ethtool: Support for configurable RSS hash function

2014-12-09T02:07:10Z

This patch extends the set/get_rxfh ethtool-options for getting or setting the RSS hash function. It modifies drivers implementation of set/get_rxfh accordingly. This change also delegates the responsibility of checking whether a modification to a certain RX flow hash parameter is supported to the driver implementation of set_rxfh. User-kernel API is done through the new hfunc bitmask field in the ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an index in the new string-set ETH_SS_RSS_HASH_FUNCS. Got approval from most of the relevant driver maintainers that their driver is using Toeplitz, and for the few that didn't answered, also assumed it is Toeplitz.

ethtool: Add generic options for tunables

2014-09-05T19:12:20Z

This patch adds new ethtool cmd, ETHTOOL_GTUNABLE & ETHTOOL_STUNABLE for getting tunable values from driver. Add get_tunable and set_tunable to ethtool_ops. Driver implements these functions for getting/setting tunable value. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller

ethtool: Replace ethtool_ops::{get,set}_rxfh_indir() with {get,set}_rxfh()

2014-06-03T01:42:44Z

ETHTOOL_{G,S}RXFHINDIR and ETHTOOL_{G,S}RSSH should work for drivers regardless of whether they expose the hash key, unless you try to set a hash key for a driver that doesn't expose it. Signed-off-by: Ben Hutchings Acked-by: Jeff Kirsher

ethtool: Disallow ETHTOOL_SRSSH with both indir table and hash key unchanged

2014-05-19T00:29:42Z

This would be a no-op, so there is no reason to request it. This also allows conversion of the current implementations of ethtool_ops::{get,set}_rxfh_indir to ethtool_ops::{get,set}_rxfh with no change other than their parameters. Signed-off-by: Ben Hutchings

ethtool: Support for configurable RSS hash key

This ethtool patch primarily copies the ioctl command data structures from/to the User space and invokes the driver hook. Signed-off-by: Venkat Duvvuru Signed-off-by: David S. Miller

ethtool: Document the general convention for VLAs in kernel space

2014-02-12T22:33:03Z

Various ethtool command structures are declared with zero-length array at the end which are intended to be variable-length in userland (relying on lack of compiler bounds checking). However, in the kernel the structure and array are always allocated and passed to driver operations separately. Make that explicit. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

ethtool.h: MDI setting support

2012-08-21T08:19:54Z

This change modifies the core ethtool struct to allow a driver to support setting of MDI/MDI-X state for twisted pair wiring. This change uses a previously reserved u8 and should not change any binary compatibility of ethtool. Also as per Ben Hutchings' suggestion, the capabilities are stored in a separate byte so the driver can report if it supports changing settings. see thread: http://kerneltrap.org/mailarchive/linux-netdev/2010/11/17/6289820/thread see ethtool patches titled: ethtool: allow setting MDI-X state Signed-off-by: Jesse Brandeburg CC: Ben Hutchings Tested-by: Aaron Brown aaron.f.brown@intel.com Signed-off-by: Jeff Kirsher
