Almost all of these have long outstayed their welcome.

And for every one of these macros, there are 10 features for which we
didn't add macros.

Let's just delete them all, and get out of habit of doing things this
way.

Make sure that the 'static' keywork is at the beginning of declaration

This gets rid of warnings like

when building with -Wold-style-declaration (and/or -Wextra which also
enables it).

And mask the hash function result by simply shifting
down the "->hash_shift" most significant bits.

Currently which bits we use is arbitrary since jhash
produces entropy evenly across the whole hash function
result.

But soon we'll be using universal hashing functions,
and in those cases more entropy exists in the higher
bits than the lower bits, because they use multiplies.

This is a backport from the vendor driver of support for the newer Optima
(Prime and 2) chipsets. It also includes some setup changes for the
current Optima chip as well. The code and comments intentionally
mirror the vendor sk98lin driver to allow for easier maintenance.

Although this adds support for new chip id's, these chip id's are not
used by any of the current PCI device id's listed in the driver.
The patch is just to get initial infrastructure in place to handle them
when they come.

I don't have access to any of this hardware to actually test it yet.

Implementing this callback function will cause mac80211 refrain from
going to powersave state when there are still untransmitted TX frames
in the queues.
This would exactly mimic the behaviour of the legacy vendor driver which
also doesn't go in powersave mode if there are still TX frames that are not
transmitted.
This should make powersaving and rt2x00 a better couple.

The functions that create the tx descriptor structure do not operate on
a queue entry at all. Signal this fact in the code by not providing a
queue entry as a parameter, but the rt2x00 device structure and the skb
directly.

a tx operation.

The rt2x00 driver gets frequent occurrences of the following error message
when operating under load:
phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the
non-full queue 2.

This is caused by simultaneous attempts from mac80211 to send a frame via
rt2x00, which are not properly serialized inside rt2x00queue_write_tx_frame,
causing the second frame to fail sending with the above mentioned error
message.

Fix this by introducing a per-queue spinlock to serialize the TX operations
on that queue.

To keep transtable consistency among all the nodes, an originator must

Instead, deleted client have to be kept in the table in order to be sent

network will always provide the same response for the same request.
