These changes will not affect module operation as yet. They are only to get some structs and enums in place for use by subsequent patches (making those smaller). Added here: * sriov state structs and inlines (mlx4_is_master/slave/mfunc) * comm-channel and vhcr support structures * enum values for new FW and comm-channel virtual commands (i.e., commands, passed via the comm channel to the PF-driver). * prototypes for many command wrapper functions (used by the PF context for processing FW commands passed to it by the VFs). * struct mlx4_eqe is moved from eq.c to mlx4.h (it will be used by other mlx4_core source files).
