Merge branch 'implement-dev-info-and-dev-flash-for-line-cards'
Jiri Pirko says:
====================
Implement dev info and dev flash for line cards
This patchset implements two features:
1) "devlink dev info" is exposed for line card (patches 6-9)
2) "devlink dev flash" is implemented for line card gearbox
flashing (patch 10)
For every line card, "a nested" auxiliary device is created which
allows to bind the features mentioned above (patch 4).
The relationship between line card and its auxiliary dev devlink
is carried over extra line card netlink attribute (patches 3 and 5).
The first patch removes devlink_mutex from devlink_register/unregister()
which eliminates possible deadlock during devlink reload command. The
second patchset follows up with putting net pointer check into new
helper.
Examples:
$ devlink lc show pci/0000:01:00.0 lc 1
