peering, or work by coincidence, so squash them all into this patch.
