we must be able to roll back device registration in case setting the
flags fails without sending any notifications related to the device

This patch changes rollback_registered_many() and register_netdevice()

rtnl_link and allows to defer notifications for devices handled by

b44: Set PHY address to NO_PHY if reset fails.
Do a PHY reset to test if there is an active phy and set the PHY address
to B44_PHY_ADDR_NO_PHY in case of an not active phy. This is needed for
the Linksys WRTSL54GS and Asus WL-500W.
This patch was used in OpenWRT for a long time.

ixgbe: prevent speculative processing of descriptors before ready
The PowerPC architecture does not require loads to independent bytes to be
ordered without adding an explicit barrier.
In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.
The problem occurs with packet split enabled where the TCP/IP header and data
are in different descriptors. If the reads go out of order we may have data
that doesn't match the TCP/IP header. Since we use hardware checksumming this
bad data is never verified and it makes it all the way to the application.
This bug was found during stress testing and adding this barrier has been shown
to fix it.

mwl8k: convert to new station add/remove callbacks
This converts mwl8k to use the new station
add/remove callbacks instead of using the
old sta_notify callback.
The new callbacks can sleep, so a lot of
code can be removed now.

iwlwifi: sanity check before counting number of tfds can be free
Check the frame control for ieee80211_is_data_qos() is true before
counting the number of tfds can be free, the tfds_in_queue only
increment when ieee80211_is_data_qos() is true before transmit; so it
should only decrement if the type match.
Remove ieee80211_is_data_qos check for frame_ctrl in tx_resp to avoid
invalid information pass from uCode.
