mrg | remove __packed attribute from struct ieee80211_radiotap_header
and all the structures that include it.
this should not change anything while avoiding packed vs alignment
warnings from GCC 8, and potentially pessimised code generation
due to the packed marker (there are no misaligned members, just
that the per-device parts may end unaligned.)
all consumers of these members are done from the properly aligned
packet members directly, or, as a union with a 64 byte member,
also properly aligned. codegen didn't appear to change, except
for the definition of sizeof(struct driver_[rt]x_radiotap_header)
in debug info, which is not directly used anywhere.

Use device_suspensor_t instead of struct device_suspensor.
|

| 24-Feb-2010 |
dyoung | A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

Forward declare struct bpf_if and use that as the type for bpf_if

| 1.34 |
| 08-Jan-2010 |
dyoung | Expand PMF_FN_* macros.
|
| 1.33 |
| 16-Sep-2009 |
dyoung | In pmf(9), improve the implementation of device self-suspension
and make suspension by self, by drvctl(8), and by ACPI system sleep
play nice together. Start solidifying some temporary API changes.
1. Extract a new header file, <sys/device_if.h>, from <sys/device.h> and
#include it from <sys/pmf.h> instead of <sys/device.h> to break the
circular dependency between <sys/device.h> and <sys/pmf.h>.
2. Introduce pmf_qual_t, an aggregate of qualifications on a PMF
suspend/resume call. Start to replace instances of PMF_FN_PROTO,
PMF_FN_ARGS, et cetera, with a pmf_qual_t.
3. Introduce the notion of a "suspensor," an entity that holds a
device in suspension. More than one suspensor may hold a device
at once. A device stays suspended as long as at least one
suspensor holds it. A device resumes when the last suspensor
releases it.
Currently, the kernel defines three suspensors,
3a the system-suspensor: for system suspension, initiated
by 'sysctl -w machdep.sleep_state=3', by lid closure, by
power-button press, et cetera,
3b the drvctl-suspensor: for device suspension by /dev/drvctl
ioctl, e.g., drvctl -S sip0.
3c the system self-suspensor: for device drivers that suspend
themselves and their children. Several drivers for network
interfaces put the network device to sleep while it is not
administratively up, that is, after the kernel calls if_stop(,
1). The self-suspensor should not be used directly. See
the description of suspensor delegates, below.
A suspensor can have one or more "delegates". A suspensor can
release devices that its delegates hold suspended. Right now,
only the system self-suspensor has delegates. For each device
that a self-suspending driver attaches, it creates the device's
self-suspensor, a delegate of the system self-suspensor.
Suspensors stop a system-wide suspend/resume cycle from waking
devices that the operator put to sleep with drvctl before the cycle.
They also help self-suspension to work more simply, safely, and in
accord with expectations.
4. Add the notion of device activation level, devact_level_t,
and a routine for checking the current activation level,
device_activation(). Current activation levels are DEVACT_LEVEL_BUS,
DEVACT_LEVEL_DRIVER, and DEVACT_LEVEL_CLASS, which respectively
indicate that the device's bus is active, that the bus and device are
active, and that the bus, device, and the functions of the device's
class (network, audio) are active.
Suspend/resume calls can be qualified with a devact_level_t.
The power-management framework treats a devact_level_t that
qualifies a device suspension as the device's current activation
level; it only runs hooks to reduce the activation level from
the presumed current level to the fully suspended state. The
framework treats a devact_level_t qualifying device resumption
as the target activation level; it only runs hooks to raise the
activation level to the target.
5. Use pmf_qual_t, devact_level_t, and self-suspensors in several
drivers.
6. Temporarily add an unused power-management workqueue that I will
remove or replace, soon.

