ethtool: use ethnl_parse_header_dev_put()

2021-12-15T10:27:47+00:00

It seems I missed that most ethnl_parse_header_dev_get() callers declare an on-stack struct ethnl_req_info, and that they simply call dev_put(req_info.dev) when about to return. Add ethnl_parse_header_dev_put() helper to properly untrack reference taken by ethnl_parse_header_dev_get().

ethtool: link up ethnl_header_policy as a nested policy

2020-10-06T13:25:55+00:00

To get the most out of parsing by the core, and to allow dumping full policies we need to specify which policy applies to nested attrs. For headers it's ethnl_header_policy. $ sed -i 's@$ETHTOOL_A_.*HEADER\].*=$ { .type = NLA_NESTED },@\1\n\t\tNLA_POLICY_NESTED(ethnl_header_policy),@' net/ethtool/* Signed-off-by: Jakub Kicinski Signed-off-by: David S.

ethtool: trim policy tables

2020-10-06T13:25:55+00:00

Since ethtool uses strict attribute validation there's no need to initialize all attributes in policy tables. 0 is NLA_UNSPEC which is going to be rejected. Remove the NLA_REJECTs. Similarly attributes above maxattrs are rejected, so there's no need to always size the policy tables to ETHTOOL_A_..._MAX. v2: - new patch Suggested-by: Johannes Berg Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

ethtool: wire up set policies to ops

2020-10-06T13:25:55+00:00

Similarly to get commands wire up the policies of set commands to get parsing by the core and policy dumps. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

net: ethtool: Remove PHYLIB direct dependency

2020-07-07T22:41:05+00:00

Now that we have introduced ethtool_phy_ops and the PHY library dynamically registers its operations with that function pointer, we can remove the direct PHYLIB dependency in favor of using dynamic operations. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: ethtool: Handle missing cable test TDR parameters

2020-06-24T03:21:01+00:00

A last minute change put the TDR cable test parameters into a nest. The validation is not sufficient, resulting in an oops if the nest is missing. Set default values first, then update them if the nest is provided.

net: ethtool: Allow PHY cable test TDR data to configured

2020-05-27T06:22:21+00:00

Allow the user to configure where on the cable the TDR data should be retrieved, in terms of first and last sample, and the step between samples. Also add the ability to ask for TDR data for just one pair. If this configuration is not provided, it defaults to 1-150m at 1m intervals for all pairs. Signed-off-by: Andrew Lunn v3: Move the TDR configuration into a structure Add a range check on step Use NL_SET_ERR_MSG_ATTR() when appropriate Move TDR configuration into a nest Document attributes in the request Signed-off-by: David S.
