b44: Disable device on shutdown

2009-02-27T06:35:02+00:00

Disable the SSB core on device shutdown.
This has two advantages:
1) A clean device shutdown is always desired here, because we disable
  the device's global crystal in the next statement.
2) This fixes a bug where the device will come up with the enable-bit
  set on the next initialization (without a reboot inbetween).
  This causes breakage on the second initialization due to code that
  checks this bit (ssb_device_is_enabled() checks).

b44: Unconditionally enable interrupt routing on reset

2009-02-27T06:33:00+00:00

Unconditionally setup the IRQ routing on chip reset.
It's safe to call ssb_pcicore_dev_irqvecs_enable() unconditionally, because
it has internal checks for redundant calls.

This fixes problems where hardware will not come up properly
due to quirks in the enable-bit hardware.

b44: GFP_DMA skb should not escape from driver

2009-01-15T23:29:35+00:00

b44 chip has some hardware limitations, that need GFP_DMA bounce
buffers in some situations.

In order to not deplete DMA zone, we should keep allocated GFP_DMA skb
only for driver use. At rx time, we copy such skb to newly allocated
skb, reusing existing copybreak infrastructure.

On machines with low amount of memory, all skb meet the hardware limitation,
so no copy is needed. We detect this situation using a new device flag, set
to one if one GFP_DMA skb was ever allocated by b44_alloc_rx_skb().

Previously allocated skb, even outside from DMA zone will then be recycled,
to have minimal impact on DMA zone use.

b44: fix misalignment and wasted space in rx handling

2009-01-11T08:04:12+00:00

Broadcom 4400 puts a header of configurable size (apparently needs
to be at least 28 bytes) in front of received packets. When handling
this, the previous code accidentally added the offset 30 *twice* for
the software and once for the hardware, thereby cancelling out the
IP alignment effect of the 30 byte padding and wasting an additional
30 bytes of memory per packet.

This patch fixes this problem and improves routing throughput by
about 30% on MIPS, where unaligned access is expensive.

net: Fix warning fallout from recent NAPI interface changes.

2008-12-26T23:10:00+00:00

When we removed the network device argument from several
NAPI interfaces in 908a7a16b852ffd618a9127be8d62432182d81b4
("net: Remove unused netdev arg from some NAPI interfaces.")
several drivers now started getting unused variable warnings.

This fixes those up.

net: Remove unused netdev arg from some NAPI interfaces.

2008-12-23T04:43:12+00:00

When the napi api was changed to separate its 1:1 binding to the net_device
struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
vestigual net_device structure parameter.  This patch cleans up that api by
properly removing it..

drivers/net: Kill now superfluous ->last_rx stores.

2008-11-04T05:11:17+00:00

The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

net: convert print_mac to %pM

2008-10-28T00:06:18+00:00

This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

ssb, b43, b43legacy, b44: Rewrite SSB DMA API

2008-06-27T13:09:15+00:00

This is a rewrite of the DMA API for SSB devices.
This is needed, because the old (non-existing) "API" made too many bad
assumptions on the API of the host-bus (PCI).
This introduces an almost complete SSB-DMA-API that maps to the lowlevel
bus-API based on the bustype.
