197ff3ac2f devip: if the server does not support TCP ws option, disable window scaling (thanks joe9)
if the server responds without a window scale option in
its syn-ack, disable window scaling alltogether as both
sides need to understand the option.

d7aa56c073 upas/fs: remove read timeout via alarm(2) in pop3resp
The alarm note is not handled by upas/fs, so if and when it did fire,
the pop3 client process would terminate rendering the entire fs
unresponsive.

c881e33e8e bcm, bcm64: fix cache operations for dma and emmc
always clean AND invalidate caches before dma read,
never just invalidate as the buffer might not be
aligned to cache lines...

we have to invalidate caches again *AFTER* the dma
read has completed. the processor can bring in data
speculatively into the cache while the dma in in
flight.

needed anymore.

avoid trashing the following atag when zero
terminating the cmdline string.

157d7ebdbd devip: do not lock selftab in ipselftabread(), remove unused fields from Ipself
the Ipselftab is designed to not require locking on read
operation. locking the selftab in ipselftabread() risks
deadlock when accessing the user buffer creates a fault.

remove unused fields from the Ipself struct.

333c320204 devip: reset speed and delay on bind, adjust burst on mtu change, ifc->m nil check, consistent error strings
initialize the rate limits when the device gets
bound, not when it is created. so that the
rate limtis get reset to default when the ifc
is reused.

adjust the burst delay when the mtu is changed.
this is to make sure that we allow at least one
full sized packet burst.

make a local copy of ifc->m before doing nil
check as it can change under us when we do
not have the ifc locked.

specify Ebound[] and Eunbound[] error strings
and use them consistently.

3a0d5f41a8 devip: remove unused c->car qlock, avoid potential deadlock in ipifcregisterproxy()
remove references to the unused Conv.car qlock.

ipifcregisterproxy() is called with the proxy
ifc wlock'd, which means we cannot acquire the
rwlock of the interfaces that will proxy for us
because it is allowed to rlock() multiple ifc's
in any order. to get arround this, we use canrlock()
and skip the interface when we cannot acquire the
lock.

the ifc should get wlock'd only when we are about
to modify the ifc or its lifc chain. that is when
adding or removing addresses. wlock is not required
when we addresses to the selfcache, which has its
own qlock.

a25819c43a devip: avoid media bind/unbind kproc reader startup race, simplify etherbind
mark reader process pointers with (void*)-1 to mean
not started yet. this avoids the race condition when
media unbind happens before the kproc has set its
Proc* pointer. then we would not post the note and
the reader would continue running after unbind.

etherbind can be simplified by reading the #lX/addr
file to get the mac address, avoiding the temporary
buffer.

3a4a3faf29 nusb/usbd: work around devices that ignore the high byte of wLength in control transfer reads
there appear to be devices out there such as Realtek RTL2838UHIDIR
SDR that do not process control transfers correctly, ignoring the
high byte of the wLength field. to work around this, we specify an
odd number of bytes for read sizes >= 256 which keeps the low byte
0xFF.

4d96c40a47 usbdwc: enable Slowbuilkin workarround, improve split transaction timing, handle erroring sleep(), debugging
i'v been seeing the error condition described above in the
Slowbulkin comment. so i'm enabling the work arround which
seems to fix the lockup.

in the split transaction case where we want to start the
transaction at frame start, acquire the ctlr lock *before*
checking if we are in the right frame number. so the start
will happen atomically. checking the software ctlr->sofchan
instead of checking the interrupt mask register seems to
be quicker.

setting the haint mask bit for the chan under ctlr lock
in chanio() instead of chanwait() avoids needing to acquire
the ctlr lock twice.

mask wakechan bits with busychan bitmap in interrupt handlers
so we will not try to wake up released chans by accident.

sleep() and tsleep() might get interrupted so we have to
release the split qlock in the split transaction case and
in all cases, make sure to halt the channel before release.

add some common debug functions to dump channel and controller
registers.
