908a7a16b8 net: Remove unused netdev arg from some NAPI interfaces.
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..

008298231a netdev: add more functions to netdevice ops
This patch moves neigh_setup and hard_start_xmit into the network device ops
structure. For bisection, fix all the previously converted drivers as well.
Bonding driver took the biggest hit on this.

Added a prefetch of the hard_start_xmit in the fast path to try and reduce
any impact this would have.

4cf1653aa9 netdevice: safe convert to netdev_priv() #part-2
We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.
But it is too big to be sent in one mail.
I split it to 4 parts and make every part smaller than 100,000 bytes,
which is max size allowed by vger.

babcda74e9 drivers/net: Kill now superfluous ->last_rx stores.
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.

3ed30676f5 e1000: don't generate bad checksums for tcp packets with 0 csum
When offloading transmit checksums only, the driver was not
correctly configuring the hardware to handle the case of a zero
checksum.  For UDP the correct behavior is to leave it alone, but
for tcp the checksum must be changed from 0x0000 to 0xFFFF.  The
hardware takes care of this case but only if it is told the
packet is tcp.

Here's the patch. It shrinks the stack from 1152 bytes to 192 bytes (the

b45f87681e e1000: remove e1000_clean_tx_irq call from e1000_netpoll
The call to e1000_clean_tx_irq in e1000_netpoll can race with the call
to e1000_clean_tx_irq in e1000_clean.  With a small bit of tweaking to
to netpoll_send_skb to simulate a system that was under extreme stress,
I was able to reproduce these concurrent calls.  This can result in
multiple frees to the skbs on the tx ring buffer.

Dropping this call from e1000_netpoll should be fine since we can rely
on the calls in e1000_clean to do what is needed since napi will poll
the hardware just after calling poll_controller.

3c34ac36ac e1000: Fix for 32 bits platforms with 64 bits resources
The e1000 driver stores the content of the PCI resources into
unsigned long's before ioremapping. This breaks on 32 bits
platforms that support 64 bits MMIO resources such as ppc 44x.

This fixes it by removing those temporary variables and passing
directly the result of pci_resource_start/len to ioremap.

The side effect is that I removed the assignments to the netdev
fields mem_start, mem_end and base_addr, which are totally useless
for PCI devices.

60e233172e [net] Gracefully handle shared e1000/1000e driver PCI ID's
Both the old e1000 driver and the new e1000e driver can drive some
PCI-Express e1000 cards, and we should avoid ambiguity about which
driver will pick up the support for those cards when both drivers are
enabled.

This solves the problem by having the old driver support those cards if
the new driver isn't configured, but otherwise ceding support for PCI
Express versions of the e1000 chipset to the newer driver.  Thus
allowing both legacy configurations where only the old driver is active
(and handles all chips it knows about) and the new configuration with
the new driver handling the more modern PCIE variants.

db0ce50d37 [E1000]: Secondary unicast address support
Add support for configuring secondary unicast addresses. Unicast
addresses take precendece over multicast addresses when filling
the exact address filters to avoid going to promiscous mode.
When more unicast addresses are present than filter slots,
unicast filtering is disabled and all slots can be used for
multicast addresses.
