This reverts commits 61e00655, 73f8645d and 8e22ecb6:
  "Input: introduce BTN/ABS bits for drums and guitars"
  "HID: wiimote: add support for Guitar-Hero drums"
  "HID: wiimote: add support for Guitar-Hero guitars"

The extra new ABS_xx values resulted in ABS_MAX no longer being a
power-of-two, which broke the comparison logic.  It also caused the
ioctl numbers to overflow into the next byte, causing problems for that.

We'll try again for 3.13.

This commit fixes a long-standing bug that has been reported by many
users: on some Armada 370 platforms, only the network interface that
has been used in U-Boot to tftp the kernel works properly in
Linux. The other network interfaces can see a 'link up', but are
unable to transmit data. The reports were generally made on the Armada
370-based Mirabox, but have also been given on the Armada 370-RD
board.

The network MAC in the Armada 370/XP (supported by the mvneta driver
in Linux) has a functionality that allows it to continuously poll the
PHY and directly update the MAC configuration accordingly (speed,
duplex, etc.). The very first versions of the driver submitted for
review were using this hardware mechanism, but due to this, the driver
was not integrated with the kernel phylib. Following reviews, the
driver was changed to use the phylib, and therefore a software based
polling. In software based polling, Linux regularly talks to the PHY
over the MDIO bus, and sees if the link status has changed. If it's
the case then the adjust_link() callback of the driver is called to
update the MAC configuration accordingly.

However, it turns out that the adjust_link() callback was not
configuring the hardware in a completely correct way: while it was
setting the speed and duplex bits correctly, it wasn't telling the
hardware to actually take into account those bits rather than what the
hardware-based PHY polling mechanism has concluded. So, in fact the
adjust_link() callback was basically a no-op.

However, the network happened to be working because on the network
interfaces used by U-Boot for tftp on Armada 370 platforms because the
hardware PHY polling was enabled by the bootloader, and left enabled
by Linux. However, the second network interface not used for tftp (or
both network interfaces if the kernel is loaded from USB, NAND or SD
card) didn't had the hardware PHY polling enabled.

This patch fixes this situation by:

 (1) Making sure that the hardware PHY polling is disabled by clearing
     the MVNETA_PHY_POLLING_ENABLE bit in the MVNETA_UNIT_CONTROL
     register in the driver ->probe() function.

 (2) Making sure that the duplex and speed selections made by the
     adjust_link() callback are taken into account by clearing the
     MVNETA_GMAC_AN_SPEED_EN and MVNETA_GMAC_AN_DUPLEX_EN bits in the
     MVNETA_GMAC_AUTONEG_CONFIG register.

This patch has been tested on Armada 370 Mirabox, and now both network
interfaces are usable after boot.

copying large files to a NFS mounted host was taking absurdly large
time.

Turns out that TX BD reclaim had a sublte bug.

Loop starts off from @txbd_dirty cursor and stops when it hits a BD
still in use by controller. However when it stops it needs to keep the
cursor at that very BD to resume scanning in next iteration. However it
was erroneously incrementing the cursor, causing the next scan(s) to
fail too, unless the BD chain was completely drained out.

Since commit 82dc3c63 ("net: introduce NAPI_POLL_WEIGHT")
netif_napi_add() produces an error message if a NAPI poll weight
greater than 64 is requested.

qlcnic requests the weight as large as 256 for some of its rings, and
smaller values for other rings. For instance in qlcnic_82xx_napi_add()
I think the intention was to give the tx+rx ring a bigger weight than
to rx-only rings, but it's actually doing the opposite. So I'm assuming
the weights do not really matter much.

Just use the standard NAPI weights for all rings.

This patch adds two more ndo ops: ndo_add_rx_vxlan_port() and
ndo_del_rx_vxlan_port().

Drivers can get notifications through the above functions about changes
of the UDP listening port of VXLAN. Also, when physical ports come up,
now they can call vxlan_get_rx_port() in order to obtain the port number(s)
of the existing VXLAN interface in case they already up before them.

This information about the listening UDP port would be used for VXLAN
related offloads.
