devlink: allow to fillup eswitch attrs even if mode_get op does not exist

2017-02-10T19:43:00Z

Even when mode_get op is not present, other eswitch attrs need to be filled-up. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: use nla_put_failure goto label instead of out

2017-02-10T19:43:00Z

Be aligned with the rest of the code and use label named nla_put_failure. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: rename devlink_eswitch_fill to devlink_nl_eswitch_fill

2017-02-10T19:43:00Z

Be aligned with the rest of the file and name the helper function accordingly. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: fix the name of eswitch commands

2017-02-10T19:43:00Z

The eswitch_[gs]et command is supposed to be similar to port_[gs]et command - for multiple eswitch attributes. However, when it was introduced by 08f4b5918b2d ("net/devlink: Add E-Switch mode control") it was wrongly named with the word "mode" in it. So fix this now, make the oririnal enum value existing but obsolete. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: Add E-Switch inline mode control

2016-11-24T21:01:14Z

Some HWs need the VF driver to put part of the packet headers on the TX descriptor so the e-switch can do proper matching and steering. The supported modes: none, link, network, transport. Signed-off-by: Roi Dayan Reviewed-by: Or Gerlitz Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

genetlink: mark families as __ro_after_init

2016-10-27T20:16:09Z

Now genl_register_family() is the only thing (other than the users themselves, perhaps, but I didn't find any doing that) writing to the family struct. In all families that I found, genl_register_family() is only called from __init functions (some indirectly, in which case I've add __init annotations to clarifly things), so all can actually be marked __ro_after_init. This protects the data structure from accidental corruption. Signed-off-by: Johannes Berg Signed-off-by: David S. Miller

genetlink: statically initialize families

2016-10-27T20:16:09Z

Instead of providing macros/inline functions to initialize the families, make all users initialize them statically and get rid of the macros. This reduces the kernel code size by about 1.6k on x86-64 (with allyesconfig). Signed-off-by: Johannes Berg Signed-off-by: David S. Miller

genetlink: no longer support using static family IDs

2016-10-27T20:16:09Z

Static family IDs have never really been used, the only use case was the workaround I introduced for those users that assumed their family ID was also their multicast group ID. Additionally, because static family IDs would never be reserved by the generic netlink code, using a relatively low ID would only work for built-in families that can be registered immediately after generic netlink is started, which is basically only the control family (apart from the workaround code, which I also had to add code for so it would reserve those IDs) Thus, anything other than GENL_ID_GENERATE is flawed and luckily not used except in the cases I mentioned. Move those workarounds into a few lines of code, and then get rid of GENL_ID_GENERATE entirely, making it more robust. Signed-off-by: Johannes Berg Signed-off-by: David S. Miller

devlink: Prevent port_type_set() callback when it's not needed

2016-10-26T21:30:32Z

When a port_type_set() is been called and the new port type set is the same as the old one, just return success. Signed-off-by: Elad Raz Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: add hardware messages tracing facility
