net: fix ETHTOOL_SFEATURES compatibility with old ethtool_ops.set_flags

2011-05-26T18:13:59Z

Current code squashes flags to bool - this makes set_flags fail whenever some ETH_FLAG_* equivalent features are set. Fix this. Signed-off-by: Michał Mirosław Signed-off-by: David S. Miller

ethtool: Added support for FW dump

2011-05-13T18:37:28Z

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.

net: Allow ethtool to set interface in loopback mode.

2011-05-08T22:59:12Z

This patch enables ethtool to set the loopback mode on a given interface. By configuring the interface in loopback mode in conjunction with a policy route / rule, a userland application can stress the egress / ingress path exposing the flows of the change in progress and potentially help developer(s) understand the impact of those changes without even sending a packet out on the network. Following set of commands illustrates one such example - a) ip -4 addr add 192.168.1.1/24 dev eth1 b) ip -4 rule add from all iif eth1 lookup 250 c) ip -4 route add local 0/0 dev lo proto kernel scope host table 250 d) arp -Ds 192.168.1.100 eth1 e) arp -Ds 192.168.1.200 eth1 f) sysctl -w net.ipv4.ip_nonlocal_bind=1 g) sysctl -w net.ipv4.conf.all.accept_local=1 # Assuming that the machine has 8 cores h) taskset 000f netserver -L 192.168.1.200 i) taskset 00f0 netperf -t TCP_CRR -L 192.168.1.100 -H 192.168.1.200 -l 30 Signed-off-by: Mahesh Bandewar Acked-by: Ben Hutchings Signed-off-by: David S.

ethtool: remove phys_id from ethtool_ops

2011-05-08T19:49:33Z

After that all the upstream kernel drivers now use phys_id, and the old ethtool_ops interface (phys_id) can be removed. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

net: fix hw_features ethtool_ops->set_flags compatibility

2011-04-22T00:21:43Z

__ethtool_set_flags() was not taking into account features set but not user-toggleable. Since GFLAGS returns masked dev->features, EINVAL is returned when passed flags differ to it, and not to wanted_features. Signed-off-by: Michał Mirosław Signed-off-by: David S. Miller

ethtool: allow custom interval for physical identification

2011-04-15T04:15:49Z

When physical identification of an adapter is done by toggling the mechanism on and off through software utilizing the set_phys_id operation, it is done with a fixed duration for both on and off states. Some drivers may want to set a custom duration for the on/off intervals. This patch changes the API so the return code from the driver's entry point when it is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to cycle the on/off states, and updates the drivers that have already been converted to use the new set_phys_id and use the synchronous method for identifying an adapter. The physical identification frequency set in the updated drivers is based on how it was done prior to the introduction of set_phys_id. Compile tested only. Also fixes a compiler warning in sfc. v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE v3: fold patchset into single patch and cleanup per Ben's feedback Signed-off-by: Bruce Allan Cc: Ben Hutchings Cc: Sathya Perla Cc: Subbu Seetharaman Cc: Ajit Khaparde Cc: Michael Chan Cc: Eilon Greenstein Cc: Divy Le Ray Cc: Don Fry Cc: Jon Mason Cc: Solarflare linux maintainers Cc: Steve Hodgson Cc: Stephen Hemminger Cc: Matt Carlson Acked-by: Jon Mason Acked-by: Ben Hutchings Signed-off-by: David S.

net: ethtool support to configure number of channels

2011-04-13T18:31:04Z

Ethtool support to configure RX, TX and other channels. combined field in struct ethtool_channels to reflect set of channel (RX, TX or other). Other channel can be link interrupts, SR-IOV coordination etc. ETHTOOL_GCHANNELS will report max and current number of RX channels, max and current number of TX channels, max and current number of other channel or max and current number of combined channel. Number of channel can be modify upto max number of channel through ETHTOOL_SCHANNELS command. Ben Hutchings: o define 'combined' and 'other' types. Most multiqueue drivers pair up RX and TX queues so that most channels combine RX and TX work. o Please could you use a kernel-doc comment to describe the structure.
