Existing code assumes that del_timer returns true for alive conntrack
entries. However, this is not true if reliable events are enabled.
In that case, del_timer may return true for entries that were
just inserted in the dying list. Note that packets / ctnetlink may
hold references to conntrack entries that were just inserted to such
list.
This patch fixes the issue by adding an independent timer for
event delivery. This increases the size of the ecache extension.
Still we can revisit this later and use variable size extensions
to allocate this area on demand.

Make the device tree probe function more data-driven, so that it no longer
searches the 'compatible' property more than once. The of_device_id[] array
allows for per-entry private data, so we use that to store details about each
type of node that the driver supports. This removes the need to check the
'compatible' property inside the probe function.
The driver supports four types on MDIO devices:
1) Gianfar MDIO nodes that only map the MII registers
2) Gianfar MDIO nodes that map the full MDIO register set
3) eTSEC2 MDIO nodes (which map the full MDIO register set)
4) QE MDIO nodes (which map only the MII registers)
Gianfar, eTSEC2, and QE have different mappings for the TBIPA register, which
is needed to initialize the TBI PHY. In addition, the QE needs a special
hack because of the way the device tree is ordered.
All of this information is encapsulated in the fsl_pq_mdio_data structure,
so when an MDIO node is probed, per-device data and functions are used
to determine how to initialize the device.

Currently RSS rings are not created in a multi-channel config.
RSS rings can be created on one (out of four) interfaces per port in a
multi-channel config. Doing this insulates the driver from a FW bug wherin
multi-channel config is wrongly reported even when not enabled. This also
helps performance in a multi-channel config, as one interface per port gets

This complements patch "net-forcedeth: fix TX timeout caused by TX
pause on down link" which ensures that a lock-up sequence is not sent
to the NIC. Present patch ensures that if a NIC is already locked-up,
the driver will recover from it when initializing the device.
It does the equivalent of the following recovery sequence:
- write NVREG_TX_PAUSEFRAME_ENABLE_V1 to eth1's register
NvRegTxPauseFrame
- write NVREG_XMITCTL_START to eth1's register
NvRegTransmitterControl
- write 0 to eth1's register NvRegTransmitterControl
(this is at the heart of the "unbricking" sequence mentioned in patch
"net-forcedeth: fix TX timeout caused by TX pause on down link")
Tested:
- hardware is MCP55 device id 10de:0373 (rev a3), dual-port
- reboot a kernel without any of patches mentioned
- freeze the NIC (details on description for commit "net-forcedeth:
fix TX timeout caused by TX pause on down link")
- wait 5mn until ping hangs & TX timeout in dmesg
- reboot on kernel with present patch
- host is immediatly operational, no TX timeout

On some dual-port forcedeth devices such as MCP55 10de:0373 (rev a3),
when autoneg & TX pause are enabled while port is connected but
interface is down, the NIC will eventually freeze (TX timeouts,
network unreachable).
This patch ensures that TX pause is not configured in hardware when
interface is down. The TX pause request will be honored when interface
is later configured.
Tested:
- hardware is MCP55 device id 10de:0373 (rev a3), dual-port
- eth0 connected and UP, eth1 connected but DOWN
- without this patch, following sequence would brick NIC:
ifconfig eth0 down
ifconfig eth1 up
ifconfig eth1 down
ethtool -A eth1 autoneg off rx on tx off
ifconfig eth1 up
ifconfig eth1 down
ethtool -A eth1 autoneg on rx on tx on
ifconfig eth1 up
ifconfig eth1 down
ifup eth0
sleep 120 # or longer
ethtool eth1
Just in case, sequence to un-brick:
ifconfig eth0 down
ethtool -A eth1 autoneg off rx on tx off
ifconfig eth1 up
ifconfig eth1 down
ifup eth0
- with this patch: no TX timeout after "bricking" sequence above
Details:
- The following register accesses have been identified as the ones
causing the NIC to freeze in "bricking" sequence above:
- write NVREG_TX_PAUSEFRAME_ENABLE_V1 to eth1's register NvRegTxPauseFrame
- write NVREG_MISC1_PAUSE_TX | NVREG_MISC1_FORCE to eth1's register NvRegMisc1
- write 0 to eth1's register NvRegTransmitterControl

When tearing down a net namespace, ipv4 mr_table structures are freed
without first deactivating their timers. This can result in a crash in
run_timer_softirq.
This patch mimics the corresponding behaviour in ipv6.
Locking and synchronization seem to be adequate.
We are about to kfree mrt, so existing code should already make sure that
no other references to mrt are pending or can be created by incoming traffic.
The functions invoked here do not cause new references to mrt or other
race conditions to be created.
Invoking del_timer_sync guarantees that ipmr_expire_timer is inactive.
Both ipmr_expire_process (whose completion we may have to wait in
del_timer_sync) and mroute_clean_tables internally use mfc_unres_lock
or other synchronizations when needed, and they both only modify mrt.

With a low enough MSS on the link partner and TSO enabled locally, the
networking stack can periodically send a very large (e.g. 64KB) TCP
message for which the driver will attempt to use more Tx descriptors than
are available by default in the Tx ring. This is due to a workaround in
the code that imposes a limit of only 4 MSS-sized segments per descriptor
which appears to be a carry-over from the older e1000 driver and may be
applicable only to some older PCI or PCIx parts which are not supported in
e1000e. When the driver gets a message that is too large to fit across the
configured number of Tx descriptors, it stops the upper stack from queueing
any more and gets stuck in this state. After a timeout, the upper stack
assumes the adapter is hung and calls the driver to reset it.
Remove the unnecessary limitation of using up to only 4 MSS-sized segments
per Tx descriptor, and put in a hard failure test to catch when attempting
to check for message sizes larger than would fit in the whole Tx ring.
Refactor the remaining logic that limits the size of data per Tx descriptor
from a seemingly arbitrary 8KB to a limit based on the dynamic size of the
Tx packet buffer as described in the hardware specification.
Also, fix the logic in the check for space in the Tx ring for the next
largest possible packet after the current one has been successfully queued
for transmit, and use the appropriate defines for default ring sizes in
e1000_probe instead of magic values.
This issue goes back to the introduction of e1000e in 2.6.24 when it was
split off from e1000.

When moving a net device from one net namespace to another
net namespace,dev_change_net_namespace calls NETDEV_DOWN
event,so the original net namespace's dst entries which
beloned to this net device will be put into dst_garbage
list.
then dev_change_net_namespace will set this net device's
net to the new net namespace.
If we unregister this net device's driver, this will trigger
the NETDEV_UNREGISTER_FINAL event, dst_ifdown will be called,
and get this net device's dst entries from dst_garbage list,
put these entries' dev to the new net namespace's lo device.
It's not what we want,actually we need these dst entries hold
the original net namespace's lo device,this incorrect device
holding will trigger emg message like below.
unregister_netdevice: waiting for lo to become free. Usage count = 1
so we should call NETDEV_UNREGISTER_FINAL event in
dev_change_net_namespace too,in order to make sure dst entries
already in the dst_garbage list, we need rcu_barrier before we
call NETDEV_UNREGISTER_FINAL event.
