jhb 47352638fe Add a facility for transmitting "raw" work requests on regular NIC queues.
- Use PH_loc.eight[1] as a general 'cflags' (Chelsio flags) field to
  describe properties of a queued packet.  The MC_RAW_WR flag
  indicates an mbuf holding a raw work request.  mbuf_cflags() returns
  the current flags.
- Raw work request mbufs are allocated via alloc_wr_mbuf() which will
  allocate a single contiguous range to hold the mbuf data.  The
  consumer can use mtod() to obtain the start of the work request and
  write the required work request in the buffer.  The mbuf can then be
  enqueued directly to the txq via mp_ring_enqueue().
- Since raw work requests might potentially send arbitrary work
  requests, only set the EQUIQ and EQUEQ bits on work requests that
  support them such as the normal tunneled Ethernet packet work
  requests.
