Rewrite node to support multiple hooks, alike to ng_l2tp, to use one pair
of pptpgre and ksocket nodes for all calls between two peers. This patch
modifies node's API by adding new "session_%04x" hook names support, while
keeping backward compatibility.
Fix a buffer overflow in the processing of various SCSI commands. This
likely fixes a great number of weird problems that have been reported
with this driver.
Merge from Adaptec a 64 bit fix and a workaround for luns != 0
returning CAM_SEL_TIMEOUT on SAS controllers, which prevented
passthrough devices from being created.
Restore creation of passthrough devices with newer controller firmware by
putting the correct size in the fib header. Presumably the older firmware
silently ignored a bad size field.
(This change tested with a 3805 controller. Passthrough devices were
created when running firmware build 12814, but not 15323 or later. With
this change they're created for both old and new firmware versions.)

Diff reduction to Adaptec driver build 15317 (refactoring and code shuffling):
- Resource allocation in aac_alloc (moved from from aac_init)
- Interrupt setup in aac_setup_intr (from aac_attach)
- Container probing in aac_get_container_info (from aac_startup and
aac_handle_aif)
- Firmware status check moved to aac_check_firmware from aac_init

Modify the signal handler frame setup code to clear the DF {e,r}flags
bit on the amd64/i386 for the signal handlers.
Improve apply callback error reporting:
Before this patch callback returned result of the last finished call chain.
Now it returns last nonzero result from all call chain results in this request.
As soon as this improvement gives reliable error reporting, it is now possible
to remove dirty workaround in ng_socket, made to return ENOBUFS error statuses
of request-response operations. That workaround was responsible for returning
ENOBUFS errors to completely unrelated requests working at the same time
on socket.
Add session ID hashing to speedup incoming packets dispatch in case
of many connections working via the same tunnel. For example, in case
of full "client <-> LAC <-> LNS" setup.
Fix link state handling in bfe(4).
o conversion to callout(9) API.
o add a missing driver lock in bfe_ifmedia_sts().
o use our callout to drive watchdog timer.
o restart Tx routine if pending queued packets are present in
watchdog handler.
o unarm watchdog timer only if there are no queued packets.
o don't blindly reset phy and let phy driver handle link change
request in bfe_init_locked().
o return the status of mii_mediachg() to caller in
bfe_ifmedia_upd(). Previously it always returned 0 to caller.
o add check for IFF_DRV_RUNNING flag as well as IFF_DRV_OACTIVE
in bfe_start_locked().
o implement miibus_statchg method that keeps track of current
link state changes as well as negotiated speed/duplex/
flow-control configuration.
Reprogram MAC to appropriate duplex state. Flow-control
configuration was also implemented but commented out at the
moment. The flow-control configuration will be enabled again
after we have general flow-control framework in mii layer.
Plug memory leak in jumbo buffer allocation failure path.
Patch in the PR was modified to check active jumbo buffers in use
and other possible jumbo buffer leak.
Jumbo buffer usage in lge(4) still wouldn't be reliable due to lack
of driver lock in local jumbo buffer allocator. Either introduce
a new lock to protect jumbo buffer or switch to UMA backed page
allocator for jumbo frame is required.
I've removed informational device_printf in lge_free_jumbo_mem as
lge_dev member variable in softc does not exist on RELENG_6.
if_printf can't be used as sc->lge_ifp could be NULL.

To overcome hardware checksum offload bug msk(4) used to compute
TCP/UDP checksum in driver for short frames. For frames that requires
hardware VLAN tag insertion, the checksum offload trick does not
work due to changes of checksum offset in mbuf after the VLAN tag.
Disable hardware checksum offload for VLAN interface to fix the bug.
Workaround GMAC hardware hang of Yukon II on the receipt of pause
frames. This bug seems to happen on certain hardware model/revision
(e.g. 88E8053) but it's not identified which hardwares are affected.
Revision 1.4 of if_mskreg.h was not enough to workaround the bug.
To workaround it, inrease GMAC FIFO threshold by one FIFO word to
flush received pause frames.
Some PIIX4 chipsets need to be told to generate Stop Breaks by
setting
the appropriate bit in the DEVACTB register.
This change allows the C2 state on those systems to work as expected.
