136492b275 EMAC driver: add power down mode
This patch puts phy in power-down mode when interface is down.
Also we should think about energy detect power-down mode, that will
decrease power consumption when no link.

775919bc23 EMAC driver: bf537 MAC multicast hash filtering patch
The bf537 Ethernet MAC driver in the 2007R1.1-RC3 kernel (and the
current kernel) do not implement multicast hash filtering. This
is a performance problem if you have lots of multicast on your network.

This patch plugs the right bits into the multicast hash registers.

00ff49a91e Blackfin EMAC driver: fix bug - NAT doesn't work with bfin_mac driver
https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&forum_id=39&thread_id=23114&_forum_action=ForumMessageBrowse
Today I was dealing with the same problem, on my custom bf537 board, and bfin_mac driver.
I found that the problem is in setting ip_summed flag of skbuff structure,

73f8318286 Blackfin EMAC driver: add function to change the MAC address
Alex Landau writes in the forums:
 Previously, changing the MAC address (e.g. via ifconfig) resulted
 in a generic function to be called that only changed a variable in
 memory. This patch also updated the Blackfin MAC address registers
 to filter the correct new MAC.

09f75cd7bf [NET] drivers/net: statistics cleanup #1 -- save memory and shrink code
We now have struct net_device_stats embedded in struct net_device,
and the default ->get_stats() hook does the obvious thing for us.

Run through drivers/net/* and remove the driver-local storage of
statistics, and driver-local ->get_stats() hook where applicable.

This was just the low-hanging fruit in drivers/net; plenty more drivers
remain to be updated.

10d024c1b2 [NET]: Nuke SET_MODULE_OWNER macro.
It's been a useless no-op for long enough in 2.6 so I figured it's time to
remove it.  The number of people that could object because they're
maintaining unified 2.4 and 2.6 drivers is probably rather small.
