[dpdk-dev] [PATCH 4/4] common/iavf: use BIT() macro for offload/cap bits

[Qi Zhang <qi.z.zhang@intel.com>]

Currently raw hex values are used to define specific bits for each
offload/capability in virtchnl.h. The can and has led to duplicate
defined bits. Fix this by using the BIT() macro so it's
immediately obvious which bits are used/available.
