rtnetlink: support specifying device flags on device creation
commit
e8469ed959c373c2ff9e6f488aa5a14971aebe1f
Author: Patrick McHardy <kaber@trash.net>
Date: Tue Feb 23 20:41:30 2010 +0100
Support specifying the initial device flags when creating a device though
rtnl_link. Devices allocated by rtnl_create_link() are marked as INITIALIZING
in order to surpress netlink registration notifications. To complete setup,
rtnl_configure_link() must be called, which performs the device flag changes
and invokes the deferred notifiers if everything went well.
Two examples:
# add macvlan to eth0
#
$ ip link add link eth0 up allmulticast on type macvlan

dev: support deferring device flag change notifications
Split dev_change_flags() into two functions: __dev_change_flags() to
perform the actual changes and __dev_notify_flags() to invoke netdevice
notifiers. This will be used by rtnl_link to defer netlink notifications
until the device has been fully configured.
This changes ordering of some operations, in particular:
- netlink notifications are sent after all changes have been performed.
As a side effect this surpresses one unnecessary netlink message when
the IFF_UP and other flags are changed simultaneously.
- The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked
after all changes have been performed. Their relative is unchanged.
- net_dmaengine_put() is invoked before the NETDEV_DOWN notifier instead
of afterwards. This should not make any difference since both RX and TX
are already shut down at this point.

when TSO is disabled netif_tx_stop_all_queues is called. If the watchdog
timer fires while the queues are stopped and traffic has not recently been
sent on a paticular queue this is falsly identified as a hang and
ndo_tx_timeout() is called. This is ocossionally seen during testing.
This removes the netif_tx_stop_all_queues() it is not needed. The scheduler
submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and
if so it calls dev_gso_segment. Disabling TSO will cause dev_hard_start_xmit()
to do the gso processing. However ixgbe does not use the features flags to
determine if it needs to use tso or not instead it uses skb->gso_size so
ixgbe will process these frames correctly regardless of the netdev features
flag.

ixgbe: Fix DMA mapping/unmapping issues when HWRSC is enabled on IOMMU enabled kernels
Work around 82599 HW issue when HWRSC is enabled on IOMMU enabled
kernels. 82599 HW is updating the header information after setting the
descriptor to done, resulting DMA mapping/unmapping issues on IOMMU
enabled systems. To work around the issue delay unmapping of first packet
that carries the header information until end of packet is reached.

isa-skelton: Remove a wrong netif_wake_queue() call
The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from net_tx(). So Unconditional call to the
netif_wake_queue() here is wrong. This might cause calling of
start_xmit routine on txfull state and trigger tx-ring overflow.
This fix is ported from commit
662a96bd6f020782dfbdc0d0bd177c7dbb556687

This patch makes the bus-error reporting configurable and allows to
retrieve the CAN TX and RX bus error counters via netlink interface.
I have added support for the SJA1000. The TX and RX bus error counters
are also copied to the data fields 6..7 of error messages when state
