On each TX descriptor allocation, a free entry is found by traversing the TX descriptors array. Improve this by holding a bitmap of all TX descriptors, and using efficient bit operations to search for free entries.

While wl1271_irq_work handles RX directly (by calling wl1271_rx), a different work is scheduled for transmitting packets. The IRQ work might handle more than one interrupt during a single call, including multiple TX completion interrupts. This might starve TX, since no packets are transmitted until all interrupts are handled. Fix this by calling the TX work function directly, instead of deferring it.

In case the aggregation buffer is too small to hold all available packets, the buffer is transferred to the FW and no more packets are aggregated. Although there may be enough available TX blocks, no additional packets will be handled by the current TX work. Fix this by flushing the aggregation buffer when it's full, and continue transferring packets as long as there are enough available TX blocks.

My previous patch to clean up all RXON handling inadvertently broke IBSS because it failed to take into account that unlike in AP mode, IBSS requires beacons to be sent only after setting the RXON assoc. Fix this, clean up the code a bit, improve the error checking around this, and also react to beacon changes in IBSS mode from mac80211.

In order to simplify the flow, and make new enhancements easier, separate out the RXON processing for modern AGN (5000 and newer) from RXON processing for the older 3945 and 4965 devices. Avoid changing these old ones to avoid regressions and move their code to a new file (iwl-legacy.c). 4965 gets the commit_rxon that used to be common for all AGN devices, but with removed PAN support. The new RXON processing is more central and does more work in committing, so that it is easier to follow. To make it more evident what is split out for legacy, split the necessary operations for that into a new struct iwl_legacy_ops. Those parts that still exist in the new AGN code don't need to be parametrized.

This helps align resets / RX enable & disable / TX stop / start. Locking around the PCU is important to ensure the hardware doesn't get stale data when working with DMA'able data. This is part of a series of patches which fix stopping TX DMA completley when requested on the driver.

Almost anywhere in the code we avoid committing rxon while performing scan, and make rxon commit when scan complete. However in some places in the code we do not follow that rule. This patch fix that problem in iwlagn_configure_filter(). Since we do not commit directly in iwl3945_configure_filter, we can also do the same for agn, so I just remove iwlcore_commit_rxon() function and add a comment. Also change comment for iwl3945.

We have seen several DMA races when we race against stopping and starting the PCU. I suspect that when we cannot stop the PCU we may hit some of these same races so warn against them for now but only when debugging (CONFIG_ATH_DEBUG) is enabled. If you run into this warning and are a developer, please fix the cause of the warning. The potential here, although I cannot prove yet, is that the DMA engine can be confused and start writing to a buffer that was already DMA'd before and at least the kernel assumes is not being accessed by hardware anymore.

To be used to throw out warnings only for developers.
