e00adf3913 drivers/net: rename random32() to prandom_u32()
Use preferable function name which implies using a pseudo-random number
generator.

80d5c3689b net: vlan: prepare for 802.1ad VLAN filtering offload
Change the rx_{add,kill}_vid callbacks to take a protocol argument in
preparation of 802.1ad support. The protocol argument used so far is
always htons(ETH_P_8021Q).

f646968f8f net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*
Rename the hardware VLAN acceleration features to include "CTAG" to indicate
that they only support CTAGs. Follow up patches will introduce 802.1ad
server provider tagging (STAGs) and require the distinction for hardware not
supporting acclerating both.

72b270323d team: Use new sync_multiple api to sync devices adressess.
Team drivers attempts to sync addresses to each of the port
devices; however, the current api doesn't really perform the sync
for any device after the first one.  Switch to using the new api
that will actually sync the addresses to all ports.

Pull driver core patches from Greg Kroah-Hartman:
 "Here is the big driver core merge for 3.9-rc1

  There are two major series here, both of which touch lots of drivers
  all over the kernel, and will cause you some merge conflicts:

   - add a new function called devm_ioremap_resource() to properly be
     able to check return values.

   - remove CONFIG_EXPERIMENTAL

  Other than those patches, there's not much here, some minor fixes and
  updates"

e185483e6b team: allow userspace to take control over carrier
Some modes don't require any special carrier handling so
in these cases, the kernel can control the carrier as for
any other interface.  However, some other modes, e.g. lacp,
requires more than just that, so userspace needs to control
the carrier itself.

The daemon today is ready to control it, but the kernel
still can change it based on events.

This fix so that either kernel or userspace is controlling
the carrier.

b3c581d5d7 team: set qdisc_tx_busylock to avoid LOCKDEP splat
If a qdisc is installed on a team device, its possible to get
a lockdep splat under stress, because nested dev_queue_xmit() can
lock busylock a second time (on a different device, so its a false
positive)

Avoid this problem using a distinct lock_class_key for team
devices.
