[dpdk-dev] [PATCH v2 02/18] eal: remove generic devtype
Gaetan Rivet

Thu Oct 12 10:21:09 CEST 2017
The devtype is now entirely defined by the device bus. As such, it is
already characterized by the bus identifier within an rte_devargs.
The rte_devtype enum can disappear, along with crutches added during
this transition.
rte_eal_devargs_type_count becomes useless and is removed.
