Previously, we had a fixed array of 5 elements where we remembered all
initialized devices. This has been changed to use a "struct list_head"
organization, which is IMHO cleaner.
Also renamed usb_cardp to cardp, as in the reset of the code.
Renamed reset_device() to if_usb_reset_device() like many other functions.

use a different default FW name than the CF module, so libertas_fw_name
is now local to if_usb.c

Split wlan_add_card() into a part that just setups kernel parameters and
into the function libertas_activate_card(), which will implizitly use
hardware functions by the started thread.
This allows us later to do something like this:
priv = libertas_add_card();
priv->hw_command_to_host = if_usb_command_to_host;
priv->hw_xxxx = if_usb_xxxx;
priv->hw_yyyy = if_usb_yyyy;
wlan_activate_card()
and of course the CF driver can set it's own functions.

This gives time to the firmware so it can go back to the association

This did corrupt register s0 which the caller of self_ipi expects to

This must be the oldest bug that we have got. Leaving interrupts "as
they are" for the R3000 obviously means copying IEp to IEc. Since we have
got STATMASK now, I took this opportunity to mask the status register
"correctly" for the R3000 now too. Oh, and the R3000 hardly ever is
64-bit.

After SRST, libata used to wait for nsect/lbal to be set to 1/1 for
the slave device. However, some ATAPI devices don't set nsect/lbal
after SRST and the wait itself isn't too useful as we're gonna wait
for !BSY right after that anyway.
Before reset-seq update, nsect/lbal wait failure used to be ignored
and caused 30sec delay during detection. After reset-seq, all
timeouts are considered error conditions making libata fail to detect
such ATAPI devices.
This patch limits nsect/lbal wait to around 100ms. This should give
acceptable behavior to such ATAPI devices while not disturbing the
heavily used code path too much.

The ata IRQ ack functions are only used when debugging. Unfortunately
almost every controller that calls them can cause crashes in some
configurations as there are missing checks for bmdma presence.
In addition ata_port_start insists of installing DMA buffers and pad
buffers for controllers regardless. The SFF controllers actually need to
make that decision dynamically at controller setup time and all need the
same helper - so we add ata_sff_port_start. Future patches will switch
the SFF drivers to use this.
