Steve Glendinning 1373c0fdbc smsc911x: leave RX_STOP interrupt permanently enabled
smsc911x_set_multicast_list currently performs the only non-atomic
read-modify-write of INT_EN.  This patch permanently enables the
RXSTOP_INT interrupt, and changes the ISR to only conditionally run the
multicast filter workaround code.

Ben Hutchings 288379f050 net: Remove redundant NAPI functions
Following the removal of the unused struct net_device * parameter from
the NAPI functions named *netif_rx_* in commit 908a7a1, they are
exactly equivalent to the corresponding *napi_* functions and are
therefore redundant.

Steve Glendinning 08168f7164 smsc911x: register irq with device name, not driver name
This change lets "cat /proc/interrupts" show the name of the ethernet
device (e.g. eth0) rather than the driver name (smsc911x).

Steve Glendinning 702403af28 smsc911x: fix smsc911x_reg_read compiler warning
if this code path is ever hit, the platform_data struct isn't properly
configured with a bus width flag so the device won't work (hence the
BUG()).

This patch adds a dummy return statement to eliminate this compiler
warning:

drivers/net/smsc911x.c: In function 'smsc911x_reg_read':
drivers/net/smsc911x.c:148: warning: control reaches end of non-void function

Steve Glendinning d45227391c smsc911x: fix platform resource call during module unload
This patch fixes a typo, the platform_get_resource calls in
smsc911x_drv_remove are supposed to look the same as those in
smsc911x_drv_probe.

Steve Glendinning dd04519388 smsc911x: fix BUG if module is removed while interface is up
If the module is removed while its interface is up, smsc911x_stop is not
called until after smsc911x_drv_remove has disposed of phy_dev.  This
patch changes the stop method to handle this situation.

This is a different problem to the one reported by dfoley@telus.net.

Neil Horman 908a7a16b8 net: Remove unused netdev arg from some NAPI interfaces.
When the napi api was changed to separate its 1:1 binding to the net_device
struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
vestigual net_device structure parameter.  This patch cleans up that api by
properly removing it..

Steve Glendinning bc02ff95fe net: Refactor full duplex flow control resolution
These 4 drivers have identical full duplex flow control resolution
functions.  This patch changes them all to use one common function.

The function in question decides whether a device should enable TX and
RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this
should also be useful for other drivers.

Steve Glendinning fd9abb3d97 SMSC LAN911x and LAN921x vendor driver
Attached is a driver for SMSC's LAN911x and LAN921x families of embedded
ethernet controllers.

There is an existing smc911x driver in the tree; this is intended to
replace it.  Dustin McIntire (the author of the smc911x driver) has
expressed his support for switching to this driver.

This driver contains workarounds for all known hardware issues, and has
been tested on all flavours of the chip on multiple architectures.

This driver now uses phylib, so this patch also adds support for the
device's internal phy