dyoung | Experimental support for fragmentation and RTS/CTS.
Delete unused atw_voodoo and constants.
Export Tx/Rx statistics with evcnt(9).
Correct the Short Inter-Frame Space (SIFS) that we write to ADM8211's
registers; I do not recall if that corrected the SIFS that I observed
"on the air." Use the constant IEEE80211_DUR_DS_EIFS to configure
the ADM8211's EIFS, instead of writing the same "magic" number,
0x64, that my reference driver wrote.
Do not clear OACTIVE in atw_init(), because atw_stop() cleared it
previously by calling atw_txdrain().
Use the net80211 short-preamble flag and instead of ATW_SHPREAMBLE.
Add an ADM8211 workaround from the reference driver, atw_workaround1(),
but don't compile it right now.
In at_intr(), don't stop processing the interrupt status after
restarting the receive ring, but process Tx interrupt status. If
a packet's Tx lifetime is exceeded, reinitialize the device to get
packets moving again. If the Tx FIFO underflows, restart the
transmitter, not the receiver!
Avoid losing synchronization with the Rx ring by replicating one
of Charles Hannum's fixes to rtw(4) here: receiving a management
packet may, as a side-effect, reset the Rx ring, so refer to the
softc's Rx ring pointer, sc_rxptr, every time through the loop in
atw_rxintr(), instead of refering to a pointer on the stack, i.
Re-synchronize DMA after reading the OWN bit on an Rx/Tx descriptor.
XXX This needs more work.
Reset sc_tx_timer as Tx descriptors are reclaimed from the device.
Shorten staircases in atw_watchdog().
Remove from softc an unused member, sc_intr_ack.

Count received frames, Rx PLCP errors, Rx FCS (CRC32) errors, and
Rx ICV errors using evcnt(9).
In promiscuous mode, and when scanning (hmm), ask the NIC for bad
packets (e.g., those that do not pass CRC32). Pass bad packets to
radiotap listeners. Pass packets to radiotap listeners before
stripping FCS. Re-order operations in atw_rxintr() to accomplish
all of this without passing bad packets up to net80211.
Set radiotap channel once in atw_tune() instead of in atw_rxintr().
Fix an endianness bug: it_len is little-endian, but bpf_mtap2()'s
argument needs to be in host order.

Per discussion on tech-kern and tech-userlevel, move the bit-twiddling
macros, __BIT, __BITS, SHIFTIN, SHIFTOUT, and __arraycount() from
lib/libkern/libkern.h to sys/cdefs.h. Add a __-prefix to SHIFTIN
and SHIFTOUT, and add a manual page for the bit-twiddling macros,
bits(3).
Make the __BIT and __BITS macros "widthless," as best I can, by
changing their type to uintmax_t from uint32_t. XXX The manual
page lags this change by a bit.
Define __PRIxBIT and __PRIxBITS printf(3) format strings.

|
| 1.20 |
| 08-Mar-2006 |
dyoung | Move my bit-twiddling macros to libkern.h from my drivers, where
I had duplicated them. Improve the macros' names. Simplify their
implementation.
A brief description of each macro is below.
BIT(n): Return a bitmask with bit m set, where the least
significant bit is bit 0.
BITS(m, n): Return a bitmask with bits m through n, inclusive,
set. It does not matter whether m>n or m<=n.
The least significant bit is bit 0.
A "bitfield" is a span of consecutive bits defined by a
bitmask, where 1s select the bits in the bitfield. SHIFTIN,
SHIFTOUT, and SHIFTOUT_MASK help read and write bitfields
from device registers.
SHIFTIN(v, mask): Left-shift bits `v' into the bitfield
defined by `mask', and return them. No
side-effects.
SHIFTOUT(v, mask): Extract and return the bitfield selected
by `mask' from `v', right-shifting the
bits so that the rightmost selected bit
is at bit 0. No side-effects.
SHIFTOUT_MASK(mask): Right-shift the bits in `mask' so that
the rightmost non-zero bit is at bit
0. This is useful for finding the
greatest unsigned value that a bitfield
can hold. No side-effects. Note that
SHIFTOUT_MASK(m) = SHIFTOUT(m, m).
Examples:
/*

#define RF3000_GAINCTL 0x11 /* TX variable gain control */
#define RF3000_GAINCTL_TXVGC_MASK BITS(7, 2)

/*
* Shift the transmit power into the transmit-power field of the

*/

#define ATW_RXSTAT_DA0 BIT(16) /* DA bit 0, group address */
#define ATW_RXSTAT_RXDR_MASK BITS(15,12) /* RX data rate */
#define ATW_RXSTAT_FL_MASK BITS(11,0) /* RX frame length, last
* descriptor only
