This solves the problem, where in a constellation with two (or more)
drives, an attempt is made to access a device name for that device

always created to /dev/fd0, even if the request was for fd1*.
aac.c:
Re-arrange the interrupt handler to optimize the common case of
the adapter interrupting us because one or more commands are complete,

This abstracts out all the differences I could see between the netbsd

in NIC memory, so they must be referenced using 32-bit accesses.
Smaller accesses have been observed to fail under some conditions.
This caused the rings to be set up wrong, leading to writes by the
card outside of the intended bounds of the rings. This problem was

were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a "copy" operation. This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain. This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.
These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block. This
introduces an incompatibility with openbsd which we may want to revisit.
Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them. We may want to support this;
for now we watch for it with an assert.
Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.
