Subject: [PATCH rdma-next 0/7] Add other eswitch support

From: Patrisious Haddad <phaddad@...dia.com>

>From Patrisious:
When the device in switchdev mode, the RDMA device manages all the
vports which belong to its representors, which can lead to a situation
where the PF that is used to manage the RDMA device isn't the native PF
of some of the vports it manages.

Add infrastructure to allow the master PF to manage all the hardware
resources for the vports under its management.
Whereas currently the only such resource is RDMA TRANSPORT steering
domains.

That is done by adding new FW argument other_eswitch which is passed by
the driver to the FW to allow the master PF to properly manage vports
belonging to other native PF.
