Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same

Sockets representing the TCP endpoints for iWARP connections are
allocated by the ibcore module. Before this revision they were closed
either by the ibcore module or the iw_cxgbe hardware driver depending on
the state transitions during connection teardown. This is error prone
and there were cases where both iw_cxgbe and ibcore closed the socket
leading to double-free panics. The fix is to let ibcore close the
sockets it creates and never do it in the driver.
- Use sodisconnect instead of soclose (preceded by solinger = 0) in the
driver to tear down an RDMA connection abruptly. This does what's
intended without releasing the socket's fd reference.
- Close the socket in ibcore when the iWARP iw_cm_id is destroyed. This
works for all kinds of sockets: clients that initiate connections,
listeners, and sockets accepted off of listeners.

SBP-2 specification defined maximum CDB length as 12 bytes. Newer SBP-3
specification allows CDB of any size, but this driver is too old. Proper
solution would be to look on maximal ORB size supported by the target.

During acpi_cmbat_attach() the acpi_cmbat_init_battery() notification
handler is registered. It has been observed this notification handler
can be called instantly, before the attach routine has returned. In
the notification handler there is a call to device_is_attached() which
returns false. Because the softc is set we know an attach is in
progress and the fix is simply to wait and try again in this case.

- Use ni_txparms directly instead of calculating them manually every time
- Move M_EAPOL flag check upper; otherwise it may be skipped due to
'ucastrate' / 'mcastrate' check
- Use 'mgtrate' for control frames too (see ifconfig(8), mgtrate parameter)
- Add few more M_EAPOL checks where it was missing (zyd(4), ural(4),
urtw(4))
- Few unrelated cleanups

pcib_request_feature allows drivers to request the firmware (ACPI)
release certain features it may be using. ACPI normally manages things
like hot plug, advanced error reporting and other features until the

On Core2 and older Intel CPUs, where TSC stops in C2, system does not
allow C2 entrance if timecounter hardware is TSC. This is done by
tc_windup() which tests for TC_FLAGS_C2STOP flag of the new
timecounter and increases cpu_disable_c2_sleep if flag is set. Right
now init_TSC_tc() only sets the flag if cpu_deepest_sleep >= 2, but
TSC is initialized too early for this variable to be set by
acpi_cpu.c.
There is no reason to require that ACPI reported C2 and deeper states
to set TC_FLAGS_C2STOP, so remove cpu_deepest_sleep test from
init_TSC_tc() condition. And since this is the only use of the
variable, remove it at all.
