#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.
Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.
Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.
- calculate each descriptor sizes and offsets in iee_attach() and store them
into softc, rather than re-calculating them everywhere via macros
- prepare macros to sync DMA shmem per each descriptor
- sync only necessary descriptors in iee_intr() and iee_start()
- make sure SCB_FOO macros take softc as an arg properly
- use bus_dmamap_load_mbuf(9) for RX mbufs
- put 2 byte alignments to RX mbufs
XXX: still slower than ie(4) in i82586 compat mode on HP9000 735/125.
from MD attachments to MI iee_attach().
Tested on HP9000 735/125. Compile test only on ews4800mips.
XXX: more strict bus_dmamap_sync(9) calls are required in various places.
big endian mode:
- add IEE_REV_A flag to indicate if chip support the 32 bit BE mode or not
- add IEE_SWAPA32() macro and use it on necessary 32 bit DMA pointers
- rename IEE_SWAP() macro for the SCP address pointer and statistics
counters which require word swap even on Rev B/C chips to IEE_SWAP32()
for clarification
- add comments about these BE mode quirks
Tested on HP9000 735/125 by me and also tested on 715/50 by skrll@

identify sockaddr_dl abuse that remains in the kernel, especially
the potential for overwriting memory past the end of a sockaddr_dl
with, e.g., memcpy(LLADDR(), ...).
as a side-effect. Don't bother handling IFF_PROMISC here, because
ether_ioctl() already calls (*if_init)() to handle flags changes.
When adding/deleting multicast addresses, only whack the address
filter if the interface is marked RUNNING.
Fixes kern/27678.
