This will get some small fixes for various low-level driver issues:

Chien Tung (1):
      MAINTAINERS: Update NetEffect (iw_nes) entry

Joachim Fenkes (1):
      IB/ehca: Reject send WRs only for RESET, INIT and RTR state

Ralph Campbell (2):
      IB/ipath: Fix device capability flags
      IB/ipath: Fix SM trap forwarding

Roland Dreier (1):
      IB/ipath: Avoid test_bit() on u64 SDMA status value
