In the receive path a spinlock is taken upon parsing the TLV signal header. This moves to locking to the TLV handling functions where it protects the data structures. Reviewed-by:

Transmit packets needs to be tagged in order to receive a tx status feedback from the firmware. Determine the tag in the netdev transmit callback instead of determining the tag just before transfer to the device. This reduces the number of exception flows and hence makes the driver code simpler. Reviewed-by:

DMA engine of some old SDIO host controllers require block size alignment for data length of each scatterlist item. This patch introduces an intermediate buffer list to support this kind of platform. It decreases the throughput because of an extra memcpy in critical data path. So don't turn this on unless it's necessary. Reviewed-by:

When getting a transmit packet from the networking layer simply enqueue the packet unconditional and have it handled by the dequeue worker. The transfer of the packet to the bus-specific driver part is now done from one context. Reviewed-by:

Apparently HW doesn't require us to generate MMIC for TKIP suite. Each frame was 8 bytes longer than it should be and some APs would drop frames that exceed 1520 bytes of 802.11 payload. This could be observed during throughput tests or fragmented IP traffic. Signed-off-by:

The code writes the default_power2 value into the TX field of the RFCSR50 register, however the condition in the if statement uses default_power1. Due to this, wrong TX power value might be written into the register. Use the correct value in the condition to fix the issue. Compile tested only. Signed-off-by:

Ralink 3T chipsets are using a different EEPROM layout than the others. The EEPROM on these devices contain more data than the others which does not fit into 272 byte which the rt2800 driver actually uses. The Ralink reference driver defines EEPROM_SIZE to 512/1024 bytes for PCI/USB devices respectively. Increase the EEPROM_SIZE constant to 512 bytes, in order to make room for EEPROM data of 3T devices. Signed-off-by:

To improve power consumption in idle associated mode FW may lower RX power. This low linearity mode is acceptable for listening low rate RX such as beacons and groupcast. The driver enables LPRX only if PM is enabled and associated AP's beacon TX rate is 1Mbps or 6Mbps. LPRX RSSI threshold is used to limit a range where LPRX is applied. Signed-off-by:

The PCIe code has an array of buffer descriptors (RXBs) that have pages and DMA mappings attached. In regular use, the array isn't used and the buffers are either on the hardware receive queue or the rx_free/rx_used lists for recycling. Occasionally, during module unload, we'd see a warning from this: WARNING: at lib/list_debug.c:32 __list_add+0x91/0xa0() list_add corruption. prev->next should be next (c31c98cc), but was c31c80bc. (prev=c31c80bc). Pid: 519, comm: rmmod Tainted: G W O 3.4.24-dev #3 Call Trace: [<c10335b2>] warn_slowpath_common+0x72/0xa0 [<c1033683>] warn_slowpath_fmt+0x33/0x40 [<c12e31d1>] __list_add+0x91/0xa0 [<fdf2083c>] iwl_pcie_rxq_free_rbs+0xcc/0xe0 [iwlwifi] [<fdf21b3f>] iwl_pcie_rx_free+0x3f/0x210 [iwlwifi] [<fdf2dd7a>] iwl_trans_pcie_free+0x2a/0x90 [iwlwifi] The reason for this seems to be that in iwl_pcie_rxq_free_rbs() we use the array to free all buffers (the hardware receive queue isn't in use any more at this point). The function also adds all buffers to rx_used because it's also used during initialisation (when no freeing happens.) This can cause the warning because it may add entries to the list that are already on it. Luckily, this is harmless because it can only happen when the entire data structure is freed anyway, since during init both lists are initialized from scratch. Disentangle this code and treat init and free separately. During init we just need to put them onto the list after freeing all buffers (for switching between 4k/8k buffers); during free no list manipulations are necessary at all. Reviewed-by:

In case that an AP/GO interface is started while there is a station/P2P client associated, need to make sure that the AP/GO beacon time is far enough from the station's one in oder to allow the station to receive the DTIM beacons and the following traffic etc. To resolve this, when the AP is started, check if there is an active station interface, and guarantee that the AP/GO TBTT is far enough from the station one.

The vring index (MAC queue id) must be set in all TX descriptors otherwise HW will fail to release descriptors for a specific vring (disconnect or vring switch flows). This is normally occurs when fragmentation required, if vring index will not be the same for all SKB descriptors HW will fail to flush this MAC queue. Signed-off-by:

The current code uses the same index value both for the channel information array and for the TX power table. The index starts from 14, however the index of the TX power table must start from zero.
