bnx2: Optimize fast-path tx and rx work.
Add hw_tx_cons_ptr and hw_rx_cons_ptr to speed up the retreival of the tx and rx consumer index, since the MSI-X and default status blocks have different structures. Combine status_blk and status_blk_msix into a union. We'll only use one type of status block for each vector. Separate the code to detect more rx and tx work from the code to detect link related work.
