The u32 would never be less than zero so the error handling would break. I changed it to s32 to match how bcma_erom_get_mst_port() is declared. Signed-off-by:

We have resolved all the known issues with DMA mode, however some users (or distros) are still forcing PIO mode by config files. Without debugging enabled it's not noticable at all. Add the warning for them. Cc: Gregory Bellier <gregory.bellier@gmail.com> Signed-off-by:

All AR9170 hardware have a 16-Bit random number generator. The documentation claims the values are suitable for "security keys". The "throughput" is around 320Kibit/s. It's slow, but it does work without introducing any special offload firmware commands. Signed-off-by:

AR9170_PWR_REG_PLL_ADDAC is used to set the main clock divisor which affects the AHB/CPU speed. Because this would interfere with the firmware internal timekeeping, the function has to be moved into the firmware. 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:
