net: fix 64 bit counters on 32 bit arches

2010-07-07T21:58:56Z

There is a small possibility that a reader gets incorrect values on 32 bit arches. SNMP applications could catch incorrect counters when a 32bit high part is changed by another stats consumer/provider. One way to solve this is to add a rtnl_link_stats64 param to all ndo_get_stats64() methods, and also add such a parameter to dev_get_stats(). Rule is that we are not allowed to use dev->stats64 as a temporary storage for 64bit stats, but a caller provided area (usually on stack) Old drivers (only providing get_stats() method) need no changes.

sfc: Add support for RX flow hash control

2010-06-30T21:10:04Z

Allow ethtool to query the number of RX rings, the fields used in RX flow hashing and the hash indirection table. Allow ethtool to update the RX flow hash indirection table. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

ethtool: Change ethtool_op_set_flags to validate flags

2010-06-30T21:09:35Z

ethtool_op_set_flags() does not check for unsupported flags, and has no way of doing so. This means it is not suitable for use as a default implementation of ethtool_ops::set_flags. Add a 'supported' parameter specifying the flags that the driver and hardware support, validate the requested flags against this, and change all current callers to pass this parameter. Change some other trivial implementations of ethtool_ops::set_flags to call ethtool_op_set_flags().

sfc: Implement message level control

2010-06-25T05:13:22Z

Replace EFX_ERR() with netif_err(), EFX_INFO() with netif_info(), EFX_LOG() with netif_dbg() and EFX_TRACE() and EFX_REGDUMP() with netif_vdbg(). Replace EFX_ERR_RL(), EFX_INFO_RL() and EFX_LOG_RL() using explicit calls to net_ratelimit(). Implement the ethtool operations to get and set message level flags, and add a 'debug' module parameter for the initial value. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

sfc: Create multiple TX queues

2010-04-28T19:44:44Z

Create a core TX queue and 2 hardware TX queues for each channel. If separate_tx_channels is set, create equal numbers of RX and TX channels instead. Rewrite the channel and queue iteration macros accordingly. Eliminate efx_channel::used_flags as redundant. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

sfc: Test only the first pair of TX queues

2010-04-28T19:44:43Z

This makes no immediate difference, but we definitely do not want to test all TX queues once we allocate a pair of TX queues to each channel. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller
