10 years agonet: dont update dev->trans_start in 10GB drivers

net: dont update dev->trans_start in 10GB drivers

Followup of commits 9d21493b4beb8f918ba248032fefa393074a5e2b
and 08baf561083bc27a953aa087dd8a664bb2b88e8e
(net: tx scalability works : trans_start)
(net: txq_trans_update() helper)

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Multi queue drivers can
avoid one cache miss (on dev->trans_start) in their start_xmit()
handler.

Exceptions are NETIF_F_LLTX drivers (vxge & tehuti)

wimax/i2400m: usb: fix device reset on autosuspend while not yet idle

When the i2400m is connected to a network, the host interface (USB)
cannot be suspended. For that to happen, the device has to have
negotiated with the basestation to put the link on IDLE state.

If the host tries to put the device in standby while it is connected
but not idle, the device resets, as the driver should not do that.

To avoid triggering that, when the USB susbsytem requires the driver
to autosuspend the device, the driver checks if the device is not yet
idle. If it is not, the request is requested (will be retried again
later on after the autosuspend timeout). At some point the device will
enter idle and the request will succeed (unless of course, there is
network traffic, but at that point, there is no idle neither in the
link or the host interface).

wimax/i2400m: allow kernel commands to device to be logged too

By running 'echo 1 > /sys/kernel/debug/wimax:wmxX/i2400m/trace_msg_from_user',
the driver will echo to user space all the commands being sent to the

However, this only helps with the commands being sent from user space;
with this patch, the trace hook is moved to i2400m_msg_to_dev(), which
is the single access point for running commands to the device (both by
user space and the kernel driver). This allows better debugging by
having a complete stream of commands/acks and reports.

Don Skidmore [Wed, 27 May 2009 03:40:47 +0000]
ixgbe: fix 82598 SFP initialization after driver load.

If we loaded the driver with out a SFP module plugged in it would
leave it in a state that make it later unable to link when a module
was plugged in.  This patch corrects that by:

ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from
after get_invariants() to after reset_hw() as now reset_hw() is
where this condition will be indentified.

ixgbe_reset_hw_82598() - Enable this function to now return
IXGBE_ERR_SFP_NOT_PRESENT.

ixgbe_identify_sfp_module_generic() - This where the lack of SFP
module is detected.  Modifications are added to allow a different
return value for modules that just haven't been plugged in yet.

Other functions were updated to allow correct logging.

Jesper Dangaard Brouer [Tue, 26 May 2009 13:50:48 +0000]
igb: Record host memory receive overflow in net_stats

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".

RQDPC (Receive Queue Drop Packet Count).  It counts the number of

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.

Some devices, (particularly loopback) dont need trans_start update, because
they dont have transmit watchdog. We could add a new device flag, or rely
on fact that txq->tran_start can be updated is txq->xmit_lock_owner is

10 years agomISDN: Fix TEI and SAPI handling

mISDN: Fix TEI and SAPI handling

Added SAPI value to use SAPIs different than 0.

Now fixed TEIs work in NT mode. This allows PTP endpoint to be connected
to PTMP ports together with other PTMP endpoints.

New enhanced version, thanks to Sam Ravnborg <sam@ravnborg.org> for the
hints.

10 years agogianfar: fix BUG under load after introduction of skb recycling
Lennert Buytenhek [Mon, 25 May 2009 07:42:34 +0000]
gianfar: fix BUG under load after introduction of skb recycling

Since commit 0fd56bb5be6455d0d42241e65aed057244665e5e ("gianfar:
Add support for skb recycling"), gianfar puts skbuffs that are in
the rx ring back onto the recycle list as-is in case there was a
receive error, but this breaks the following invariant: that all
skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD.

The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done
twice on skbuffs recycled in this way, causing there not to be enough
room in the skb anymore to receive a full packet, eventually leading
to an skb_over_panic from gfar_clean_rx_ring() -> skb_put().

Resetting the skb->data pointer to skb->head + NET_SKB_PAD before
putting the skb back onto the recycle list restores the mentioned
invariant, and should fix this issue.

10 years agoskbuff: Move new code into __copy_skb_header

skbuff: Move new code into __copy_skb_header

Hi:

skbuff: Move new __skb_clone code into __copy_skb_header

It seems that people just keep on adding stuff to __skb_clone
instead __copy_skb_header.  This is wrong as it means your brand-new
attributes won't always get copied as you intended.

This patch moves them to the right place, and adds a comment to
prevent this from happening again.
