frames in promiscuous mode. The RTL8169 datasheet was not clear
how it handles multicast frames in promiscuous mode.

a pointer to struct bus_space. The structure contains function
pointers that do the actual bus space access.
The reason for this change is that previously all bus space
accesses were little endian (i.e. had an explicit byte-swap
for multi-byte accesses), because all busses on Macs are little
endian.
The upcoming support for Book E, and in particular the E500
core, requires support for big-endian busses because all
embedded peripherals are in the native byte-order.
With this change, there's no distinction between I/O port
space and memory mapped I/O. PowerPC doesn't have I/O port
space. Busses assign tags based on the byte-order only.
For that purpose, two global structures exist (bs_be_tag and
bs_le_tag), of which the address can be taken to get a valid
tag.

is actually a circular log. Deal with it rolling around. Fortunately,
the log area is big and I haven't seen any roll over yet. Update and
get rid of the obsolete comment.
When system ticks are positive, for entries in the cache
bucket, syncache_timer() ran on every tick (doing nothing
useful) instead of the supposed 3, 6, 12, and 24 seconds
later (when it's time to retransmit SYN,ACK).
When ticks are negative, syncache_timer() was scheduled
for the too far future (up to ~25 days on systems with
HZ=1000), no SYN,ACK retransmits were attempted at all,
and syncache entries added in that period that correspond
to non-established connections stay there forever.
Only HEAD and RELENG_7 are affected.

that as new IPv6 TCP connections were created, kernel memory would
gradually leak.
