Differences between LAN7800 and LAN7850 from the driver's perspective:
* The LAN7800 muxes EEPROM signals with LEDs, so LED mode needs to be
disabled when reading/writing EEPROM. The EEPROM is not muxed on the
LAN7850.
* The Linux driver enables automatic duplex and speed detection when
there is no EEPROM, for the LAN7800 only. With this FreeBSD driver
LAN7850-based adapters without a configuration EEPROM fail to link
(with or without the automatic duplex and speed detection code), so
I have just followed the example of the Linux driver for now.

to adding the device name to kern.console sysctl, although doing that

for init(8) to recognize them as console devices and to launch getty(8)

that, in turn, is to add such entries to the default ttys(5), so that

The tty layer uses tsw_busy to poll for busy/idle status of the transmitter
hardware during close() and tcdrain(). The ucom layer defines ULSR_TXRDY and
ULSR_TSRE bits for the line status register; when both are set, the
transmitter is idle. Not all chip drivers maintain those bits in the sc_lsr
field, and if the bits never get set the transmitter will always appear
busy, causing hangs in tcdrain().
These changes add a new sc_flag bit, UCOM_FLAG_LSRTXIDLE. When this flag is
set, ucom_busy() uses the lsr bits to return busy vs. idle state, otherwise
it always returns idle (which is effectively what happened before this
change because tsw_busy wasn't implemented).
For the uftdi chip driver, these changes stop masking out the tx idle bits
when processing the status register (because now they're useful), and it
calls ucom_use_lsr_txbits() to indicate the bits are maintained by the
driver and can be used by ucom_busy().

When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().
Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.
While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

net,ethernet/usb,device compatibity strings are FreeBSD custom invention

device tree
- Use -1 value to indicate invalid phandle_t, 0 is valid phandle value and

ignore
There are a variety of more interesting RX statistics that we should
keep track of but we don't. This is a starting point for adding more
information.
Specifically:
* now the RX rate information and some of the packet status is
passed up;
* The 32 bit or 64 bit TSF is passed up;
* the PHY mode is passed up;
* the "I'm decap'ed AMSDU!" state is passed up;
* number of RX chains is bumped to 4.
This is all mostly a placeholder for getting the data into the RX status
before we pass it up to net80211 - unfortunately we don't yet enforce
that drivers provide it, nor do we pass the provided info back up the
stack so anyone can use the data.
We're going to need to use some of this data moving forward.
Notably, now that some hardware can do AMSDU decap for us (the intel iwm
driver can do it when we flip it on; the ath10k port I'm doing does
it for us) then we need to pass it up through the stack so the duplicate
RX sequence numbers and crypto/IV details don't cause the packet to
be dropped and/or counted against a replay counter.
It's also the beginning of being able to do more interesting node
accounting in net80211. Specifically, once drivers start populating
per-packet rate information, AMPDU information, timestamps, etc,
we can start providing histograms of rate-versus-RSSI, account
for receive time spent per node and other such interesting things.
(Note: I'm also hoping to include ranging and RTT information for
future chipset support; and it's likely going to include it in
this kind of fashion.)
Replace various void * / int argument combinations with common structures:
- ieee80211_ratectl_tx_status for *_tx_complete();
- ieee80211_ratectl_tx_stats for *_tx_update();
While here, improve amrr_tx_update() for a bit:
1. In case, if receiver is not known (typical for Ralink USB drivers),
refresh Tx rate for all nodes on the interface.
2. There was a misuse:
- otus(4) sends non-decreasing counters (as originally intended);
- but ural(4), rum(4) and run(4) are using 'read & clear' registers
to obtain statistics for some period of time (and those 'last period'
values are used as arguments for tx_update()). If arguments are not big
enough, they are just discarded after the next call.
Fix: move counting into *_tx_update()
(now otus(4) will zero out all node counters after every tx_update() call)

