Subject: net/hns3: check setting VF PCI bus return value
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7ac3ae7649985c54a10f6904c298918e00a07e92;p=dpdk.git

net/hns3: check setting VF PCI bus return value

Currently hns3vf_reinit_dev only judge whether the return value of
setting PCI bus function is not 0, while it will return a negative
value when execute failed.
