Create a wrapper for newbus to take giant and for busses to take it too.
bus_topo_lock() should be called before interacting with newbus routines
and unlocked with bus_topo_unlock(). If you need the topology lock for
some reason, bus_topo_mtx() will provide that.

We can now set promisc and allmulti modes.
Filtering of given multicast addresses is not supported.
Changing the mode is done by sending a command described in:
"USB CDC Subclass Specification for Ethernet Devices v1.2, section 6.2.4".
This means that at least in theory this feature should work with all
modems that are using this driver.
This fixes Huawei E3372h-320 running new firmware in "HiLink" mode.
Previously it would reset a few seconds after its mode was changed
with "usb_modeswitch".
Setting RX filter to default value at the end of attach function
fixed that.

This makes it more usable in that dhclient will autolaunch from devd
now when cdce devices are plugged in.. It also sets the baudrate, but
this isn't exported via tools, and CDCE doesn't have a good way to
specify the media type, so there isn't a good way to tell userland
what the speed is currently...

When detaching the if_ure(4) driver, the TX active USB transfer array may
point to freed USB transfers. Given that the number of USB transfers is
very low, simply start all transfers every time there is a packet to
keep safe from use-after-free.

This update adds support for:
HW VLAN tagging
HW checksum offload for IPv4 and IPv6
tx and rx aggreegation (for full gige speeds)
multiple transactions
In my testing, I am able to get 900-950Mbps depending upon
TCP or UDP, which is a significant improvement over the previous
91Mbps (~8kint/sec*1500bytes/packet*1packet/int).

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked). Use it in
preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Some places in network code may need to verify that an ethernet address
is not the 'zero' address. Provide a standard macro ETHER_IS_ZERO for
this purpose, similar to the ETHER_IS_BROADCAST macro already available.
This patch also removes previous ETHER_IS_ZERO definitions in several
USB ethernet drivers, in favor of this centrally-located macro.
