[dpdk-dev] [RFC PATCH 4/4] Update the rte_ethdev.[ch] files for the new device generic changes.

Wed Apr 8 22:58:40 CEST 2015
rte_ethdev.c (main points):
- Collect up the globals and static variables in the file into a new rte_eth_globals structure.
- Update the global references to use the new global structure
- Move parts of the callback routines into eal_common_device.c to all other device a common routine
- Moved the debug macros PROC_PRIMARY_OR_ERR_RET, PROC_PRIMARY_OR_RET, FUNC_PTR_OR_ERR_RET and
FUNC_PTR_OR_RET into the rte_common_device.h as a common macro between devices.
rte_ethdev.h (main points):
- Replace the first couple members in rte_eth_dev_info to commmon macro
- Remove rte_eth_dev_cb_list define an use common rte_dev_cb_list instead
- Move eth_[rt]x_burst_t to dev_[rt]x_burst_t in eal_common_device.h
- Move rte_[rt]x_callback typedefs to eal_common_device.h as they are generic
- Move rte_eth_dev_type to eal_common_device.h and rename to rte_dev_type
- Move rte_eth_event_type to eal_common_device.h and rename to rte_dev_event_type
- Replace the content of rte_eth_dev with macro RTE_COMMON_DEV in eal_common_device.h
Replace part of the content of rte_eth_dev_data with macro RTE_COMMON_DEV_DATA
Replace part of the content of rte_eth_dev_info with macro RTE_COMMON_DEV_INFO
- Added the new global device structure to hold device local data instead of globals.
- Some of the simple functions rte_eth_dev_count and others now call rte_dev_count() via macro.
The eal_common_device.c and rte_common_device.h could merged into eal_common_dev.c and
rte_common_dev.h, which is not done here as to not effect those files.
