32371d2025 MFp4: Fix automatic snapshot mount when unprivileged user does lookup
on a snapshot directory:
- Remove PRIV_VFS_MOUNT check - regular users can mount snapshots
  via lookups on snapshot directory.
- Reset mount credential to kcred, so user won't be able to unmount
  the snapshot.
- Reset owner uid.
- Unlock vnode in case of a failure.

f2c9a576db MFp4: We check for PRIV_VFS_MOUNT already in mount(2) syscall and we don't
want to do the check when snapshot is automatically mounted by an
      unprivileged user doing lookup on a snapshot directory.

eed497bbe5 Don't reinitialize the hardware if only PROMISC flag was changed.
Previously whenever PROMISC mode turned on/off link renegotiation
occurs and it could resulted in network unavailability for serveral
seconds.(Depending on switch STP settings it could last several tens
seconds.)

9eab54debf When we run into the syncache entry limits syncache_add() tries
to free the oldest entry in the current bucket row.  The global
entry limit may be smaller than the bucket rows and their limit
combined however.  Thus only try to free a syncache entry if we
found one in this bucket row.

90dea4f9a7 When trying to allocate a PnP BIOS memory resource, the code loops trying
to move up the start address until the allocation succeeds.  If the
alignment of the resource was 0, then the code would keep trying the same
request in an infinite loop and hang.  Force the request to always move
start up by at least 1 byte each time through the loop.

1c04bd82a5 Improve the if_vr driver ever so slightly.
The 6105M and 6102 does not have the DWORD alignment problem, so
don't m_defrag() every packet in the transmit path for those.

More stringent usage of tx-descriptor ring and its flags.

Tested on 6102 and 6105M, other chips may also be able to run
without the m_defrag() but I have neither hardware nor docs to
find out.

18242d3b09 Rename the trunk(4) driver to lagg(4) as it is too similar to vlan trunking.
The name trunk is misused as the networking term trunk means carrying multiple
VLANs over a single connection. The IEEE standard for link aggregation (802.3
section 3) does not talk about 'trunk' at all while it is used throughout IEEE
802.1Q in describing vlans.

The lagg(4) driver provides link aggregation, failover and fault tolerance.

478d3f0901 - Add more comments to sctps_stats struture in sctp_uio.h
- Fix bug that prevented EEOR mode from working
  and simplified the can_we_split code in the process.
- Reduce lock contention for the tcb_send_lock. I did
  this especially for EEOR mode, still need to look at
  why I need a lock when removing from the tailq and the
  ->next is NOT null. A lock fixes it but it implies a
  bug yet exists.
- Activated Andre's proposed changes to better use the mbuf
  infrastructure.
- Fixed places that were not using the aloc macro's to take
  advantage of the per assoc cache.
- Adds ifdef fix so any logging will enable stat_logging to
  get the right data structures in place (suggested by Max Laier).

2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
use to synchornize and protect all data objects that are used for that
SIM.  Drivers that are not yet MPSAFE register Giant and operate as
usual.  RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.

The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.
