  Modified files:
    sys/dev/msk          if_msk.c 
  Log:
  Add legacy interrupt handler which would be more appropriate for
  interrupt that is shared with other devices(e.g. USB) in system and
  provide a new tunable "hw.msk.legacy_intr" to activate the legacy
  interrupt handler. Setting the tunable automatically disables MSI
  for msk(4). Previously msk(4) used adoptive polling with taskqueue(9)
  as all msk(4) hardwares I know supports MSI. However, there are cases
  that MSI couldn't be used on some hardwares due to bugs in MSI
  implementatins.
