- 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."

o Axe poll in trap.
o Axe IFF_POLLING flag from if_flags.
o Rework revision 1.21 (Giant removal), in such a way that
poll_mtx is not dropped during call to polling handler.
This fixes problem with idle polling.
o Make registration and deregistration from polling in a
functional way, insted of next tick/interrupt.
o Obsolete kern.polling.enable. Polling is turned on/off
with ifconfig.
Detailed kern_poll.c changes:
- Remove polling handler flags, introduced in 1.21. The are not
needed now.
- Forget and do not check if_flags, if_capenable and if_drv_flags.
- Call all registered polling handlers unconditionally.
- Do not drop poll_mtx, when entering polling handlers.
- In ether_poll() NET_LOCK_GIANT prior to locking poll_mtx.
- In netisr_poll() axe the block, where polling code asks drivers
to unregister.
- In netisr_poll() and ether_poll() do polling always, if any
handlers are present.
- In ether_poll_[de]register() remove a lot of error hiding code. Assert
that arguments are correct, instead.
- In ether_poll_[de]register() use standard return values in case of
error or success.
- Introduce poll_switch() that is a sysctl handler for kern.polling.enable.
poll_switch() goes through interface list and enabled/disables polling.
A message that kern.polling.enable is deprecated is printed.
Detailed driver changes:
- On attach driver announces IFCAP_POLLING in if_capabilities, but
not in if_capenable.
- On detach driver calls ether_poll_deregister() if polling is enabled.
- In polling handler driver obtains its lock and checks IFF_DRV_RUNNING
flag. If there is no, then unlocks and returns.
- In ioctl handler driver checks for IFCAP_POLLING flag requested to
be set or cleared. Driver first calls ether_poll_[de]register(), then
obtains driver lock and [dis/en]ables interrupts.
- In interrupt handler driver checks IFCAP_POLLING flag in if_capenable.
If present, then returns.This is important to protect from spurious
interrupts.

the softc.
- Use callout_init_mtx() and rather than timeout/untimeout in both rl(4)
and re(4).
- Fix locking for ifmedia by locking the driver in the ifmedia handlers
rather than in the miibus functions. (re(4) didn't lock the mii stuff
at all!)
- Fix some locking in re_ioctl().
Note: the two drivers share the same softc declared in if_rlreg.h, so they
had to be change simultaneously.

routing, etc. in a static pci_assign_interrupt() function.
- Add a sledgehammer that allows the user to override the interrupt
assignment of any PCI device via a tunable (e.g. "hw.pci0.7.INTB=5" would
force any functions on the pci device in slot 7 of bus 0 that use B# to
use IRQ 5). This should be used with great caution! Generally, if the
interrupt routing in use provides specific tunables (such as hard-wiring
the IRQ for a given $PIR or ACPI PCI link device), then those should be
used instead. One instance where this tunable might be useful is if a
box has an MPTable with duplicate entries for the same PCI device with
different IRQs.

make function reenterable. In the runtime the race is masked by serializing
of em_process_receive_interrupts() either by interrupt thread, or by
polling. The race can be triggered when polling is switched on or off.

It should probably be rewritten to implement a simple bus to which
the sub drivers attach using some kind of hint.
Until then, provide a couple of crutch functions with big warning
signs so it can survive the recent changes to struct resource.
and do some preparations for handling 12x22 fonts (currently lots of code
implies and/or hardcodes a font width of 8 pixels). This will be required
on sparc64 which uses a default font size of 12x22 in order to add font
loading and saving support as well as to use a syscons(4)-supplied mouse
pointer image.
This API breakage is committed now so it can be MFC'ed in time for 6.0
and later on upcoming framebuffer drivers destined for use on sparc64
and which are expected to rely on using font loading internally and on
a syscons(4)-supplied mouse pointer image can be easily MFC'ed to
RELENG_6 rather than requiring a backport.

control register and AGP bridge seems to be inconsistent with some BIOS.
Instead of relying on BIOS settings, we just take the initial aperture size
and encode them for both miscellaneous control register and AGP bridge.
Some idea was borrowed from agp_nvidia.c.
- Add preliminary ULi M1689 chipset support. The idea was taken from Linux

Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash. Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.
In fact, this change do nothing for this driver. It is protected from
this by cp_destroy variable. This variable also protects driver from initiation
of any activity from network stack with disabled intr handler with this change

number of cards have been discovered to be matching on the strings of
the cis rather than manufacturer/product id for cards we already had a
prod id for. This is a result of getting the list from the NetBSD
driver which also includes the OID for the cards where such a
distinction mattered (since it was tested against the MAC address we
got from the card). Since we do not try to match OIDs, we do not need
the extra entries and they just waste space.
I'm guessing that some of the dlink entires (DE-660, DE-660+) and many
of the corega cards may fall into this boat and can safely be removed.
