Sounds fine to me, something like:

#define IB_RECV_OPT_TCP_CHECKSUM_FAILED 0x00000100
#define IB_RECV_OPT_UDP_CHECKSUM_FAILED 0x00000200
#define IB_RECV_OPT_IP_CHECKSUM_FAILED 0x00000400
#define IB_RECV_OPT_TCP_CHECKSUM_SUCCEEDED 0x00000800
#define IB_RECV_OPT_UDP_CHECKSUM_SUCCEEDED 0x00001000
#define IB_RECV_OPT_IP_CHECKSUM_SUCCEEDED 0x00002000

This aligns with the NDIS_TCP_IP_CHECKSUM_PACKET_INFO definition, so a simple shift/mask of the receive options would do.
