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
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
would be overwritten, so allocate memory for a full packet via malloc()
instead. Use correct buffer maxlen (must be 2 complemet). Bug reported
and helped to find by Roar Thronæs.
