Linus Torvalds 5c33d9b248 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:

 1) New sysctl ndisc_notify needs some documentation, from Hanns
    Frederic Sowa.

 2) Netfilter REJECT target doesn't set transport header of SKB
    correctly, from Mukund Jampala.

 3) Forcedeth driver needs to check for DMA mapping failures, from Larry
    Finger.

 4) brcmsmac driver can't use usleep_range while holding locks, use
    udelay instead.  From Niels Ole Salscheider.

 5) Fix unregister of netlink bridge multicast database handlers, from
    Vlad Yasevich and Rami Rosen.

 6) Fix checksum calculations in netfilter's ipv6 network prefix
    translation module.

 7) Fix high order page allocation failures in netfilter xt_recent, from
    Eric Dumazet.

 8) mac802154 needs to use netif_rx_ni() instead of netif_rx() because
    mac802154_process_data() can execute in process rather than
    interrupt context.  From Alexander Aring.

 9) Fix splice handling of MSG_SENDPAGE_NOTLAST, otherwise we elide one
    tcp_push() too many.  From Eric Dumazet and Willy Tarreau.

10) Fix skb->truesize tracking in XEN netfront driver, from Ian
    Campbell.

TODO bcma: add Broadcom specific AMBA bus driver 2011-05-10 15:54:54 -04:00

Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
however from programming point of view there is nothing AMBA specific we use.

Standard AMBA drivers are platform specific, have hardcoded addresses and use
AMBA standard fields like CID and PID.

In case of Broadcom's cards every device consists of:
1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
   as standard AMBA device. Reading it's CID or PID can cause machine lockup.
2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
   and PIDs (0x103BB369), but we do not use that info for anything. One of that
   devices is used for managing Broadcom specific core.

Addresses of AMBA devices are not hardcoded in driver and have to be read from
EPROM.

In this situation we decided to introduce separated bus. It can contain up to
16 devices identified by Broadcom specific fields: manufacturer, id, revision
and class.
