Set rx csum default to hw checksumming again.
Remove sysfs interface for rx csum (checksumming) and TSO (large_send).
With the new hw_features it does not work to keep the old sysfs
interface in parallel. Convert options.checksum_type to new hw_features.Signed-off-by: Frank Blaschka

Driver checks if the previous dump has been cleared before taking the dump.
It doesn't take the dump if it is not cleared.Changes from v2:
Added lock to protect dump data structures from being mangled while
dumping or setting them via ethtool.Signed-off-by: Anirban Chakraborty

Added code to take FW dump.
o Driver queries FW at the init time and gets the dump template
o It takes FW dump as per the dump template
o Level of FW dump (and its size) is configured via dump flagSigned-off-by: Sritej Velaga

Sending mbox cmds require multiple steps of writing to the DB register and polling
for an ack. Gettting interrupted in the middle by a signal breaks the mbox protocol.
Use msleep() to not get interrupted.Signed-off-by: Sathya Perla

If waiting on POST returns prematurely (due to a signal), abort polling and return an error.

Added code to take FW dump via ethtool. Dump level can be controlled via setting the
dump flag. A get function is provided to query the current setting of the dump flag.
Dump data is obtained from the driver via a separate get function.Changes from v3:
Fixed buffer length issue in ethtool_get_dump_data function.
Updated kernel doc for ethtool_dump struct and get_dump_flag function.Changes from v2:
Provided separate commands for get flag and data.
Check for minimum of the two buffer length obtained via ethtool and driver and
use that for dump buffer
Pass up the driver return error codes up to the caller.
Added kernel doc comments.Signed-off-by: Anirban Chakraborty

No matter what kind of header mangling occurs due to IP options
processing, rt->rt_dst will always equal iph->daddr in the packet.So we can safely use iph->daddr instead of rt->rt_dst here.

We already copy the 4-byte nexthop from the options block into

This should also fix updating of vlan_features and propagating changes to
VLAN devices on the bond.Side effect: it allows user to force-disable some offloads on the bond
interface.Note: NETIF_F_VLAN_CHALLENGED is managed by bond_fix_features() now.

Remove all remaining references to rt->rt_{src,dst}
by using dest->dst_saddr to cache saddr (used for TUN mode).
For ICMP in FORWARD hook just restrict the rt_mode for NAT
to disable LOCALNODE. All other modes do not allow
IP_VS_RT_MODE_RDR, so we should be safe with the ICMP
forwarding. Using cp->daddr as replacement for rt_dst
is safe for all modes except BYPASS, even when cp->dest is
NULL because it is cp->daddr that is used to assign cp->dest
for sync-ed connections.Signed-off-by: Julian Anastasov

Michał Mirosław's patch (http://patchwork.ozlabs.org/patch/94421/) fixes the
issue (http://patchwork.ozlabs.org/patch/94188/) about not populating FCoE related
flags correctly on vlan devices. However, only NETIF_F_FCOE_CRC is part of the
NETIF_F_ALL_TX_OFFLOADS right now, where weed NETIF_F_FCOE_MTU and NETIF_F_FSO
as well.Therefore, add NETIF_F_ALL_FCOE to indicate feature flags used by FCoE TX offloads.
These include NETIF_F_FCOE_CRC, NETIF_F_FCOE_MTU, and NETIF_F_FSO and add them to
be part of NETIF_F_ALL_TX_OFFLOADS. This would eventually make sure all FCoE needed
flags are populated properly to vlan devices.Signed-off-by: Yi Zou

Fix VLAN features propagation for devices which change vlan_features.
For this to work, driver needs to make sure netdev_features_changed()
gets called after the change (it is e.g. after ndo_set_features()).Side effect is that a user might request features that will never
be enabled on a VLAN device.Signed-off-by: Michał Mirosław

When removing last vlan from a device, garp_uninit_applicant() calls
synchronize_rcu() to make sure no user can still manipulate struct
garp_applicant before we free it.Use call_rcu() instead, as a step to further net_device dismantle
optimizations.Add the temporary garp_cleanup_module() function to make sure no pending
call_rcu() are left at module unload time [ this will be removed when
kfree_rcu() is available ]Signed-off-by: Eric Dumazet

Resending this patch with few changes.
Avoid multiple queues when MSI or MSI-X not available
Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in
the kernel. This will make number of tx and rx queues equal when MSI/X
is not configured thus providing better performance.Signed-off-by: Bhavesh Davda

While trying to remove useless synchronize_rcu() calls, I found l2tp is
indeed incorrectly using two of such calls, but also bumps tunnel
refcount after list insertion.tunnel refcount must be incremented before being made publically visible
by rcu readers.This fix can be applied to 2.6.35+ and might need a backport for older
kernels, since things were shuffled in commit fd558d186df2c

Start/stop TX queue is controlled by TX queue "used" counter.
It is incremented while WRBs are posted to TX queue and
decremented when TX completions are received. This counter was
getting decremented before HW is informed about processing of TX
completions. As used counter is decremented, transmit function
posts new WRBs and creates completion queue full scenario in HW.Signed-off-by: Padmanabh Ratnakar
