starting from the one specified.
If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM. If it does, we read it and derive
the two subsequent addresses for WLAN.
During production, 3 addresses are reserved per device. The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.

The chunk size used during firmware upload was set to 512, which is
the size of a single SDIO block (or two). This is very inneficient
because we send one or two blocks only per SDIO transaction and don't
get the full benefits of sdio block transfers.
This patch increases the chunk size to 16K. This more than doubles
the transfer speed both in wl127x and wl128x chips, with greater
impact on the latter:
wl127x: 512 bytes chunk -> ~132ms
16384 bytes chunk -> ~57ms
wl128x: 512 bytes chunk -> ~216ms
16384 bytes chunk -> ~37ms
Signed-off-by: Luciano Coelho <coelho@ti.com>
The sdio driver uses a block size of 512 bytes by default. With our
card, this doesn't work correctly because it sets the block size FBR
in the chip too early (ie. before the chip is powered on). Thus, if
we don't set it explicitly, block mode remains disabled in the chip.
If we try to send more data than fits in one block, the sdio driver
will split it into separate blocks before sending to the chip. This
causes problems because the chip is not expecting multiple blocks.
At the moment this is not a problem, because we use chunks of 512
bytes for firmware upload and the data is always sent in byte mode.
In the next patch, we will change the chunk size to a bigger value, so
this patch is a preparation for that.

In order to fully abstract the bus, we need to save the device
structure *beside* wl1271, instead of inside it.
This will help re-structuring the driver so that we avoid the
duplicated code in the bus modules.

This module has been causing more trouble than being useful. It only
tests the SDIO speed by connecting to the wl12xx chip and does some
throughput calculations. It is an ugly quick hack and, if we really
want to have it as part of wl12xx we need to clean it up and implement
it properly.
A tarball of the code has been created and posted here, with some
instructions:

Currently, a single vif might starve all the other vifs.
Save the last vif we dequeued a packet from, and continue
with the following one using a round-robin policy.

add_interface might be called while the chip is
in elp. add elp_wakeup/sleep calls to handle it.

allocate the rate policies dynamically, instead of using hardcoded
indexes. this is needed for proper multi-role configuration.

The recovery work should call stop() after it removed
all the existing interfaces.

wl->vif is appropriate only when a single vif is being used.
Instead, pass wlvif as parameter or iterate through all
the vifs (e.g. when a global configuration was changed)
Leave wl->vif only to determine whether a vif was already
added (this check will be removed as well after both the
driver and fw will support multiple vifs)

When mac80211 changes a global (hw) config, iterate
through all the relevant vifs and update them.

move power_level into the per-interface data.
mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.
In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

move WL1271_FLAG_PSM and WL1271_FLAG_PSM_REQUESTED into
per-vif flags.
These flags should be set per-vif, rather than globally.
