Commit 5c33d9b2 authored by Linus Torvalds's avatar Linus Torvalds

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.

* We also adjust for any unused space in the main
* data area by subtracting (RX_COPY_THRESHOLD -
* len). This is especially important with drivers
* which split incoming packets into header and data,
* using only 66 bytes of the main data area (see the
* e1000 driver for example.) On such systems,
* without this last adjustement, our achievable
* receive throughout using the standard receive
* buffer size was cut by 25%(!!!).
