Add the option to use resources (Tables, Matchers, Actions, etc.)
from one gvmi (AKA ibv_cntext) to other gvmi's.
When specific gvmi allows other to use its resources, steering objects
Will created and used on that gvmi.
It is done by aliases objects that map between local resources to
shared/remote resourses.
That in order to allow sharing between few ports.
Erez Shitrit (6):
mailmap: add new contributors to the list
net/mlx5/hws: add capabilities fields for vhca access
net/mlx5/hws: add vhca identifier ID to the caps
net/mlx5/hws: support shared ibv-context with local one
net/mlx5/hws: support actions while shared resources is used
net/mlx5/hws: add debug details for cross gvmi
Yevgeny Kliteynik (5):
net/mlx5/hws: remove wrong PRM capability macros
net/mlx5/hws: add PRM definitions for cross-vhca capabilities
net/mlx5/hws: read cross-vhca capabilities
net/mlx5/hws: added allow-other-vhca-access command
net/mlx5/hws: added command to create alias objects

The idea is to have a shared ibv_context that all the resources
allocated on it (FT + TIR are exceptions)
When ever a resource created locally an alias object to that resource
allocated and it used in the other context.
The connections between the resources are done according to each type of
the resource, to the original resource or to its alias resource.

TIR/FT actions are different in the context of shared ibv resource, it
created on the local ibv_context and aliased to the shared ibv_context.
Other actions should be created on the shared ibv resource, new flag was
added to indicates where this object came from.

Add the option to use resources (Tables, Matchers, Actions, etc.)
from one gvmi (AKA ibv_cntext) to other gvmi's.
When specific gvmi allows other to use its resources, steering objects
Will created and used on that gvmi.
It is done by aliases objects that map between local resources to
shared/remote resources.
That in order to allow sharing between few ports.
---
Changes from V1:
- remove mailing list patch from that series, it will be sent separately
- remove the duplicated set that sent by mistake
---
Erez Shitrit (5):
net/mlx5/hws: add capabilities fields for vhca access
net/mlx5/hws: add vhca identifier ID to the caps
net/mlx5/hws: support shared ibv-context with local one
net/mlx5/hws: support actions while shared resources is used
net/mlx5/hws: add debug details for cross gvmi
Yevgeny Kliteynik (5):
net/mlx5/hws: remove wrong PRM capability macros
net/mlx5/hws: add PRM definitions for cross-vhca capabilities
net/mlx5/hws: read cross-vhca capabilities
net/mlx5/hws: added allow-other-vhca-access command

The idea is to have a shared ibv_context that all the resources
allocated on it (FT + TIR are exceptions)
When ever a resource created locally an alias object to that resource
allocated and it used in the other context.
The connections between the resources are done according to each type of
the resource, to the original resource or to its alias resource.

TIR/FT actions are different in the context of shared ibv resource, it
created on the local ibv_context and aliased to the shared ibv_context.
Other actions should be created on the shared ibv resource, new flag was
added to indicates where this object came from.
