[dpdk-users] i40e Requested device cannot be used

[Aaron Hughes]

Hi,

I'm trying to use testpmd with an XL710 on Redhat 7.5 but I'm getting the
requested device cannot be used error.  I've seen similar errors on the
mailing list but haven't found a solution.

0000:af:00.0 already bound to driver igb_uio, skipping
