Enable LED by default and update the MODULE_PARM_DESC. The original
reason for defaulting to disabled was documented in 2005 and noted, "The
LED code has been reported to hang some systems when running ifconfig
and is therefore disabled by default." This no longer appears
applicable and users have been requesting this be enabled for several
years.

SKBs hold onto resources that can't be held indefinitely, such as TCP
socket references and netfilter conntrack state. So if a packet is left
in TX ring for a long time, there might be a TCP socket that cannot be
closed and freed up.
Current blackfin EMAC driver always reclaim and free used tx skbs in future
transfers. The problem is that future transfer may not come as soon as
possible. This patch start a timer after transfer to reclaim and free skb.
There is nearly no performance drop with this patch.
TX interrupt is not enabled because of a strange behavior of the Blackfin EMAC.
If EMAC TX transfer control is turned on, endless TX interrupts are triggered
no matter if TX DMA is enabled or not. Since DMA walks down the ring automatically,
TX transfer control can't be turned off in the middle. The only way is to disable
TX interrupt completely.

Explicitly enable the usage of fallback rates for
the transmission of frames with rt61pci and rt73usb hardware.
Note that for txdone reporting, only rt61pci is capable of
reporting the fallback rates, for USB it is not possible
to determine the number of retries. However the device will
use the fallback rates, so it might still help in the performance.

In some corner cases the reported tx rates/retries didn't match the really
used ones.
The hardware lowers the tx rate on each consecutive retry by 1 (but won't
fall back from MCS to legacy rates) _until_ it reaches the lowest one.
In case the frame wasn't sent succesful the number of retries is 7 and if
a rate index <7 was used the previous code reported negative rate indexes
which were then ignored by the rate control algorithm and mac80211.
Instead, report the remaining number of retries to have happened with
the lowest rate (index 0). This should give the rate control algorithm
slightly more accurate information about the used tx rates/retries.

Set up max_rates and max_rate_tries with suitable values even if we do not
support the whole functionality.
As rt2800 has a global fallback table we cannot specify more then one tx rate
per frame but since the hw will try several different rates (based on the
fallback table) we should still initialize max_rates to the maximum number of
rates we are going to try. Otherwise mac80211 will truncate our reported tx
rates and the rc algortihm will end up with incorrect data choosing unsuitable
rates for tx.
This improves throughput on rt2800 devices considerable.

Currently rt2800pci will read TX_STA_FIFO until the previously read value
matches the current value. However, it is obvious that TX_STA_FIFO only
contains values that can easily be the same for multiple consecutive frames
(especially when communicating with only one other STA). Hence, we often
ended up with reading only the first entry and ignoring the rest.
One result was that when the TX_STA_FIFO contained multiple entires, only
the first one was read and properly handled while the others remained in the
tx queue.
Thus, drop this check but introduce a maximum number of reads. All legacy
drivers use the size of the tx ring as limit but state that the TX_STA_FIFO
has only 16 entries. So, let's just stick with the tx ring size for now.

TXDONE_FALLBACK doesn't express if the frame was sent successful or not. It
only tells us that the hw used fallback rates for retries. Hence, don't use
TXDONE_FALLBACK as success indicator.
Before this patch we reported success to the rate control algorithm which
was wrong in a number of cases and might have lead to improper tx rate
selections.
