Hi Bruce,

I was seeing a similar problem on my system when attaching a virtual functi=
on port.

testpmd> port attach 0000:06:10.0=20
Attaching a new port...
EAL: PCI device 0000:06:10.0 on NUMA socket -1
EAL:   probe driver: 8086:10ed rte_ixgbevf_pmd
EAL:   PCI memory mapped at 0x10000
EAL: pci_map_resource(): cannot mmap(27, 0x14000, 0x4000, 0x1000): Invalid =
argument (0xffffffffffffffff)
EAL: Requested device 0000:06:10.0 cannot be used
EAL: Driver, cannot attach the device

This patch seems to solve the problem.

Regards,

Bernard.
