fec39060e2 Fixing WEP bustage in hostap mode since 5.2-RELEASE.
- WEP TX fix:

  The original code called software crypto, ieee80211_crypto_encap(),
which never worked since IEEE80211_KEY_SWCRYPT was never flagged due to
ieee80211_crypto_newkey() assumes that wi always supports hardware based
crypto regardless of operational mode(by virtue of IEEE80211_C_WEP).
This fix works around that issue by adding wi_key_alloc() to force
the use of s/w crypto.  Also if anyone ever decides to cleanup ioctl
handling where key changes wouldn't cause a call to wi_init() every time,
we'll need wi_key_alloc() to DTRT.

  In addition to that, this fix also adds code to wi_write_wep() to force
existing keys to be switched between h/w and s/w crypto such that an
operation mode change(sta <-> hostap) will flag IEEE80211_KEY_SWCRYPT
properly.

- WEP RX fix:

  Clear IEEE80211_F_DROPUNENC even in hostap mode.  Quote from Sam:

	"This is really gross but I don't see an easy way around it.
	By doing it we lose the ability to independently drop unencode
	frames (and support mixed wep/!wep use).  We should really be
	setting the EXCLUDE_UNENCRYPTED flag written in wi_write_wep
	based on IEEE80211_F_DROPUNENC but with our clearing it we can't
	depend on it being set properly."

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

462fcd56a6 Older versions of the intersil firmware is a lot slower than newer
versions of the firmware.  It responds more slowly to commands, and we
bogusly failed them.  We assume that all versions of the intersil
firmware before 1.0 are 10 times slower and will give it 10x the time
to finish.

# for 5.2 we should always just assume 5s.

0e630ee24b o Lucent cards don't seem to like multiple buffers for tx. Use only
one tx buffer for these cards.  The old driver only used one.  We use
  1 for symbol, and 3 for prism cards.
o Don't do the maximum loops thing in the ISR.  In fact, revert to the
  old interrupt handler.  Lucent cards don't seem to work too well if
  you don't disable/enable interrupts from the card in the ISR.

Between these two changes, Lucent cards suck less.  They work in
autoselect mode only.  And seem to get 1Mbps or 2Mbps only.  Setting a
specific media speed doesn't work, and I've had a few issues even with
these patches.  They turn a former brick into a nearly useful card.

These patches work on the prism 2 and 2.5 PC Card cards that I have.
I've not tested this on PCI cards.  I suspect, but couldn't find
proof, that they were the reason that the ISR was changed so radically
from its FreeBSD roots in NetBSD.  We might need to have a variant ISR
if so.

572ab50c54 Move symbol reset detection code back into wi_reset. This is a more
reliable way to detect if the symbol cards have been reset or not.
This makes symbol cards work better.

e122b676e6 Replace the original host WEP implementation with the one in OpenBSD
(apparently by markus@, at least committed by him).  This has the
advantage of not using the bad IV's from Fluhrer/Mantin/Shamir as well
as bringing the drivers a little closer together.

Also use a few constants in place of magic numbers in one place.

1bd2b5b4cd Integrate the hostap stuff that Thomas Skibo <skibo@packbell.net>
wrote.  This code was for 4.5-release, so I've ported it to -current
and made a few minor tweaks.  The biggest non-style tweak was to not
make access point the default.

More changes will be needed to get this actually working, but I wanted
to get a relatively pure baseline.  This doesn't seem to break what
works now.

a19c104dd2 Four fixes from NetBSD:
1) Properly detect the Symbol based cards (The 3Com Airconnect and their
   ilk) and only reset them *ONCE* ever.  This appears to make them work,
   but more testing is needed.  The tests that would wedge up my machine
   completely now appear to work, but I have not real access points
   handy.
2) Report both the Station firmware and the Primary firmware on Prism
   based cards.  On Lucent based cards, only report the station firmware
   since that's all it supports.  On symbol cards, report the symbol
   specific firmware name as its station firmware.
3) Better Prism 2.5 and 3 family names.  We really need to go table
   driven for this.
4) Workaround for bugs in Intersil's firmware is only needed for at most
   0.8.2 and earlier, since 0.8.3 and later appear to work.
