Ben Greear 462e58f2b6 ath9k: Gather and report IRQ sync_cause errors.
Report all defined sync_cause errors in debugfs
to aid with debugging.

Use a macro to print out the interrupts file contents
to decrease code duplication.

Felix Fietkau aebc0a88dd ath9k_hw: clean up ath9k_hw_setuprxdesc
The ATH9K_HW_CAP_AUTOSLEEP check is bogus, the rx status area needs to be
cleared on all non-EDMA PCI/AHB based chipsets anyway.
Limit the memset to the rx status area to improve performance.

Paul Gortmaker ee40fa0656 drivers/net: Add export.h to files using EXPORT_SYMBOL/THIS_MODULE
These were getting the macros from an implicit module.h
include via device.h, but we are planning to clean that up.

drivers/net: Add export.h to wireless/brcm80211/brcmfmac/bcmsdh.c

This relatively recently added file uses EXPORT_SYMBOL and hence
needs export.h included so that it is compatible with the module.h
split up work.

Felix Fietkau 2b63a41d14 ath9k_hw: add a new API for setting tx descriptors
Instead of using lots of different functions with long argument lists,
pull all the necessary information from one struct. This makes the code
easier to read and eliminates the need for copying data between multiple
linked descriptors.

Felix Fietkau 5519541d5a ath9k: fix powersave frame filtering/buffering in AP mode
This patch fixes a long standing issue of pending packets in the queue being
sent (and retransmitted many times) to sleeping stations.
This was made worse by aggregation through driver-internal retransmitting
of A-MDPU subframes.
Previously the hardware tx filter was cleared unconditionally for every
single packet - with this patch it uses the IEEE80211_TX_CTL_CLEAR_PS_FILT
for unaggregated frames.
A sta_notify driver op is added to stop aggregation for stations when they
enter powersave mode. Subframes stay buffered inside the driver, to ensure
that the BlockAck window keeps a sane state.
Since the driver uses software aggregation, the clearing of the tx filter
needs to be handled by the driver instead of mac80211 for aggregated frames.

Felix Fietkau ff32d9cd2c ath9k_hw: fix potential spurious tx error bit interpretation
According to documentation, AR_ExcessiveRetries, AR_Filtered and
AR_FIFOUnderrun are only valid if AR_FrmXmitOK is clear.

Not checking this might result in suboptimal FIFO settings, unnecessary
retransmissions, or other connectivity issues.

Felix Fietkau e0e9bc82fb ath9k_hw: optimize tx status descriptor processing
Disassembly shows, that at least on MIPS, the compiler generates a lot of
memory accesses to the same location in the descriptor field parsing.
Since it is operating on uncached memory, this can be quite expensive in
this hot path.
Change the code a bit to help the compiler optimize it properly, and get
rid of some unused fields in the ath_tx_status struct.

Felix Fietkau 45684c75f9 ath9k_hw: small optimization in ar9002_hw_get_isr
ah->config.rx_intr_mitigation does not need to be checked before checking
the rx interrupt mask for AR_ISR_RXMINTR or AR_ISR_RXINTM, as those
interrupts will be masked out if rx interrupt mitigation is disabled.

Avoid reading AR_ISR_S5_S twice by reordering the code to be more concise.
