[dpdk-dev] [PATCH 11/17] net/bnxt: check device is started before flow creation

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

Check device is started before flow creation.
Since the vnic data structures aren't created until device start,
the driver dereferences NULL vnic if flow creation is attempted before
device is started,
