XXX real fix: make enable/disable for real and invoke them when needed.
XXX This has to wait until the layer 1 <-> layer 2 interface is

transmit jobs. The previous logic occasionally, under heavy
load, would attempt to sync and unload DMA maps that weren't
currently in use, and also occasionally leaked mbufs under
heavy load.
Yay, NFS now works pretty well on my Dreamcast.
it causes assertions to fail in the PCI bounce buffer code. On
other platforms, it causes the address of the next packet to
be mis-calculated, leading to packet loss.
- I tested only ROLAND UM-1 and YAMAHA UX256.
These are not conforming to USB-MIDI spec, however these are
similar to USB-MIDI.
- Since I've not yet seen the "genuine" USB-MIDI device,
I cannot test such devices although I wrote the codes for it.
TODO:
- clean up the codes.
- umidi(4) manpage.
- /dev/rmidi? is working well, but /dev/music seems not working correctly.
- protect the buffer even though ointr occur until exiting
from hw_if->output().
- allow this function to send multiple bytes to hw_if->output()
at the same time. it's necessary for umidi.
This change makes PCMCIA cards work again on my machine.
Unfortunately, some of the DELAY_MS() are called when the current
process is not the cardbus thread, that is, on interrupt contexts.
I confirmed these are actually used in interrupt context and replaced
them with delay()s. However, I haven't confirmed other DELAY_MS()s
are always on the cardbus thread.
This shall be a temporary fix. The driver needs being rewritten
not to use such delay()s, of course.
if we are requested range of multicast address or too many multicast address,
program multicast filter to receive all multicast address. And set/clear
IFF_ALLMULTI flag properly.
