netdev: drivers should make ethtool_ops const

2009-09-02T08:03:33+00:00

No need to put ethtool_ops in data, they should be const.

igb: cleanup flow control configuration to make requested/current more clear

2009-07-26T16:47:02+00:00

This patch cleans up the flow control configuration for igb to make it a
bit more readable in regards to what the requested and current modes are.
This should help with the maintainability of the current igb driver in
regards to flow control.

igb: remove unused switch statement from igb_set_wol

2009-07-26T16:46:56+00:00

There is a switch statement in igb_set_wol that defaults to break and
doesn't actually do anything.  As such it should be removed.

igb: remove media type fiber as it is misleading

2009-07-26T16:46:41+00:00

The current igb driver only supports copper and serdes.  The fiber media
type is a holdover from earlier NICs as the current nics supported by igb
all use serdes when communicating over a fiber connection.  As a result we
can remove media type fiber without losing any functionality.

igb: Record host memory receive overflow in net_stats

2009-05-27T03:35:06+00:00

Based on previous patch from Jesper Dangaard Brouer.

The RNBC (Receive No Buffers Count) register for the 82576, indicate
that frames were received when there were no available buffers in host
memory to store those frames (receive descriptor head and tail
pointers were equal).  The packet is still received by the NIC if
there is space in the FIFO on the NIC.

As the RNBC value is not a packet drop, the driver stores this value
in net_stats.rx_fifo_errors to indicate that there were no system
buffers available for the incoming packet.  Actual dropped packets
are counted in the MPC value.

Saving the stats in dev->net_stats makes it visible via
/proc/net/dev as "fifo", and thus viewable to ifconfig
as "overruns" and 'netstat -i' as "RX-OVR".

The Receive No Buffers Count (RNBC) can already be queried by
ethtool -S as "rx_no_buffer_count".

igb: Implement reading of reg RQDPC (Receive Queue Drop Packet Count)

2009-05-27T03:35:05+00:00

Based on the previous patches from Jesper Dangaard Brouer 

Implement reading the per queue drop stats register
RQDPC (Receive Queue Drop Packet Count).  It counts the number of
packets dropped by a queue due to lack of descriptors available.

Notice RQDPC (Receive Queue Drop Packet Count) stats only gets
incremented, if the DROP_EN bit it set (in the SRRCTL register
for that queue).  If DROP_EN bit is NOT set, then the some what
equivalent count is stored in RNBC (not per queue basis).

The RQDPC register is only 12 bit, thus the precision might
suffer due to overrun in-netween the watchdog polling interval.

igb/igbvf: set rx csum always enabled in hw, disable via sw

2009-05-06T22:33:41+00:00

An issue was found in which rx checksum could not be enabled without
resetting the interface.  The issue was the hardware enable was not being
done via ethtool.  To resolve this issue and prevent conflicts with VF
configuration we will leave the feature always enabled in hardware, and
then in software we will choose to ignore the results via a sw flag.

igb: Enable SCTP checksum offloading

2009-04-28T08:53:14+00:00

Originally from: Vlad Yasevich 

This patch, both the driver portion and the sctp code was
modified by Jesse Brandeburg and is

Copyright(c) 2009 Intel Corporation.

Thanks go to Vlad for starting this work.

Intel 82576 chipset supports SCTP checksum offloading.  This
patch enables this functionality in the driver.  A new NETIF
feature is introduced for SCTP checksum offload.  If the driver
supports CRC32c checksum, it can set this feature flag.  The
hardware can offload both transmit and receive.

igb: cleanup igb loopback path

2009-04-02T07:59:08+00:00

The code path for setting up phy loopback testing was out of date and was
setting bits it didn't need to.  This change cleans up the code path and
removes some code that has no effect on teh driver.
