mmap() on NTFS files was hosed, returning pages offset from the
start of the disk rather than the start of the file. (ie, "cp" of
a 1-block file would get you a copy of the boot sector, not the
data in the file.) The solution isn't ideal, but gives a functioning
filesystem.
Cached vnode lookup was also broken, resulting in vnode haemorrhage.
A lookup on the same file twice would give you two vnodes, and the
resulting cached pages.
Just recently, mmap() was broken due to a lack of a call to
vnode_create_vobject() in ntfs_open().

null-modem tty device emulate the speed settings faithfully.
The speed is emulated independently for the two directions, using
the slower of the local sides ispeed and the remote sides ospeed.
The emulated speed takes settings of bits/char, parity and stopbit
into account.

the interface when going to toggle VLAN support for
internal reasons. If the IFCAP_VLAN_HWTAGGING bit is
cleared, we should rely on the (re)init routine to turn
VLAN support off and never touch the relevant hardware bits.
This applies to other capability bits, too. The user
obviously has a reason for clearing a capability bit,
e.g., if his particular NIC is buggy and hangs if a
certain hardware capability is turned on even for a
fraction of a second.
The flag adapter->em_insert_vlan_header still is set or
reset irrespective of the IFCAP_VLAN_HWTAGGING setting,
as before, in order to handle the case when a user sets
promiscuous mode on an interface first and later turns
its IFCAP_VLAN_HWTAGGING bit on.
This change might look orthogonal to rev#1.85, but in fact
it is not. It introduces bugfixes that hopefully will make
implementing the general scheme mentioned in the commit
message of rev#1.85 easier.
configuration: it appears to work properly in the non-promiscuous case, but
we've not yet implemented a more general solution that maintains full
functionality with promiscuous mode enabled. While my hope is that we can
get one implemented soon, this will improve functionality substantially in
the mean time.

AX88190 ones, but that one only minorly):
o don't set flags in the match routine. They appear to be cleared
when probe/attach is called. Before this change, they were
always treated as a simple ne2000, which would fail to get the
right NIC address.
o Lookup device again in the probe routine and probe based on the
cards that you see.
o Detect and report the DL10022 seprately from the DL10019 cards.
While I'm here:
o remove a bad printf
o change another bad printf to device_printf.
o minor style(9) formatting tweaks.

This makes all of my DL100xx cards at least probe the ethernet address

AX88xxx based cards, so those haven't been tested, but they were
busted before the change so they can't be any worse now...

ethernet address was moved into ether_attach, and so we were printing
orphaned information about the card. Now the probe message is
prefixed by edX:. Prepare for it to move under bootverbose, but don't
move it there yet (the || 1 trick).
