transaction to 8. value 32 triggers occational watchdog() Tx
timeout when higher system load. This symptom is observed in
ipforwarding across two PCI devices case so far, and it remains
unidentified what really happens for Tx DMA activity. 16 seems
ok, 8 is conservative and heuristic value. may need more adjustment
work in other parts.

sysmon_envsys_create() and sysmon_envsys_destroy() were added to
create/destroy sysmon_envsys objects (and its TAILQ/LIST for sensors/events).
sysmon_envsys_sensor_attach() and sysmon_envsys_sensor_detach() were
added to attach/detach sensors to a specified sysmon_envsys device.
The events framework is now per device and configurable via the
ENVSYS_SETDICTIONARY ioctl or /etc/envsys.conf and envstat(8).
Update all users and documentation to reflect these changes.
Do not alias the Rx descriptor word ar_ctl to ar_rssi with a #define.
Instead, call the member ar_ctlrssi.
Convert the ugly macro ATW_RXDESC_INIT() to an inline subroutine,
atw_rxdesc_init().
Do not load an empty IEEE80211_RADIOTAP_FLAGS field into the Tx
radiotap header.
rtw_rxdesc_init: before initializing a Rx descriptor's
control word, synchronize the Rx buffer
rtw_start, be paranoid: set the "NIC owns" bit on a Tx
descriptor dead last. Always reinitialize the "next
Tx descriptor" pointer, just in case it got clobbered
somehow.
Let the compiler decide whether to inline rtw_collect_txring or
not.
- The driver now uses the Super I/O address port as port argument in
the configuration file. The Environmental Controller base address is
fetched by the Super I/O EC LDN configuration registers.
- Invalidate voltage sensors if data returned is 0xff.
- Use the Super I/O Global Configuration Registers Chip ID[12] and Device
Revision to store/print the correct information.
- Use only the Fan Extended Tachometer registers on IT871[68]F for now;
this gives us correct data for IT8705/IT8712F again.
Inspired by the smsc(4) driver. The UPDATING file has been updated to
reflect the rename.
