[dpdk-dev] [PATCH] vmxnet3: fixed segfault when initializing vmxnet3 pmd on linux platform

[Daniel Kan]

The vmxnet3 PCI hardware resources were never memory mapped when RE_EAL_UNBIND_PORTS is not defined.
Specifically, pci_dev->mem_resource is not mapped. The fix is to always set drv_flags with RTE_PCI_DRV_NEED_IGU for vmxnet3. This ensures pci_uio_map_resource() is called.
