same functionality. Sharing code should help cache issues.
Remove in_cksum_partial, since its not being used, and we now have
a way to compute partial checksums on mbuf chains.
for transmit to the adapter, not when we receive a transmit interrupt
indicating that they were sent. This fix now allows tcpdump to produce
sane results by recording the timestamp at the point where the mbuf was
actually transmitted.
can use all of the s/g entries available on smaller cards. This is
necessary if we want to be able to handle a non-page-aligned 64k transfer
on 2.x and 3.x firmware.
Fix a missing splx() that may have left us at splbio() for longer than
desired.
Reduce shadowing of controller-supplied parameters a little.
better recovery for multiple packet losses in a single window.
The algorithm can be toggled via the sysctl net.inet.tcp.newreno,
which defaults to "on".

code instead of using 32-bit code and having to just "know" that it's
really 16-bit instructions when things run. This also allows the code
to use fewer macros and more actual assembly statements, which eases
maintenance. Unfortunately, due to as(1) brokenness, we still use m4
macros for all 16-bit addresses, and all short jumps (i.e., 8-bit
relative addresses in the jump instruction) must be wrapped in .code32
directives to avoid useless bloat by as(1). This also fixes a few
problems that were preventing boot0 from compiling with the latest
and greatest version of as(1).
the case where we receive a packet that wraps from the end of the
RX buffer back to the start. This fixes an unaligned access trap on
the alpha with NFS.
<sys/bio.h>.
<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.
Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.
Still a few bogus uses of struct buf to track down.

- Properly handle 32 bit sequence numbers when they wrap around
- Don't drop GRE packets with stale ACK numbers, just ignore the ACK
- Close race between node being shutdown and timer going off
Also add support for lots of statistics, and control message ASCIIfication
spl() protection in the case of a copyout error.
Add missing spl calls around the intial activation call that is
done when when the kevent is added.
Add two KASSERT macros to help catch errors in the future.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk. This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.
which seems to correspond better with what a busy plex needs. This
may also help us avoid race conditions when expanding the table which
may have been contributing to the random corruption, panics and hangs
we've been seeing in RAID-5 plexes, particularly with ata drives.

Get counting volume I/Os right.
launch_requests: Be macho, throw away the safety net and walk the
tightrope with no splbio().
Add some comments explaining the smoke and mirrors.
Remove some redundant braces.
sdio: Set the state of an accessed but down subdisk correctly. This
appears to duplicate an earlier commit that I hadn't seen.
Get counting volume I/Os right.
Count buffer sizes correctly for architectures where ints are not 32 bits.
complete_rqe: Move decrementing active count until after call to
complete_raid5_write, thus possibly avoiding a race condition.

Rename user bp to ubp to avoid confusion.
Tidy up comments.
