[dpdk-dev] [PATCH v3] net/ixgbe: clean up rte_eth_dev_info_get
Wenzhuo Lu
wenzhuo.lu at intel.com
Tue Feb 7 07:33:26 CET 2017
It's not appropriate to call rte_eth_dev_info_get in PMD,
as rte_eth_dev_info_get need to get info from PMD.
Remove rte_eth_dev_info_get from PMD code and get the
info directly.

v2:
- change is_ixgbe_pmd to is_device_supported to make it more generic.
v3:
- minor change.
