This commit enables partial operation of dummynet with kernels
compiled with "options VIMAGE".
As it is now, there is still a single instance of the pipes,
and it is only usable from vnet0 (the main instance).
Trying to use a pipe from a different vimage does not crash
the system as it did before, but the traffic coming out from
the pipe goes to the wrong place, and i still need to
figure out where.
Support for per-vimage pipes is almost there (just a matter of
uncommenting the VNET_* definitions for dn_cfg, plus putting into
the structure the remaining static variables), however i need
first to figure out how init/uninit work, and also to understand
where packets are ending up on exit from a pipe.

Add initial jumbo frame support for BCM5714/BCM5715 and BCM5780.
Unlike other controllers which have more advanced jumbo support,
these controllers have one send ring, one standard receive producer
ring and one receive return ring. In order to receive jumbo frames
on the controllers, driver now will increase Rx buffer size to 9k.
Two Rx modes are supported on these controllers and I chose
standard Rx BDs over extended Rx BDs. The extended Rx BD mode
allows up to 4 segmentations for each Rx BDs such that kernel does
not have to allocate large buffer of contiguous memory for
receiving. The extended Rx BD mode is already used on controllers
that have separate jumbo receive ring. However, using extended Rx
BDs on BCM5714/BCM5715/BCM5780 reduces the number of Rx BDs to 256
entries which in turn may reduce the performance. Also UMA backed
page allocator for jumbo frame returns contiguous memory so using
extended Rx BD has no advantage on FreeBSD unless highly customized
local allocator implemented in driver is used.
To use jumbo buffers in standard receive ring, Rx buffer allocation
handler was changed to allocate MJUM9BYTES sized mbuf.
