There is no need to call ether_setup after alloc_ethdev since it was
already called there.
Follow commits c706471b2601 ("net: axienet: remove unnecessary
ether_setup after alloc_etherdev") and 3c87dcbfb36c ("net: ll_temac:
Remove unnecessary ether_setup after alloc_etherdev") and fix the
pattern in all remaining ethernet drivers.

If netdev_alloc_skb_ip_align() fails, subsequent code will
try to dereference an invalid pointer.
Continue to next descriptor on error.
While we're at it,
1. eliminate the chance of an endless loop, replace the main
loop with while(rx < budget)
2. use napi_complete() and remove the explicit napi_gro_flush()

DMA memory should be synchronized before data is passed
to/from controller.
Add dma_sync_single_for_cpu(.., DMA_FROM_DEVICE) to RX path
and dma_sync_single_for_device(.., DMA_TO_DEVICE) to TX path.

build_skb() is used to make skbs out of existing RX ring memory
which is bad because the RX ring is allocated only once, on probe.
Memory corruption occur because said memory is reclaimed, i.e.
__kfree_skb() (and eventually put_page()).
Replace build_skb() with netdev_alloc_skb_ip_align() and use memcpy().
Remove SKB_DATA_ALIGN() from RX buffer size while we're at it.

TX buffer length is not cleared on ndo_start_xmit().
Failing to do so can bug/hang the controller and
cause TX interrupts to stop altogether.
Remove the readl() and compute a new value for DESC1.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
This covers everything under drivers/net except for wireless, which
has been submitted separately.

Reported by "make includecheck"
Tested that drivers/net/ethernet/moxa/moxart_ether.c still compiles
well on ARM

This patch fix the error handling in moxart_mac_probe():
- return -ENOMEM in some memory alloc fail cases
- add missing free_netdev() in the error handling case

__initdata tag should be placed between the variable name and equal
sign for the variable to be placed in the intended .init.data section.
In this particular case __initdata is incorrect as moxart_mac_driver
can be used after the driver gets initialized.
Also while at it static-ize moxart_mac_driver.

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

The MOXA UC-711X hardware(s) has an ethernet controller that seem
to be developed internally. The IC used is "RTL8201CP".
Since there is no public documentation, this driver is mostly the
one published by MOXA that has been heavily cleaned up / ported
from linux 2.6.9.
