sctp: fix compile error due to sysctl mismerge
I messed up the merge in
d7fc02c7bae7b1cf69269992cf880a43a350cdaa, where
the conflict in question wasn't just about CTL_UNNUMBERED being removed,
but the 'strategy' field is too (sysctl handling is now done through the
/proc interface, with no duplicate protocols for reading the data).

This patch fixes a bug in ath9k's tx status check, which
caused mac80211 to consider regularly transmitted unicast frames
as un-acked.
When checking the ts_status field for errors, it needs to be masked
with ATH9K_TXERR_FILT, because this field also contains other fields
like ATH9K_TX_ACKED.
Without this patch, AP mode is pretty much unusable, as hostapd
checks the ACK status for the frames that it injects.

On a 32-bit machine, BIT() macro does not give the required

BIT() is suppossed to get the bit value more than 31 (42 (id of ERP_INFO_IE),

mwl8k: increase firmware loading timeouts
The time between loading the helper image and starting to upload the
main firmware image should be at least 5 ms or so. We were doing an
msleep(1) before, and 1 ms appears to not be enough in almost all
cases, but building with HZ=100 has always masked this so far. Bumping
the msleep argument to 5 fixes firmware loading e.g. when HZ=1000.
Some firmware images need more than 200ms to initialize. Bump the
ready code timeout to 500ms to accommodate for this.

mwl8k: allow more time for transmit rings to drain
Before issuing any firmware commands, we wait for the transmit rings
to drain, to prevent control versus data path synchronization issues.
In some cases, this can end up taking longer than the current hardcoded
limit of 5 seconds, for example if the transmit rings are filled with
packets for a host that has dropped off the air and we end up
retransmitting every pending packet at the lowest rate a couple of
times.
This patch changes mwl8k_tx_wait_empty() to only bail out on timeout
expiry if there was no change in the number of packets pending in the
transmit rings during the waiting period. If at least one transmit
ring entry was reclaimed while we were waiting, we are apparently still
making progress, and we'll allow waiting for another timeout period.

mwl8k: fix addr4 zeroing and payload overwrite on DMA header creation
When inserting a DMA header into a packet for transmission,
mwl8k_add_dma_header() would blindly zero the addr4 field, which
is not a good idea if the packet being transmitted is actually a
4-address packet.
Also, if the transmitted packet was a 4-address with QoS packet,
the memmove() to do the needed header reshuffling would inadvertently
overwrite the first two bytes of the packet payload with the QoS field.

mwl8k: prevent corruption of QoS field on receive
Packets exchanged between the mwl8k driver and the firmware always
have a 4-address header without QoS field. For QoS packets, the QoS
field is passed to/from the firmware via the tx/rx descriptors.
We were handling this correctly on transmit, but not on receive -- if
a QoS packet was received, we would leave garbage in the QoS field in
the packet passed up to the stack, which is Bad(tm).
Also, if the packet received on the air was a 4-address without QoS
packet, we would forget to skb_pull the 2-byte DMA length prefix off.
This patch adds an argument to the ->rxd_process() receive descriptor
operation to retrieve the QoS field from the receive descriptor, and
extends mwl8k_remove_dma_header() to insert this field back into the
packet if the packet received is a QoS packet. It also fixes
mwl8k_remove_dma_header() to strip off the length prefix in all cases.

mwl8k: fix UPDATE_STADB command struct legacy_rates array length
There exist 12 802.11b/g rates, but mwl8k supports two additional
(non-standard) rates, and includes those rates in rate bitmasks and
in its internal rate table that hardware rate indices index.
Commit "mwl8k: report rate and other information for received frames"
added one of the nonstandard rates to the mwl8k_rates table to make
the OFDM rates in the table line up with the rate indices that are
reported in the receive descriptor (so that we can just simply copy
the receive descriptor rate index into ieee80211_rx_status::rate_idx)
and bumped MWL8K_IEEE_LEGACY_DATA_RATES from 12 to 13, but this
screwed up the UPDATE_STADB command struct layout, as it also uses
that define, for its legacy_rates array.
To avoid having to convert rate indices and legacy rate bitmaps (e.g.
ieee80211_bss_conf::basic_rates) between the 12-rate mac80211 format
and the 14-rate mwl8k format, we'll report all 14 rates in our wiphy's
band, but filter out the nonstandard ones e.g. in the case of the
UPDATE_STADB command which only accepts 12 rates.
In the commands that accept 14 rates (SET_AID, SET_RATE), replace the
use of the MWL8K_RATE_INDEX_MAX_ARRAY define in the command struct by
the constant 14, to make it clearer that these commands accept 14 rates.

there's no need to queue a work routine to resume it. Setting the
deferred_resume flag will suffice. (There's also a minor improvement
to the function's code layout: An unnecessary "else" is removed.)
Also, the patch clarifies the usage of the deferred_resume flag. It
is meaningful only while a suspend is in progress, so it should be
