The timer callback, fib6_run_gc, is actually used to be called
synchronously by some functions and asynchronously when the timer
expires.
When the timer expires, the delay specified for fib6_run_gc parameter
is always zero. So, I changed fib6_run_gc to not be a timer callback
but a function called by the timer callback and I added a timer
callback where its work is just to retrieve from the data arg of the

rt2x00: Add queue statistics to debugfs
Rename "frame" folder to "queue" folder,
add extra file to this folder which contains
statistics about all hardware queues. This will
help debugging and spotting problems in the
queue indexing system.

rt2x00: Fix scheduling while atomic errors in usb drivers
Call rt2x00_config_intf() outside of the spinlock context since
the call will sleep for USB drivers. By using the ieee80211_if_conf
values as arguments we make keep access tp rt2x00_intf thread safe
even without the lock.

rt2x00: make csr_cache and csr_addr an union
The csr_cache and csr_addr pointers are both the same size
and they are never used both by the same driver. This makes
them a nice candidate for an union.
We could merge into 1 pointer, but that would either upset sparse,
or require a lot of __force casts.

rt2x00: correct address calc for queue private data
When calculating the offset to add to the queue entry base to get the
individual entry's private data area the base address must be treated
as a char * not a struct queue_entry so we can do byte oriented
pointer arithmetic with it.

rt2x00: Make rt2x00 less verbose
Remove the debug messages regarding initialization from
EEPROM. The values are vendor specific, and are not really
needed for debug purposes. If they ever become usefull we
still have access to them through debugfs which also
prints the exact same values...

rt2x00: Fix invalid DMA free
Be more strict when using the queue_entry_priv_pci_rx
and queue_entry_priv_pci_tx structures. Only use a
particular type that matches the queue type.
When freeing the DMA the priv_tx->data and priv_tx->dma
was used. This is incorrect since the start of the DMA
was in fact the priv_tx->desc pointer. Instead of
recalculating the dma_addr_t for the DMA start this
patch will swap the data and descriptor part of the
allocated memory.
