Gábor Stefanik 1e711bee56 b43: LP-PHY: Implement channel switching for rev0/1/B2062 radio
-Move pdiv from lpphy_2062_init to struct b43_phy_lp.
-Add channel table for the B2062 radio.
-Add code for tuning the B2062 radio to channel.
-Add error handling to op_switch_channel, and use it for both radios.

Rev0/1/B2062 will now hopefully show some signs of life, though
it won't work at full performance, as calibration is still missing.

Daniel C Halperin 396887a2b2 iwlwifi: fix erroneous use of iwl_rx_packet.len as a length
The field called 'len' in struct iwl_rx_packet is in fact not just a length
field but also includes some flags from the flow handler.  In several places
throughout the driver, this causes incorrect values to be interpreted as
lengths when the field is improperly masked.

In most situations the improper use is for debugging output, and simply results
in an erroneous message, such as:

[551933.070224] ieee80211 phy0: I iwl_rx_statistics Statistics notification received (480 vs -1367342620).

which should read '(480 vs 484)'.

In at least one case this could case bad things to happen:

void iwl_rx_pm_debug_statistics_notif(struct iwl_priv *priv,
                                      struct iwl_rx_mem_buffer *rxb)
{
        struct iwl_rx_packet *pkt = (struct iwl_rx_packet *)rxb->skb->data;
        IWL_DEBUG_RADIO(priv, "Dumping %d bytes of unhandled "
                        "notification for %s:\n",
                        le32_to_cpu(pkt->len), get_cmd_string(pkt->hdr.cmd));
        iwl_print_hex_dump(priv, IWL_DL_RADIO, pkt->u.raw, le32_to_cpu(pkt->len)
);
}
EXPORT_SYMBOL(iwl_rx_pm_debug_statistics_notif);

Given the rampant misuse of this field without proper masking throughout the
driver (every use but one), this patch renames the field from 'len' to
'len_n_flags' to reduce confusion.  It also adds the proper masking when
this field is used as a length value.

Daniel C Halperin b261793da5 iwlwifi: use station HT capabilities and BSS operating mode for Green-field
Green-field mode should be configured in the HT station table.  This patch uses
both the per-station GF support flag as well as the current BSS HT operation
mode (non-GF stations present flag).

Added the "ht_greenfield_support" field to struct iwl_cfg to replace the
device-specific check in rs_use_green().  That check has been moved to
iwlcore_init_ht_hw_capab().

Daniel C Halperin 28e6f48953 iwlwifi: check short GI support per-station rather than globally
Short guard interval support is a local per-station parameter not a global
per-NIC parameter.  (mac80211 will correctly remove SGI support from station
capabilities if the BSS does not permit it).  This patch removes the short GI
support bitfield from the global iwl_ht_info struct and properly uses
per-station HT capabilities during rate selection.

Daniel C Halperin 28bd723bba iwlwifi: configure HT40 channels in iwl_mac_config
As indicated by note in iwl_ht_conf, some HT parameters are set on association
(e.g., channel width) and some vary over time (HT protection mode) and per
station (e.g., short GI support).  The global parameters should be set in
iwl_mac_config and the local/varying parameters in iwl_ht_conf.

This patch moves the channel width configuration from iwl_ht_conf to
iwl_mac_config, and defers further cleanup of the local/global conflation for a
later patch.

This fixes a bug in using HT40 channels in some modes.

Daniel C Halperin 9f30e04e04 iwlwifi: refactor packet reception code
This patch fixes a number of issues in iwl_rx_reply_rx and
iwl_pass_packet_to_mac80211.  These issues stem from the complexities of
managing two different types of packet commands for different hardware.

- Unify code handling rx_phy_res in SKB or cached to eliminate redundancy and
remove potential NULL pointer accesses
- Replace magic number with proper constant
- Optimize functions by moving early exit conditions before computation
- Comment code and improve some variable names
- Remove redundant computation in iwl_pass_packet_to_mac80211 by passing in the
correct, already-computed arguments.

If OTP is not full, the valid block is the block _before_ the last block
on the link list; the last block on the link list is the empty block
ready for next OTP refresh/update.

If OTP is full, then the last block is the valid block to be used for

With EDCA and HCCA we have 16 potential tid values. This is accommodated by
mac80211, but iwlwifi only supports EDCA. With this implementation it is

outside array bounds. A similar problem exists if traffic is received in an
unsupported category.

way that users can still change it according to their
trade-off choices, not the driver's, like would happen
if the driver just disabled PS completely then.

Johannes Berg 36e6fea849 cfg80211: check for and abort dangling scan requests
If you trigger a scan request on an interface and then
take it down, or rmmod the module or unplug the device
the driver might "forget" to cancel the scan request.
That is a bug in the driver, but the current behaviour
is that we just hang endlessly waiting for the netdev
refcount to become 0 which it never will. To improve
robustness, check for this situation in cfg80211, warn
about it and clean up behind the driver. I don't just
clean up silently because it's likely that the driver
also has some internal state it has now leaked.

Additionally, this fixes a locking bug, clearing the
scan_req pointer should be done under the rdev lock.

Finally, we also need to _wait_ for the scan work and
not just abort it since it might be pending and wanting
to do a cleanup.

David Woo 70bdb6b275 mac80211: Fix invalid length passed to IE parser for PLINK CONFIRM frames
The length of the fixed portion of plink confirm frames is 4 bytes longer than
the other plink_action frames.  This path corrects an error in the length
adjustment done for these type of frames.

David Woo 57ef5ddb45 mac80211: Mark a destination sequence number as valid when a PREQ is received.
If a PREQ frame is received giving us a fresher DSN than what we have, record
the new dsn and mark it as valid.  This patch fixes a bug in the setting of the
MESH_PATH_DSN_VALID flag.

Also, minor fix to coding style on that file.