Use sbintime_t timeouts with precision control to get very accurate
timing. It costs little to always ask for about 1% accuracy, and the
not so new event timer implementation usual delivers that, and when
it can't it gets much closer than our previous coarse timeouts and
buggy simple countdown.
The 2 fastest atkbd repeat rates have periods 34 and 38 msec, and ukbd
pretended to support rates in between these. This requires
sub-microsecond precision and accuracy even to handle the 4 msec
difference very well, but ukbd asked the timeout subsystem for timeouts
of 25 msec and the buggy simple countdown of this gave a a wide range
of precisions and accuracies depending on HZ and other timer
configuration (sometimes better than 25 msec but usually more like 50
msec). We now ask for and usually get precision and accuracy of about
1% for each repeat and much better on average.
The 1% accuracy is overkill. Rounding of 30 cps to 34 msec instead of
33 already gives an error of +2% instead of -1%, and ut AT keyboards on
PS/2 interfaces have similar errors.
A timeout is now scheduled for every keypress and release. This allows
some simplifications that are not done. It allows removing the timeout
scheduling for exiting polled mode where it was unsafe in ddb mode. This
is done. Exiting polled mode had some problems with extra repeats. Now
exiting polled mode lets an extra timeout fire and the state is fudged
so that the timeout handler does very little.
The sc->time_ms variable is unsigned to avoid overflow. Differences of
it need to be signed. Signed comparisons were emulated by testing an
emulated sign bits. This only works easily for '<' comparisonss, but
we now need a '<=' comparison. Change the difference variable to
signed and use a signed comparison. Using unsigned types here didn't
prevent overflow bugs but just reduced them. Overflow occurs with
n repeats at the silly repeat period of [U]INT_MAX / n. The old countdown
had an off by 1 error, and the simplifications would simply count down
1 to 0 and not need to accumulate possibly-large repeat repeats.
kbdcontrol -r fast is documented to give a non-emulated atkbd's fastest
rate of 250.34, but is misimplemented to request this as 0.0. ukbd
supports many nonstandard rates, although it is currently too inaccurate
by a factor of several hundred for non-huge nonstandard rates to be
useful. It mapped 0.0 to 200.0. A repeat delay of 0 means a rate of
infinity which is quite fast, but physical constraints limit this to
a few MHz and the inaccuracies made it almost usable.
Convert 0.0 to the documented 250.34.
Also convert negative args and small args to the 250.34 minimal ones,
like atkbd does. This is for KDSETREPEAT -- the 2 versions of the
deprecated KDSETRAD have bounds checking. Keep not doing any bounds
checking or conversions for upper limits since nonstandard large
delays are useful for testing.
The inaccuracies are dependent on HZ and the timeout implementation.
With the old timeout implementation and HZ = 1000, 200.0 probably
worked better to emulate 250.34 than 250.34 itself. HZ = 100 gives
roundoff errors that accidentally reduce the inaaccuracies, and
event timers reduce the inaccuracies even more, so 200.0 was giving
more like itself (perhaps 215.15 on average but sometimes close to
10 msec repeat which is noticebly too fast). This commit makes 0.0
noticeably too slow, like 250.34 always was.

everything was broken. The cases that I noticed were Ctrl-PrintScreen
not being mapped to the virtual scancode 0x5c (debug) and Pause not being
mapped to the physical/virtual scancode 0x46 (slock).
These keys are the most complicated ones due to kludges to give some
compatibility back to before AT keyboards.
Alt-PrintScreen must pretend to be a separate key from PrintScreen
even at the "raw" level. The (unique) usb code for it is 0x8a and we
just have to map this to our unique virtual scancode 0x54, but we
mapped it first to the internal code 0x7e and then to 0x79 which is a
key on the Japanese 106/109 keyboard. This fix is under the
UKBD_EMULATE_ATASCANCODE option which shouldn't be used for non-AT
keyboards. If it is, then the syscons Japanese keymaps have nothing
of importance for code 0x79 and can easily be changed. 0x54 is also
unimportant in Japanese and US keymaps.
NonAlt-PrintScreen and NonCtl-Pause/Break had many much larger bugs with
smaller compatibility problems from fixing them. The details are too
ugly to give here. Summary of the changed (hex) codes:
K_RAW PrintScreen (Ctl, Shift, Ctl-Shift): E0-2A-E0-37 -> E0-37
K_RAW Alt-PrintScreen (all shift states): 79 -> 54
K_RAW Pause/Break (unshifted, Shift, Alt, Alt-Shift)): E0-46 -> E1-1D-45
K_CODE ALT-PrintScreen (all shift states): 79 -> 54
That is 15 of 32 shift combinations for 2 keys fixed, with 8 easy cases
from the 79 -> 54 remapping.
The difference is only large and with no workaround using a keymap for
for K_RAW, but this affects other modes when ukbd is layered under kbmux

