* vxge: Fix starvation of receive ring controller when blasted by short packets.Sreenivasa Honnur2010-03-293-13/+6
| | | | | | | | | | | | - Fix starvation of receive ring controller when blasted by short packets. This was because the driver was posting 64 rxds initially while the ring controller was expecting to read 256 replenished rxds. While the driver was coming up, the internal rxd memory filled up the 64 buffers provided and the ring controller was left waiting for the remaining 192 rxds to complete the write back of completed rxds to the host and generation of an interrupt.

* vxge: Fix a receive stall due to driver being out of synch with chip.Sreenivasa Honnur2010-03-292-7/+56
| | | | | | | | | | | | | | | | | - Fix a receive stall due to driver being out of synch with chip. In a corner case scenario the adapter's ring controller may return a RxD with transfer code of 0xC, while the host ownership bit is still set to the adapter. The driver needs to assume that this case where (host_ownership == 1 or adapter) and (transfer_code == 0xC) is valid, that is, this RxD has been returned by the receive ring controller but no frame data is associated with the rxd. - Restore the transfer code field of each newly replenished RxD to 0x0. - Code cleanup. Removed usage of magic numbers. Signed-off-by: Sreenivasa Honnur <sreenivasa.honnur@neterion.com> Signed-off-by: Ramkrishna Vepa <ram.vepa@neterion.com> Signed-off-by: David S.

The history buffer supports collecting information for all Atheros hardware, one history buffer slot for each chain on each channel used for MIMO operation. For current hardware this means one history buffer slot for each chain on both the control (or primary) channel and the extension (or secondary) channel. We know which noisefloor registers to poke for collecting noisefloor data through the chainmask. For AR9285 and AR9271 devices, both 1x1, the chaimmask is defined as 0x9 = 0b0001001. The first four bits represent each chain out of a maximum of 4 chains [0-3] on the primary channel. The last four bits represent each chain on the extension channel. A chainmask of 0x9 therefore indicates chain 1 is active on both the primary and the extension channel. AR9271 only requires collecting and storing noisefloor history buffer data for the first chain on both the control and extension channel (nfarray[0] and nfarray[3]) so fix the code and avoid which reads and writes to the history buffer for the other chains. Since the noisefloor varies depending on the number of chains your device supports also initialize the noisefloor history buffer with reasonable values seen on 1x1 devices such as AR9285.

| * iwlwifi: code cleanup for connectivity recoveryWey-Yi Guy2010-03-196-40/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the connectivity check and recovery routine into separated functions based on the types 1. iwl_good_ack_health() - check for ack count 2. iwl_good_plcp_health() - check for plcp error Based on the type of errors being detected, different recovery methods will be used to bring the system back to normal operational state. Because different NIC has different HW and uCode, the behavior is also different; these functions thus now form part of the ops infrastructure, so we can have more control on how to monitor and recover from error condition case per device.

| * iwlwifi: Recover TX flow failureWey-Yi Guy2010-03-193-2/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Monitors the tx statistics to detect the drop in throughput. When the throughput drops, the ratio of the actual_ack_count and the expected_ack_count also drops. At the same time, the aggregated ba_timeout (the number of ba timeout retries) also rises. If the actual_ack_count/expected_ack_count ratio is 0 and the number of ba timeout retries rises to BA_TIMEOUT_MAX, no tx packets can be delivered. Reloading the uCode and bring the system back to normal operational state.

| * iwlwifi: Recover TX flow stall due to stuck queueWey-Yi Guy2010-03-1911-0/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Monitors the internal TX queues periodically. When a queue is stuck for some unknown conditions causing the throughput to drop and the transfer is stop, the driver will force firmware reload and bring the system back to normal operational state. The iwlwifi devices behave differently in this regard so this feature is made part of the ops infrastructure so we can have more control on how to monitor and recover from tx queue stall case per device.
