Up until now the tg3 driver would call netif_napi_add() for the maximum
number of NAPI instances the driver could use. The problem is that
netpoll could call tg3_poll() on instances that are not active. The net
effect is that the driver will crash attempting to dereference
uninitialized pointers.
The fix is to only allocate as many NAPI instances as the driver would
use in tg3_open() and deleted them in tg3_close().

Most e1000e parts support batching writebacks. The problem with this is
that when some of the TADV or TIDV timers are not set, Tx can sit forever.

This improves bus utilization and removes partial writes on e1000e,

This patch contains the following DCA improvements to myri10ge:
1) Finally move myri10ge to use dca3 API
2) Disable PCIe relaxed ordering when enabling DCA on
myri10ge. This provides a performance boost on Nehalem
based Xeons
3) Make sure to properly initialize NIC's DCA state when it is enabled,
rather than giving the NIC a bogus tag (0) and waiting for
the first received packet to trigger an update. Not using a
real tag can cause hardware exceptions on some motherboards
when a CPU socket is empty.
3) Always update the cached CPU when our interrupt affinity changes
so as to avoid excessive calls to dca3_get_tag()

Compex FreedomLine 32 PnP-PCI2 cards have only TP and BNC connectors but the
SROM contains AUI port too. When TP loses link, the driver switches to
non-existing AUI port (which reports that carrier is always present).
Connecting TP back generates LinkPass interrupt but de_media_interrupt() is
broken - it only updates the link state of currently connected media, ignoring
the fact that LinkPass and LinkFail bits of MacStatus register belong to the
TP port only (the chip documentation says that).
This patch changes de_media_interrupt() to switch media to TP when link goes
up (and media type is not locked) and also to update the link state only when
the TP port is used.
Also the NonselPortActive (and also SelPortActive) bits of SIAStatus register
need to be cleared (by writing 1) after reading or they're useless.

system, reducing the performance hit that is caused by __skb_linearize(),
particularly for large send. This is fixed in this patch for all Intel e1000,
e1000e, igb, ixgbe, and ixgbe drivers since this should be beneficial
to all devices supported by these drivers.

This patch adds support for the Intel(r) DH89xxCC series. The new
device will be using Intel(r) i347-AT4 and Marvell(r) M88E1322 and
M88E1112 PHYs. Support for these devices has also been added here.

This change corrects an issue in which we were setting all flag bits except
for promisc instead of clearing the promisc bits due to the incorrect use
of an |= instead of an &=.

For non-managed versions of 82579, set the bit that prevents the hardware
from automatically configuring the PHY after resets only when the driver
performs a reset, clear the bit after resets. This is so the hardware can
configure the PHY automatically when the part is reset in a manner that is
not controlled by the driver (e.g. in a virtual environment via PCI FLR)
otherwise the PHY will be mis-configured causing issues such as failing to
link at 1000Mbps.
For managed versions of 82579, keep the previous behavior since the
manageability firmware will handle the PHY configuration.

The subject workaround was causing CRC errors due to writing the wrong
register with updates of the RCTL register. It was also found that the
workaround function which modifies the RCTL register was being called in
the middle of a read-modify-write operation of the RCTL register, so the
function call has been moved appropriately. Lastly, jumbo frames must not
be allowed when CRC stripping is disabled by a module parameter because the
workaround requires the CRC be stripped.

On 82579, there is a hardware bug that can cause received packets to not
get transferred from the PHY to the MAC due to K1 (a power saving feature
of the PHY-MAC interconnect similar to ASPM L1). Since the MAC controls
the accounting of missed packets, these will go unnoticed. Workaround the
issue by setting the K1 beacon duration according to the link speed.

Two recent patches to cleanup the reset[1] and initial PHY configuration[2]
code paths for ICH/PCH devices inadvertently left out a 10msec delay and
device ID check respectively which are necessary for the 82566DC (device id
0x104b) to be configured properly, otherwise it will not get link.

Since the hardware is prevented from performing automatic PHY configuration
(the driver does it instead), the OEM_WRITE_ENABLE bit in the EXTCNF_CTRL
register will not get cleared preventing the SMBus address and the LED
configuration to be written to the PHY registers. On 82579, do not check
the OEM_WRITE_ENABLE bit.

When going to Sx, disable gigabit in PHY (e1000_oem_bits_config_ich8lan)
in addition to the MAC before configuring PHY wakeup otherwise the PHY
configuration writes might be missed. Also write the LED configuration
and SMBus address to the PHY registers (e1000_oem_bits_config_ich8lan and
e1000_write_smbus_addr, respectively). The reset is no longer needed
since re-auto-negotiation is forced in e1000_oem_bits_config_ich8lan and
leaving it in causes issues with auto-negotiating the link.

adapter->cmb.cmb is initialized when the device is opened and freed when
it's closed. Accessing it unconditionally during resume results either
in a crash (NULL pointer dereference, when the interface has not been
opened yet) or data corruption (when the interface has been used and
brought down adapter->cmb.cmb points to a deallocated memory area).
