net: fix network drivers ndo_start_xmit() return values (part 3)
Fix up wireless drivers that return an errno value to qdisc_restart(), causing
qdisc_restart() to print a warning an requeue/retransmit the skb.
- airo: transmission not implemented for chip, intention is to free and abort
- ipw2200: transmission not implemented for promiscous mode, intention is to
drop
- prism54: intention is to drop
- wl3501_cs: intention appears to be to drop
- zd1201: error counter indicates intention is to drop
All drivers compile tested.

Three major portions to this change:
1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.
2) Delete iw_stream_check_add_*(), they are unused.
3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.
4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3. Also, explicit references to IW_EV_LCP_LEN are
replaced with iwe_stream_lcp_len(info).
With a lot of help and bug fixes from Masakazu Mokuno.

Agreed, so sure, this is OK but I rather we turn the carrier on

Reviewing the semaphore usage I noticed these down_interruptible calls. Most
of these aren't returning anything, so a caller can't tell if the operation
completed or not. prism54_wpa_bss_ie_get() returns zero, but it's treated as
the function failing which doesn't seem correct.

It's been a useless no-op for long enough in 2.6 so I figured it's time to
remove it. The number of people that could object because they're
maintaining unified 2.4 and 2.6 drivers is probably rather small.

For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can
later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.
This one touches just the most simple case, next will handle the slightly more
"complex" cases.

Correct assignment of DOT1XENABLE in WE-19 codepaths.
RX_UNENCRYPTED_EAPOL = 1 really means setting DOT1XENABLE _off_, and
vice versa. The original WE-19 patch erroneously reversed that. This
patch fixes association with unencrypted and WEP networks when using
wpa_supplicant.
It also adds two missing break statements that, left out, could result
in incorrect card configuration.

perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f

And then go through and reinstate those cases where code is casting pointers
to non-pointers.
And then drop a few hunks which conflicted with outstanding work.

NET: prism54 - fix potential race in reset scheduling
There appears to be a race in reset scheduling logic - thread
responsible for reseting the interface should clear "reset
pending" flag before restarting the queue, otherwise timeout
handler might not schedule another reset even if it is needed.
This race is mostly theoretical as far as I can see but a race
nonetheless.
