2012-10-10Gracefully handle failure of register dump pretty-printerBen Hutchings1-3/+10
If we have a pretty-printer matching the driver name for a register dump, but it doesn't handle the reported dump version, then we currently fail and print: Cannot dump registers: Success Instead, fall back to hex dump. Also, don't use perror() to explain a failure of dump_regs(). errno is not meaningful in either failure case. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-10-05ethtool: --set-eee sends ETHTOOL_SEEE ioctl even if nothing changedBruce Allan1-1/+1
When setting EEE parameters with the --set-eee command line option, ethtool will send the ETHTOOL_SEEE ioctl down to the driver even if none of the provided parameters are a change from current settings. Simply ignore it when that happens as done with other ethtool commands.

2012-09-06ethtool: don't overwrite useful bits in advertising bitfieldJohan Gunnarsson1-14/+77
There are bits in this bitfield that we want to leave untouched (PAUSE and ASYM_PAUSE bits) when changing other bits (speed and duplex bits.) Previously, these were always overwritten to zero when running commands like "ethtool -s eth0 speed 10 duplex full autoneg off".

2012-09-06ethtool: allow setting MDI-X stateJesse Brandeburg1-10/+45
A bit ago ethtool added support for reading MDI-X state, this patch finishes the implementation, adding the complementary write command. Add support to ethtool for controlling the MDI-X (crossover) state of a network port. Most adapters correctly negotiate MDI-X, but some ill-behaved switches have trouble and end up picking the wrong MDI setting, which results in complete loss of link. Usually this error condition can be observed when multiple ethtool -r ethX are required before link is achieved. This patch allows the user to override the normal "auto" setting and force the crossover state to on or off. The set will fail if the driver doesn't support the get, as suggested by Ben Hutchings. setting MDI not supported In addition the do_gset output was changed slightly to report the value set by the user (when the driver supports the set) old: MDI-X: on new: MDI-X: on (auto) or MDI-X: on (forced) usage is ethtool -s eth0 mdix [auto|on|off] Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> CC: Ben Hutchings <bhutchings@solarflare.com> Tested-by: Aaron Brown aaron.f.brown@intel.com Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-07-16Don't trust drivers to null-terminate stringsBen Hutchings1-15/+23
Some drivers have been seen to fill all bytes of ethtool_drvinfo::fw_version without including a null terminator, which effectively concatenates the following bytes to the string. We've already dealt with a similar problem in dump_stats() (commit 7764430a139e4a089127f5616b0d56f497be1036). Try to cover all the remaining string fields: - In dump_drvinfo(), limit the length using printf() modifiers - Add an option to get_stringset() to null-terminate all strings - Change all callers except dump_stats() to set that option Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-07-16Ethtool: Add EEE supportYuval Mintz1-20/+116
This patch adds 2 new ethtool commands which can be used to manipulate network interfaces' support in EEE.

2012-07-16Fix reporting of VLAN tag offload flags on Linux < 2.6.37Ben Hutchings1-0/+41
These kernel versions implement ETHTOOL_GFLAGS but do not include the flags for VLAN tag offload (and do not implement ETHTOOL_GFEATURES). Since the VLAN tag offload features were already defined and implemented by many drivers, we shouldn't assume they are off. Instead, since these feature flag values were stable, read them from sysfs. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-07-16Remove bogus error message when changing offload settings on Linux < 2.6.39Ben Hutchings1-27/+33

2012-06-13ethtool: Handle more errors when getting feature namesBen Hutchings1-2/+10
'ethtool -k eth0' generally works for unprivileged users, but in some kernel versions ETHTOOL_GSSET_INFO wrongly returns -EPERM. We need to fall back to the old offload operations in this case. Also, if we get some other error code, report that before exiting. Add regression test cases covering this and some other operations that may fail (which were already handled correctly).

2012-06-02Change -k/-K options to use ETHTOOL_{G,S}FEATURESBen Hutchings1-92/+356
Rewrite the offload get and set functions to use the generic features API where available, while maintaining a similar output format. Add the long options --show-features and --features as additional aliases for -k and -K. Where there is exactly one named feature corresponding to an old offload name, show the feature using the old offload name. Where there are multiple features corresponding to an old offload name, show the features as a group, indented underneath it. Add some test cases to check that this works properly with or without the generic features API. (These may well be insufficient.) Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-06-02Report when offload feature changes are not exactly as requestedBen Hutchings1-20/+45
When an offload feature is enabled or disabled, this can change the state of other features that depend on it, or may itself be deferred if it depends on a feature that is disabled. Report when this happens, and fail if no offload features could be changed. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-06-02Regularise offload feature settingsBen Hutchings1-202/+89
This is partly preparation for use of the new net device features API, but is useful in its own right. Replace repetitive code for getting/setting offload flags with data- driven loops. This changes error messages to use the same long names for offload flags as in dump_offload(), and changes various exit codes to 1. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-01-21Merge RX NFC optionsBen Hutchings1-102/+76
Santwona Behera originally intended to extend the -n and -N options to cover querying and setting rules as well as flow hash options. However, his patch fell between the cracks and the ethtool utility got n-tuple support first, using the -u and -U options. When RX NFC rule support was finally added I insisted that it should not require different command syntax, so rules must be accessed through these options. The sets of valid argument lists following the -n and -u options are still non-overlapping, and similarly for the -N and -U options. Since the top level argument parser now supports arbitrary numbers of option aliases, we can merge these pairs together and achieve the original intent. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-01-20Move '--flash' down the list of optionsBen Hutchings1-3/+3
It doesn't make sense to to list it between the two RX NFC options in the online help. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-01-12rxclass: Use RX_CLS_LOC_{ANY,SPECIAL} in place of RX_CLS_LOC_UNSPECBen Hutchings1-1/+1
The macro RX_CLS_LOC_ANY is now defined in ethtool(-copy).h with the same intended semantics and same value as RX_CLS_LOC_UNSPEC. Change some equality tests to check for the flag RX_CLS_LOC_SPECIAL, to allow for future support of other special location value. Remove the special case for RX_CLS_LOC_UNSPEC in rxclass_print_nfc_rule(), since it is dead code. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2011-11-03Rearrange definitions and remove unnecessary forward declarationsBen Hutchings1-243/+204
Most functions in ethtool.c are defined before use. The major exception is that the args array refers to a large number of functions defined after it. Move the args array and show_usage() functions down, and move a few other functions up. This leaves just one forward declaration in ethtool.c, which is unavoidable because show_usage() and args refer to each other. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

cmdline_msglvl is used both in do_gset() and do_sset(), but it refers to variables only used in do_sset(). I want to get rid of the global variables without duplicating the flag definitions. So separate out the flag definitions into a new structure and generate cmdline_msglvl from that at run-time. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2011-11-03Support arbitrary numbers of option names for each modeBen Hutchings1-52/+58
Instead of supporting a single short and long option for each mode, take a string of options separated by "|" (matching the way they are displayed in online help). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2011-11-03Move argument parsing to sub-command functionsBen Hutchings1-606/+382
Instead of doing most of the argument parsing in parse_cmdline(), find the sub-command and (if required) the device name in main() and do the rest in the sub-command handler function. Pass argc and argp around in struct cmd_context. This also tightens up argument parsing slightly: extraneous or missing arguments will now result in an error in a few cases where they were previously ignored. All test cases now pass. Replace sub-command dispatch in doit() with a function pointer in struct option. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
