- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)
use from checking the proc's uid to suser(9), and account for the use of
privileges. Noted by David Holland in PR kern/31126.
Also change this to use the proc argument instead of curproc.
ether_ioctl() will call (*if_init)() when flags change. Instead, do
what other drivers do and stop the interface in this case before
re-initializing.
- qtioctl(): Now that qtinit() does the right thing, remove the check
for IFF_PROMISC change.
When adding/deleting multicast addresses, only whack the address
filter if the interface is marked RUNNING.
Fixes kern/27678.
allocate a static buffer, which is added at the end of short packets
to pad the buffer to ETHER_MIN_LEN - ETHER_CRC_LEN.
While I'm there fix 2 bugs:
in qeinit(), unload the right dmamap if bus_dmamap_load fails
in qestart, don't dmamap_load the mbuf if its len is 0.
Tested on simh-vax.
XXX should it be ETHER_MIN_LEN - ETHER_CRC_LEN ?
XXX2 we assume there are enouth space in the mbuf for the padding bytes.
But other places in the code assumes this already.
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
