In general, vm_map_simplify_entry should be performed INSIDE
the loop that traverses the map, not outside. (Changed:
vm_map_inherit, vm_map_pageable.)
vm_fault_unwire doesn't acquire the map lock (or block holding
it). Thus, vm_map_set/clear_recursive shouldn't be called.
(Changed: vm_map_user_pageable, vm_map_pageable.)
- add support for devices that do vlan tag insertion/deletion in firmware
- add multicast support
- add vlan_unconfig() to complement vlan_config()
- update ifconfig(8) to configure vlan interfaces (vlan tag and
parent device)
Also fix a small bug in ifconfig; sometimes sa_family is overwritten
by ioctls.

WARNING: this is not a real fix. Something really funny must be
happening in the page table entries for the physical memory
0x0-0xa0000, which is mapped to the beginning of the kernel region.
The old VN device broke in -4.x when the definition of B_PAGING
changed. This patch fixes this plus implements additional capabilities.
The new VN device can be backed by a file ( as per normal ), or it can
be directly backed by swap.
Due to dependencies in VM include files (on opt_xxx options) the new
vn device cannot be a module yet. This will be fixed in a later commit.

chip int. and ext. clock synchronisation). Fixed workaround for
transmit threshold underrun. Added volatile keyword to CSR_READ_* and
CSR_WRITE_* macroses. Added DELAYs to eliminate randomness caused
by processor speed. Fixed all TXCON and RXCON registers to be accessed
only when chip is idle, as manual told. Changed epic_init_phy to
drop link by isolating and going loopback, should should force link
partner to restart autonegotiation.

1. The size of vm_object::memq is vm_object::resident_page_count,
not vm_object::size.
2. The "size > 4" test sometimes results in the traversal of a ~1000 page
memq in order to locate ~10 pages.
write performance when tagged queueing is enabled.
Although the PR was submitted for the 4 gig version of this drive, the
assumption is that the 2 gig version has the same problem. Therefore
tagged queueing is disabled for both.
Also, update the comment for the Western Digital Enterprise drives to note
that the best performance for those drives is achieved when tagged queueing
is disabled and write caching is enabled.

a wierd double-queue arrangement.. It always empties the if_snd queue
then puts the transmit packets into a different queue that is limited
by the number of TX descriptors and does it's own discards...
This should stop the boot-time XXX warning anyway.
MMalloc: save the time at which the request was granted, remove more
crud.
FFree: add a circular buffer of the last 64 Free requests if
DEBUG_MEMFREE is set.
