After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list
headers showed up in the resulting cleanup fallout.  Give
them an explicit include via the following $0.02 script.

 =========================================
 #!/bin/bash
 MANUAL=""
 for i in `git grep -l 'prefetch(.*)' .` ; do
 	grep -q '&lt;linux/prefetch.h&gt;' $i
 	if [ $? = 0 ] ; then
 		continue
 	fi

 	(	echo '?^#include &lt;linux/?a'
 		echo '#include &lt;linux/prefetch.h&gt;'
 		echo .
 		echo w
 		echo q
 	) | ed -s $i &gt; /dev/null 2&gt;&amp;1
 	if [ $? != 0 ]; then
 		echo $i needs manual fixup
 		MANUAL="$i $MANUAL"
 	fi
 done

fresh skbs have ip_summed set to CHECKSUM_NONE (0)

We can avoid setting again skb-&gt;ip_summed to CHECKSUM_NONE in drivers.

Introduce skb_checksum_none_assert() helper so that we keep this
assertion documented in driver sources.

Change most occurrences of :

skb-&gt;ip_summed = CHECKSUM_NONE;

by :

skb_checksum_none_assert(skb);

<title>net: preserve ifreq parameter when calling generic phy_mii_ioctl().</title>

<id>28b041139e344ecd0f144d6205b004ae354cfa1e</id>
<content type='text'>
The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
We need access to the ifreq in order to support PHYs that can perform
hardware time stamping.

Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
This is unnecessary since phylib will check the command in any case.

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Drivers can avoid one cache miss
(on dev-&gt;trans_start) in their start_xmit() handler.

Exceptions are NETIF_F_LLTX drivers

mdiobus_register() calls device_register() which initializes the kobj of
the device. mdiobus_unregister() calls only device_del() so we have one
reference left. That one is leaving with mdiobus_free() which is only
called on remove.
Since I don't see any reason why mdiobus_register()/mdiobus_unregister()
should happen in -&gt;open()/-&gt;close() I move them to probe &amp; exit.
