the fxp driver. This is enabled only for the 82550/82551 chips
(PCI revision code 12 or 13). RX and TX checksum offload are
both supported. Transmit offload is limited to TCP and UDP only
right now: there seems to be a problem with IP header checksumming
on transmit in some cases.
This chip has hardware VLAN support as well. I hope to enable
support for this eventually.
- Make transmission of packets work again. This stopped working because
ether_ifattach() was forcing ifp->if_output to be ether_output() and
clobbering our attempt to override this vector with a pointer to
ng_fec_output(). Move the overriding of ifp->if_output to after
ether_ifattach().
- Abandon the use of the netgraph ng_ether_input_p hook for snagging
incoming frames, and instead override the ifp->if_input vector for
interfaces that have been aggregated into our bundle. (I would have
loved to have written things this way in the first place, but I
didn't want to have to be the one to implement the if_input hook
and change all the drivers.) This avoids collisions with the ng_ether
module, which uses the same hook. Each aggregated device now calls
ng_fec_input() directly, which then fakes up the rcvif pointer
before invoking ifp->if_input itself.
This module should actually work now.
that matches snd_max, then do not respond with an ack, just drop the
segment. This fixes a problem where a simultaneous close results in
an ack loop between two time-wait states.

If we are not going to rebuild (make rerelease -DRELEASENOUPDATE

${CHROOTDIR}/usr/src/sys/conf/newvers.sh, as the only effect that

"touch: not found" during rerelease? :-)

lgamma(3) manpage.

behavior less surprising when a read error occurs. The handler
does not attempt to distinguish errors from file truncation, but
anyone actively modifying a file while trying to compare it
shouldn't even expect something sane to happen.

changed since this code was written:
- The ng_ether_input_p hook only accepts two arguments now: the pointer
to the ether header structure is gone.
- It's no longer necessary to cons up a fake ether header before passing
incoming packets to BPF_MTAP().
ng_fec_input() has been modified to account for these two changes.
Running tcpdump on fec0 should work now.

- the mutex aac_io_lock protects the main codepaths which handle queues and
hardware registers. Only one acquire/release is done in the top-half and
the taskqueue. This mutex also applies to the userland command path and
CAM data path.
- Move the taskqueue to the new Giant-free version.
- Register the disk device with DISKFLAG_NOGIANT so the top-half processing
runs without Giant.
- Move the dynamic command allocator to the worker thread to avoid locking
issues with bus_dmamem_alloc().
This gives about 20% improvement in most of my benchmarks.
