controller.
AX88772B data sheet does not show detailed information about
checksum offloading related things. It seems the controller has
lots of options to support checksum offloading but I failed to
understand why this feature requires so much complex controller
configuration and status bits.
One of major difference between AX88772B and its predecessor is
AX88772B uses a new RX header format when RX checksum offloading is
enabled. It also requires the received length of a frame should be
multiple of 4. Controller will pad necessary bytes to make the
length of received frame to be multiple of 4. It is driver's
responsibility to offset this pad bytes.
Note, AX88772B could be configured to get partial checksum value in
in RX header. This mode uses different RX header format and
currently we don't use that fature.
This change makes axe(4) use driver specific MII attach handler to
override uether(9)'s default MII attach and announce flow-control
capability for AX88178/AX88772A/AX88772B to PHY drivers. It seems
original AX88772 also supports flow-control but I didn't enable it
due to lack of test/access to the controller. The flow-control
threshold parameter is loaded from EEPROM and there is no way to
override this value without reprogramming EEPROM. For AX88772B,
TX/RX IP/TCP/UDP checksum offloading is announced to network stack.
IPv6 and PPPoE checksum offloading is also supported by controller
but we have no way to take advantage of these features.
Driver already knows PHY address so make PHY driver know that
information and remove unnecessary PHY address check used in
miibus_readreg/miibus_writereg callbacks. Also announce AX88178,
AX88772A and AX88772B support VLAN over-sized frame.
While I'm here clean up headers and remove axe_start() in
axe_init() because the link wouldn't be available right after media
change.
common cases that can be handled in constant time. The insight being
that a page's parent in the vm object's tree is very often its
predecessor or successor in the vm object's ordered memq.

with older FreeBSD versions:
- Add -V option to 'geli init' to specify version number. If no -V is given
the most recent version is used.
- If -V is given don't allow to use features not supported by this version.
- Print version in 'geli list' output.
- Update manual page and add table describing which GELI version is
supported by which FreeBSD version, so one can use it when preparing GELI
device for older FreeBSD version.

interfaces. A host route has a NULL mask so check for that condition.
I have also been told by developers who customize the packet output
path with direct manipulation of the route entry (or the outgoing
interface to be specific). This patch checks for the route mask
explicitly to make sure custom code will not panic.

However, when deleting the route, simply changing the command keyword
from "add" to "delete" does not work. The failoure is observed in
both IPv4 and IPv6 route insertion. The patch makes the route command
behavior consistent between the "add" and the "delete" operation.

handler such that driver can announce interface capabilities and
can do its own MII attach. Currently all USB ethernet controllers
have no way to establish a link with pause capabilities. Lack of
checksum offloading support also was one of reason to bring this
change in.
This change adds a couple of wrappers to USB ethernet drivers
(uether_ifmedia_upd, uether_init and uether_start). All exported
functions in uether has prefix uether_ so I think it's more
consistent to have wrappers that follow the convention.
This change preserves ABI/KPI so it should be safe to merge this
change to stable/8.
While I'm here add missing __FBSDID and clean up headers.

non-legacy mountpoints. It is better to be able to rename such file systems and
let them be mounted in old places until next reboot than using live CD, etc. to
rename with remount.
This is implemented by adding -u option to 'zfs rename'. If file system's
mountpoint property is set to 'legacy' or 'none', there is no need to specify -u.
Update zfs(8) manual page to reflect this addition.

controller which is found on ULi M1563 South Bridge & M1689 Bridge.
These controllers look like a tulip clone.
M5263 controller does not support MII bitbang so use DC_ROM
register to access MII registers. Like other tulip variants, ULi
controller uses a setup frame to configure RX filter and uses new
setup frame format. It's not clear to me whether the controller
supports a hash based multicast filtering so this patch uses 14
perfect multicast filter to filter multicast frames. If number of
multicast addresses is greater than 14, controller is put into a
mode that receives all multicast frames.
Due to lack of access to M5261, this change was not tested with
M5261 but it probably works. Many thanks to Marco who provided
remote access to M5263.

link such that calling dc_setcfg() right after media change would
be meaningless unless controller in question is not Davicom DM9102.
Ideally dc_setcfg() should be called when speed/duplex is resolved
otherwise it would reprogram controller with wrong speed/duplex
information. Because MII status change callback already calls
dc_setcfg() I think calling dc_setcfg() in dc_init_locked() is
wrong. For instance, it would take some time to establish a link
after mii_mediachg(), so blindly calling dc_setcfg() right after
mii_mediachg() will always yield wrong media configuration.
Extend dc_ifmedia_upd() to handle media change and still allow
21143 and Davidcom controllers program speed/duplex regardless of
current resolved speed/duplex of link. In theory 21143 may not need
to call dc_setcfg() right after media change, but leave it as it is
because there are too many variants to test that change. Probably
dc(4) shall need a PHY reset in dc_ifmedia_upd() but it's hard to
verify correctness of the change.
This change reliably makes ULi M5263 establish a link.
While I'm here correctly report media change result. Previously it
always reported a success.
I have some packages that install to / (for whatever reason). Right now we
print entries of the form //path/to/file when listing files (pkg_info -L,
pkg_info -g etc.) This change avoids printing the redundant / .
