Because the Fritz!Card PCMCIA stuff is also affected, this includes the fix
from PR kern/10278 submitted by Udo Schweigert (udo.schweigert@mchp.siemens.de).

block (VM_WAIT) holding the map lock. This is bad. For example, a subsequent
kmem_malloc by an interrupt handler on the same map may find the lock held
and panic in the lockmgr.
levels (-O3 and above) won't remove essential code. Many thanks
to Dmitrij Tejblum <dima@tejblum.dnttm.rssi.ru> for pointing out
that it was the optimizer's removal of this code that caused make
world with -O3 to break. With this change, make buildworld now
completes.
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.

switching video modes. People typically see the panic when the screen
saver has been running and is being stopped.
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.
