Before this patch during either switchdev or legacy mode enablement we
cleared the mac address of vports between changes. This change allows us
to preserve the vports mac address between eswitch mode changes.
Vports hold information for VFs/SFs such as the permanent mac address.
VF/SF mac can be set either by iproute vf interface or devlink function
interface. For no obvious reason we reset it to 0 on switchdev/legacy
mode changes, this patch is fixing that, to align with other vport
information that are never reset, e.g GUID,mtu,promisc mode, etc ..

These functions are for query/set by vport, there was an underlying
assumption that vport was equal to function ID. That's not the case for
EC VF functions. Set the ec_vf_function bit accordingly.

net/mlx5: E-Switch, Prepare to return total vports from eswitch struct2021-04-24T07:58:43+00:00Parav Panditparav@nvidia.com2021-03-02T12:10:49+00:00urn:sha1:9f8c7100c8f9879b7e972205cd1f33f0bc1cc8cb
Total vports are already stored during eswitch initialization. Instead
of calculating everytime, read directly from eswitch.
Additionally, host PF's SF vport information is available using
QUERY_HCA_CAP command. It is not available through HCA_CAP of the
eswitch manager PF.
Hence, this patch prepares the return total eswitch vport count from the
existing eswitch struct.
This further helps to keep eswitch port counting macros and logic within
eswitch.

net/mlx5: Introduce and use mlx5_eswitch_get_total_vports()2019-07-03T19:50:42+00:00Parav Panditparav@mellanox.com2019-05-15T05:04:27+00:00urn:sha1:2752b823169b216db142c4466b43269281962dcf
Instead MLX5_TOTAL_VPORTS, use mlx5_eswitch_get_total_vports().
mlx5_eswitch_get_total_vports() in subsequent patch accounts for SF
vports as well.
Expanding MLX5_TOTAL_VPORTS macro would require exposing SF internals to
more generic vport.h header file. Such exposure is not desired.
Hence a mlx5_eswitch_get_total_vports() is introduced.
Given that mlx5_eswitch_get_total_vports() API wants to work on const
mlx5_core_dev*, change its helper functions also to accept const *dev.
