Subject: [PATCH] drivers/net/arcnet/: possible cleanups

This patch contains the following possible cleanups:
- make needlessly global code static
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arc_proto_null)
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arcnet_dump_packet)

To make Jeff happy, arcnet.c still prints
  arcnet: v3.93 BETA 2000/04/29 - by Avery Pennarun et al.

Subject: [PATCH] mv643xx_eth: use MII library for ethtool functions

Use the common ethtool support functions of the MII library.
Add generic MII ioctl handler.
Add PHY parameter speed/duplex/negotiation initialization and modification.

Subject: [PATCH] mv643xx_eth: Clean up platform_data configuration

We shouldn't expose the hardware register contents in platform_data.
The only things we allow the user to configure are autoneg, speed, and
duplex.  Add specific platform_data fields for these values and remove
the registers configs.

Subject: [PATCH] ieee80211: Add TKIP crypt->build_iv

This patch adds ieee80211 TKIP build_iv() method to support hardwares
that can do TKIP encryption but relies on ieee80211 layer to build
the IV. It also changes the build_iv() interface to return the key
if possible after the IV is built (this is required by TKIP).

Subject: [PATCH] ieee80211: common wx auth code

This patch creates two functions ieee80211_wx_set_auth and
ieee80211_wx_get_auth that can be used by drivers for the wireless
extension handlers instead of writing their own, if the implementation
should be software only.

These patches enable using bcm43xx devices with WPA and this seems (as
far as I can tell) to be the only difference between the stock ieee80211
and softmac's ieee80211 left.

The current bonding driver receives duplicate packets when broadcast/
multicast packets are sent by other devices or packets are flooded by the
switch. In this patch, new flags are added in priv_flags of net_device
structure to let the bonding driver discard duplicate packets in
dev.c:skb_bond().

	Modified by Jay Vosburgh to change a define name, update some
comments, rearrange the new skb_bond() for clarity, clear all bonding
priv_flags on slave release, and update the driver version.
