everything was broken. strting with hsinit not even chaining
the itd's into a ring. followed by broken buffer pointer pages.
finally, the interrupt handler's read transaction length
calculation was completely bugged, using the *FRAME* index
to access descriptors csw[] fields and not reseting tdi->ndata
thru the loop.
minor stuff:
iso->data needs to be freed with ctlr->dmafree()
put ival in iso->ival so ctl message cannot override the endpoints
pollival and screw up deallocation.
we allow devether to create ethernet cards on attach. this is useull
for virtual cards like the sink driver, so we can create a sink
by simply: bind -a '#l2:sink ea=112233445566' /net
the detach routine was never called, so remove it from the few drivers
that attempted to implement it.
the only architecture dependence of devether was enabling interrupts,
which is now done at the end of the driver's reset() function now.
the wifi stack and dummy ethersink also go to port/.
do the IRQ2->IRQ9 hack for pc kernels in intrenabale(), so not
every caller of intrenable() has to be aware of it.
devfs crypto partitions do not support unaligned reads,
so we make a copy of the first in /env/block and then
slice it to find filesystem signatures.
thanks mykhal for reporting the issue.
the td index "x" was incremented twice, once in for loop
and in the body expression. so r->rp only got updated
every second completion. this is wrong, but harmless.
flushing tlb once the index wraps arround is not enougth
as in use pte's can be speculatively loaded. so instead
use invlpg() and explicitely invalidate the tlb of the
page mapped.
this fixes wired mount cache corruption for reads approaching
2MB which is the size of the KMAP window.
invlpg() was broken, using wrong operand type.
remove myaddr() function and replace with myip() function
that receives binary ip address. and don't use string
comparsion for ip addresses... parse and then ipcmp().
for sanity reasons, normalize ip address strings and
reject unparsable ones. done by calling ipalookup()
with a binary ip address.
