[dpdk-dev] net/i40e: avoid PCI probing failure when using bogus sfp
Checks
Commit Message
When a port is using a bogus SFP, the PCI probing returns an error,
preventing to register a portid.
To give a better chance to the applications to retry after the SFP is
changed, move this check in eth_i40e_dev_configure(), so that only a
port reconfiguration is needed to retry.
