[for-next 02/15] net/mlx5: E-Switch, Move representors definition to a global scope

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mark Bloch <markb@xxxxxxxxxxxx>

In preparation for IB representors, move representors structs to a global
scope, also expose functions needed for registration, unregistration,
eswitch mode and creating a flow rule to direct traffic from SQs to the
right VF.
