This patch adds generic masks for accessing bits in rdma/wrdma registers. Doing this would simplify the driver and adding capture support would be much simpler. Also there is no point in having same bit masks for bits in both rdma and wrdma registers. This patch also deletes the RDMA specific bit masks and makes the code use the generic bit masks.