axge_setmulti()/axge_setpromisc() with axge_rxfilter().
Multicast filter programming and promiscuous mode requires
access to a common RX configuration register so there is no need to
use separate functions with added complexity. axge_rxfilter() does
not read back AXGE_RCR register since accessing a register in USB
is too slow and we already have all knowledge of required
configuration. Rebuilding RX filter configuration is simpler and
faster than manipulating every bits after reading back the
register.
Note, axge_rxfilter() does not set RCR_IPE(IP header alignment on
32bit boundary) to disable extra padding bytes insertion. The
extra padding wastes ethernet to USB host bandwidth as well as
complicating RX handling logic. Current USB framework requires
copying RX frames to mbufs so there is no need to worry about
alignment. Previously axge_rx_frame() performed wrong bound check
due to the extra padding and it was broken when RX checksum
offloading is disabled. See added comment in axge_rx_frame () for
actual RX packet layout.
In axge_init(), disable WOL. It's meaningless to enable WOL in

In axge_rxeof(), use properly sized mbuf rather than blindly

For interface teardown we try to do as many of them as we can on

over a higher layer protocol such as IP. In that case the interface
has to go along (or before) the higher layer protocol is shutdown.
Kernel hhooks need to go last on teardown as they may be used at various
higher layers and we cannot remove them before we cleaned up the higher
layers.
For interface teardown there are multiple paths:
(a) a cloned interface is destroyed (inside a VIMAGE or in the base system),
(b) any interface is moved from a virtual network stack to a different
network stack ("vmove"), or (c) a virtual network stack is being shut down.
All code paths go through if_detach_internal() where we, depending on the
vmove flag or the vnet state, make a decision on how much to shut down;
in case we are destroying a VNET the individual protocol layers will
cleanup their own parts thus we cannot do so again for each interface as
we end up with, e.g., double-frees, destroying locks twice or acquiring
already destroyed locks.
When calling into protocol cleanups we equally have to tell them
whether they need to detach upper layer protocols ("ulp") or not
(e.g., in6_ifdetach()).
Provide or enahnce helper functions to do proper cleanup at a protocol
rather than at an interface level.

Currently, in case when npkts >= 2, RSSI and Rx radiotap fields
will be overridden by the next packet. As a result, every packet
from this chain will use the same RSSI / radiotap data.
After this change, RSSI and radiotap structure will be filled
for every frame right before ieee80211_input() call.
Tested with RTL8188EU / RTL8188CUS, STA and MONITOR modes.

An implementation from rum(4) was used (it looks simpler for me).
Will be used for h/w encryption support.

tables. Some drivers needed some slight re-arrangement of declarations
to accommodate this. Change the USB pnp tables slightly to allow
better compatibility with the system by moving linux driver info from
start of each entry to the end. All other PNP tables in the system
have the per-device flags and such at the end of the elements rather
that at the beginning.

from 1500 to 1496 bytes. The MTU should remain at 1500, extending the
frame size as per IEEE 802.3. Adding IFCAP_VLAN_MTU to the
if_capabilities field in the smsc driver solves the problem. The
datasheet for the LAN9512 chip, section 3.2.3 states that the chip
supports the extended frame.
