do not do a curproc test for interrupt context, because it is plainly wrong.

commit the correct version of this, which matches recent additions.

Don't use M_DUP_PKTHDR() on static mbufs. M_DUP_PKTHDR() copies the mtag
chain and so a later MFREE() is needed to free the chain again.
In this special case we get away by initializing a minimal mbuf header
instead of the M_DUP_PKTHDR() because bpf_mtap() does not access the pkthdr.
This fixes kettenis@ mtag memory leak on armish.

don't schedule a USB task in {ural,rum}_newstate() if we're called from
a process context. this avoids potential races in {ural,rum}_stop().

do not have each net80211 driver define its own rates structures. if they use
the standard rates, use some defined by net80211 itself. kernel shrinks a bit
ok jsg mglocker

restore the workaround for rate==0 bug.
i removed it in my last commit because i thought it was gone.
looks like it's not the case.

first round of commits for proper 11b/g protection support:
- use the newly introduced ieee80211_get_rts() and
ieee80211_get_cts_to_self() functions.
- use CTS-to-self instead of RTS/CTS to protect

- use the newly introduced ieee80211_get_rts() and
ieee80211_get_cts_to_self() functions.
- use CTS-to-self instead of RTS/CTS to protect OFDM frames in
a mixed 11b/g BSS.
- make sure multicast frames are sent using CCK modulation.

remove support for 5GHz radios in ral(4) RT2560 and ural(4).
i'm not aware of any such adapters on the market and 11a code
is known to be broken.

some cleanup while i'm here.

make sure ni->ni_txrate is always initialized to a meaningful value by
redefining ic->ic_newassoc.
this should prevent "bogus xmit rate" panics when operating in HostAP
mode.

Support later versions of the ASUS WL-167g which have switched
from ural to rum.

From Jason Crawford <jasonrcrawford@gmail.com>

don't use IF_PREPEND() on altq's.
use IFQ_POLL()/IFQ_DEQUEUE() logic instead as described in altq(4).

s/IEEE80211_MTU_MAX/IEEE80211_MAX_LEN/ in my previous commit.

- fall back to 1Mbps if tx rate is returned as zero. avoids divide by zero. should never happen, but sometimes it does on my amd64.

the maximum MTU allowed for IEEE802.11 is 2290 which is greater than
MCLBYTES (usually 2048).
allocate tx xfer buffers of IEEE80211_MTU_MAX instead of MCLBYTES.
rx buffers are still limited to MCLBYT

in rum_rxeof(), don't check xfer length against IEEE80211_MIN_LEN since
the CRC is not included in the xfer.
check against sizeof(struct ieee80211_frame_min) instead.

set of unrelated cosmetic tweaks.
