Fix this issue by not reporting MIC errors for unicast frames with a valid key, letting mac80211 validate the MIC instead. Additionally, strip the MIC for all frames that the hardware considers valid to avoid wasting CPU cycles re-validating it. Signed-off-by: Felix Fietkau Signed-off-by: John W.

I would prefer the upper layer to receive a pointer to an iwl_rx_packet, but this is impossible since the Rx path needs to add the address of the page to the skb. I may find a solution later.

These get + * used not only for Rx frames, but for any command response or notification + * from the NIC. The driver and NIC manage the Rx buffers by means + * of indexes into the circular buffer. + * + * Rx Queue Indexes + * The host/firmware share two index registers for managing the Rx buffers. + * + * The READ index maps to the first position that the firmware may be writing + * to -- the driver can read up to (but not including) this position and get + * good data. + * The READ index is managed by the firmware once the card is enabled. + * + * The WRITE index maps to the last position the driver has read from -- the + * position preceding WRITE is the last slot the firmware can place a packet. + * + * The queue is empty (no good data) if WRITE = READ - 1, and is full if + * WRITE = READ. + * + * During initialization, the host sets up the READ queue position to the first + * INDEX position, and WRITE to the last (READ - 1 wrapped) + * + * When the firmware places a packet in a buffer, it will advance the READ index + * and fire the RX interrupt. The driver can then query the READ index and + * process as many packets as possible, moving the WRITE index forward as it + * resets the Rx queue buffers with new memory. + * + * The management in the driver is as follows: + * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free. When + * iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled + * to replenish the iwl->rxq->rx_free. + * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the + * iwl->rxq is replenished and the READ INDEX is updated (updating the + * 'processed' and 'read' driver indexes as well) + * + A received packet is processed and handed to the kernel network stack, + * detached from the iwl->rxq. The driver 'processed' index is updated. + * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free + * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ + * INDEX is not incremented and iwl->status(RX_STALLED) is set. If there + * were enough free buffers and RX_STALLED is set it is cleared. + * + * + * Driver sequence: + * + * iwl_rx_queue_alloc() Allocates rx_free + * iwl_rx_replenish() Replenishes rx_free list from rx_used, and calls + * iwl_rx_queue_restock + * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx + * queue, updates firmware pointers, and updates + * the WRITE index.

This duplication is historical and is not needed anymore. Keep the name "ath5k_hw" for the merged structure and "ah" for the variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more descriptive and more widely used. Put the combined structure to ath5k.h where the old ath5k_softc used to be. Move some code from base.h to ath5k.h as needed. Remove memory allocation for struct ath5k_hw and the corresponding error handling. Merge iobase and ah_iobase fields.

This means that the bus layer assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to iwl_probe. The device specific struct is allocated together with the common iwl_bus struct by the bus specific layer. The pointer to the aggregate struct is passed to the upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus. The private data given to the PCI subsystem is now iwl_bus and not iwl_priv. Provide bus_* inliners on the way in order to simplify the syntax. Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the external of the bus layer.

To fix all this, modify the way keys are sent to the device and key offsets are allocated. After these changes, key offsets are stored into the hw_key_idx which we can then track for the key lifetime, not relying on our sta_cmd array. WEP default keys get special treatment, of course. Additionally, since I had the API for it, we can now pre-fill TKIP phase 1 keys for RX now that we can obtain the P1K from mac80211, a capability I had added for WoWLAN initially. Finally, some keys simply don't need to be added into the device's key cache -- a key that won't be used for RX is only needed in the TX header, so "pretend" to have accepted any key without adding it into the device -- no need to use up key space there for it.
