The combination of r35942 and r35952 causes an issue where eth_schedule_poll()
can be called from a different CPU between the call to napi_complete() and the
setting of cur_index which can break the rx ring accounting and cause ethernet
latency and/or ethernet stalls. The issue can be easilly created by adding
a couple of artificial delays such as:

This patch moves the setting of cur_index back up where it needs to be and
addresses the original corner case that r35942 was trying to catch in an
improved fashion by checking to see if the rx descriptor ring has become
full before interrupts were re-enabled so that a poll can be scheduled again
and avoid an rx stall caused by rx interrupts ceasing to fire again.

The IMX6 SoC uses an ARM Cortext-A9 which has both NEON and VFPv3 hardware
blocks. This will tune gcc to use neon instead of vfpv3 which will outperform
VFPv3.

The OpenWrt build system uses MACHINE_FEATURES of fpu to set the HAS_FPU which
in turn sets the default of CONFIG_SOFT_FLOAT as well as uClibc configuration.
As the IMX6 SoC has both vfpv3 and NEON hardware support we want to add fpu
to the feature list. This will default the IMX6 target to use -mfloat-abi=hard
which will the be most efficient use of floating point.
When switching to hard float, we also need to enable VFP support in the kernel.

launched by QEMU or a real bootloader, use zImage-initramfs instead.

The ar71xx platform always uses the eth0 interface to provide
access to the device in failsafe mode. Due to this, failsafe
access is broken on devices where the LAN ports are connected
to the 'eth1' interface.
Update the relevant script to correctly set the ifname variable
for these devices.

Similarly to the previously broken address pools, DNS-servers and some
MSRs could be advertised incorrectly as well. This is now fixed.

If a package directly depends on another package that recently changed
its ABI version, it will be cleaned up and rebuilt (assuming quilt is
not used).
This helps with packages that have no stable ABI, e.g. libubox, ubus,
etc.

We did not start the PHY when an external phy was in use. Without this
patch the driver uses half duplex mode and the switch uses full duplex
mode, which causes problems.
