Did you provide by any chance -7 instead of -1 as a value for mlx4_core.ko's
log_num_mgm_entry_size parameter (as recommended by the above
documentation)?
Timothy (CC'ed) reported that -7 does not quite work with the default flow
rules (too many limitations) and results in the above error message. -1
should be used, -7 is only for specific use cases and should probably not
even be documented in this file.
