6c53b1b15e smsc9420: prevent BUG() if ethtool is called with interface down
This patch fixes a null pointer dereference BUG() if ethtool is used on
an smsc9420 interface while it is down, because the phy_dev is only
allocated while the interface is up.

The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the

cd7a3b75ba smsc9420: fix big endian rx checksum offload
The cpu_to_le16 here looks suspicious to me, I don't think we need it
because put_unaligned_le16 also does this.

I don't currently have any big endian hardware with a PCI bus available
to test on, so I haven't been able to verify this.

196b7e1b9c smsc9420: handle magic field of ethtool_eeprom
ethtool.h says the driver should set the magic field in get_eeprom and
verify it in set_eeprom.  This patch adds this functionality using an
arbitary driver-specific magic value constant (0x9420).

but 0 is tested afterwards.  This patch fixes another, so the timeout

1609559547 smsc9420: fix interrupt signalling test failures
smsc9420 performs an interrupt signalling test when the interface is
brought up.  The current code mistakenly sets its test flag to false
AFTER enabling the software interrupt source, making failure quite
likely.

This patch changes the code to set the test flag BEFORE enabling
interrupts. I've also removed an smp_wmb because the following spinlock
provides an implicit memory barrier.

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.

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..

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.
