[dpdk-stable] [PATCH v2 5/7] kni: remove unused PCI info from test and example

[dpdk-stable] [PATCH v2 5/7] kni: remove unused PCI info from test and example

[Chenbo Xia]

PCI device id and address in structure rte_kni_conf are never used
in the test, example and kni library. So remove the related code.

Fixes: ea6b39b5b847 ("kni: remove ethtool support")
Cc: stable@dpdk.org
