Modified files:
sys/dev/usb : xhci.c
Log message:
Add a zero length TD, rather than adding a zero length TRB to the
original TD, when a transfer is a multiple of the max packet size. The
zero length TD will have a NULL xfer pointer.
As a result "NULL xfer pointer" situations become perfectly normal. So
change the log_warnx() that issues that verbiage to a log_debug().
Note that the original transfer will complete and report its result up
the USB stack before the zero length transfer is executed.
Fixes (at least) urtwn(4) interfaces.
