support FreeBSD.
1) Timeout ioctl command timeouts.
Do not reset the controller if ioctl command completed
successfully.
2) Remove G66_WORKAROUND code (this bug never shipped).
3) Remove unnecessary interrupt lock (intr_lock).
4) Timeout firmware handshake for PChip reset (don't wait forever).
5) Handle interrupts inline.
6) Unmask command interrupt ONLY when adding a command to the pending
queue.
7) Mask command interrupt ONLY after removing the last command from
the pending queue.
8) Remove TW_OSLI_DEFERRED_INTR_USED code.
9) Replace controller "state" with separate data fields to avoid races:
TW_CLI_CTLR_STATE_ACTIVE ctlr->active
TW_CLI_CTLR_STATE_INTR_ENABLED ctlr->interrupts_enabled
TW_CLI_CTLR_STATE_INTERNAL_REQ_BUSY ctlr->internal_req_busy
TW_CLI_CTLR_STATE_GET_MORE_AENS ctlr->get_more_aens
TW_CLI_CTLR_STATE_RESET_IN_PROGRESS ctlr->reset_in_progress
TW_CLI_CTLR_STATE_RESET_PHASE1_IN_PROGRESS ctlr->reset_phase1_in_progress
10) Fix "req" leak in twa_action() when simq is frozen and req is NOT
null.
11) Replace softc "state" with separate data fields to avoid races:
TW_OSLI_CTLR_STATE_OPEN sc->open
TW_OSLI_CTLR_STATE_SIMQ_FROZEN sc->simq_frozen
12) Fix reference to TW_OSLI_REQ_FLAGS_IN_PROGRESS in
tw_osl_complete_passthru()
13) Use correct CAM status values.
Change CAM_REQ_CMP_ERR to CAM_REQ_INVALID.
Remove use of CAM_RELEASE_SIMQ for physical data addresses.
14) Do not freeze/ release the simq with non I/O commands.
When it is appropriate to temporarily freeze the simq with an I/O
command use:
xpt_freeze_simq(sim, 1);
ccb->ccb_h.status |= CAM_RELEASE_SIMQ;
otherwise use:
xpt_freeze_simq(sim, 1);
xpt_release_simq(sim, 1);
