Gabor Juhos 624cfc5c91 ramips: DMA map the correct RX skb size
The skb_reserve call prior to DMA mapping the RX skb reduced the skb
data len by 2. To not allow DMA to write behind the skb we should pass
the correct skb data len to the device.

Gabor Juhos 69355ee10e ramips: Allow ethernet interface to be taken down and up again
Taking the ramips ethernet interface down and up again resulted in the
driver not receiving any frames anymore. Fix this by correctly disabling
interrupts in the hw on ifdown.

Gabor Juhos e5b081335e ramips: Ralink RT305x, support for Prolink PWH2004 (Abocom5205)
The attached patch adds a preliminary support for Prolink PWH2004 board
(Ralink RT305x based). LAN and flash appear to work. However, the USB
port and WLAN I have not managed to activate properly yet, but that
problem appears to be present with other rt305x targets as well(?).

Gabor Juhos 462dabc7f5 ramips: add support for Sparklan WCR-150GN board
This patch adds support for Sparklan WCR-150GN board.
Network configuration should be tweaked to make it work fully. The
reason it's not in this patch is that ramips target should be modified
to support different /etc/config/network files for different boards.

Gabor Juhos d14e9e706e ramips: Fix bridging in ramips ethernet driver
Bridging between the ramips ethernet driver and rt2800pci was somewhat
broken. Frames received by the ethernet driver which were passed to the
wifi driver for transmission were sometimes corrupted or sent out with
huge delays.

The reason for this is the missing assignment of skb->tail in the ramips
ethernet driver's rx path resulting in skb->tail pointing to skb->data.
Since skb->tail is used by mac80211 it writes into skb->data which messes
up the frames content.

Fix this by using skb_put to correctly set skb->len and skb->tail.
