SMSC LAN9500 has dual purpose GPIO/LED pins, and by default at power-on
these are configured as GPIOs.  This means that if LEDs are fitted they
won't ever light.

This patch sets them to be LED outputs for speed, duplex and
link/activity.

Work-around for Tegra USB EHCI host controller limitation. Outgoing USB
network packets must be 32 byte alligned.

Bug 631234, 634022, 638227

Change-Id: Iba7be8305037e93df4d47d9b1f63a0907fafded1

fixes a few bugs with skid buffer usage, adds device ID for SMSC 9514

some hardware requires transmitting zero-length packets and not the one-byte
packet that is currently being transmitted

On SMP systems, the SMSC911x registers may be accessed by multiple CPUs
and this seems to put the chip in an inconsistent state. The patch adds
spinlocks to the smsc911x_reg_read, smsc911x_reg_write,
smsc911x_rx_readfifo and smsc911x_tx_writefifo functions.

It is common to manipulate the routing table after configuring PPP device.
Since both PPPoLAC and PPPoPNS run over IP, care must be taken to make sure
that there is no loop in the routing table.
Although this can be done by adding a host route, it might still cause
problems when the interface is down for some reason.

To solve this, this patch forces both drivers to bind an interface before
creating PPP channel, so the system will not re-route the tunneling sockets
to another interface when the original one is down. Another benefit is that
now the host route is no longer required, so there is no need to remove it
when PPP channel is closed.

PPP driver guarantees that no thread will be executing start_xmit() after
returning from ppp_unregister_channel(). To achieve this, a spinlock (downl)
is used. In pppolac_release(), ppp_unregister_channel() is called after sk_udp
is locked. At the same time, another thread might be running in pppolac_xmit()
with downl. Thus a deadlock will occur if the thread tries to lock sk_udp.
The same situation might happen on sk_raw in pppopns_release().
