Subject: [PATCH net-next V2 0/8] net: fec: cleanup/fixes


V2 is a rebase on top of johannes endian-safe patch and
is only the 1st eight patches.
The testing for this series was done on a nitrogen6x.
The base commit was
commit b45efa30a626e915192a6c548cd8642379cd47cc
    Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Testing showed no change in performance.
Testing used imx_v6_v7_defconfig + CONFIG_MICREL_PHY.
The processor was running at 996Mhz.
The following commands were used to get the transfer rates.

On an x86 ubunto system,
iperf -s -i.5 -u


On a nitrogen6x board, running via SD Card.
I first stopped some background processes

stop cron
stop upstart-file-bridge
stop upstart-socket-bridge
stop upstart-udev-bridge
stop rsyslog
stop dbus
killall dhclient
echo performance >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

taskset 0x2 iperf -c 192.168.0.201 -u -t60 -b500M -r

There is a branch available on github with this series, and the rest of
my fec patches, for those who would like to test it.
https://github.com:boundarydevices/linux-imx6.git branch net-next_master
