      iwlwifi: mvm: don't overwrite the key indices in D3 entry · d6ee54a9
      由 Luca Coelho 提交于 
      When entering D3, we need to use hardcoded key indices because the
firmware requires that.  To do so, we are overwriting the HW key index
in the keyconf structure, which makes it impossible to reuse the
indices that were used before entering D3.  Additionally, we overwrite
all the non-PTK keys with index 1, because the firmware only allows
one non-PTK key to be set.  This is bad, because when we resume, we
may try to set more than one key with index 1, which will obviously
fail.

To fix this, allow the callers to set a pre-defined index to use in
iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from
the keyconf struct (which requires overwriting it).  In normal cases,
the caller can pass STA_KEY_IDX_INVALID, which will cause a new key
offset to be chosen.  During HW_RESTART, we pass the offset that is in
use.  And during D3 entry, we pass the hardcoded indices we need to
use.

Additionally, don't clear the fw_key_table in D3 entry, so that the
flags are still set with the pre-D3 values when exiting D3.

      iwlwifi: mvm: Enable Rx Checksum hw · 93190fb0
      由 Avri Altman 提交于 
      TCP software implementation on the host requires extensive computing
power.  Offloading even some of the TCP/IP stack to the NIC might save
a significant overhead. In order to enable this feature on our hw,
we need to configure it first. Once done, we mark this capability,
to be advertised later to the OS via ieee80211_register_hw.
The driver Rx indications for TCP Checksum is integrated within the
standard Rx status. The driver responds to those indications as follows:
If the frame was tested by hw and checksum ok report CHECKSUM_UNNECESSARY.
Otherwise, report CHECKSUM_NONE.

      Revert "iwlwifi: mvm: move deferred d0i3 exit to resume_complete op" · 2d42801b
      由 Eliad Peller 提交于 
      This reverts commit 088070a2.

When working in d0i3_on_idle mode, we explicitly go out
of d0i3 on resume (so other potential commands could
be sent).

However, D0I3_DEFER_WAKEUP is currently cleared on
resume complete (which happens only later on), causing
d0i3 exit to timeout.

Since mac80211 was modified to accept incoming frames
once drv_resume was called, we can safely revert this
patch, and handle the pending work on iwl_mvm_resume().

      mac80211: convert HW flags to unsigned long bitmap · 30686bf7
      由 Johannes Berg 提交于 
      As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.

This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.

The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

      iwlwifi: mvm: fix ROC reference accounting · c779273b
      由 Eliad Peller 提交于 
      commit b112889c ("iwlwifi: mvm: add Aux ROC request/response flow")
added aux ROC flow in addition to the existing ROC flow. While doing
it, it moved the ROC reference release to a common work item, which
is being called for both the ROC and aux ROC flows.

This resulted in invalid reference accounting, as no reference was
taken in case of aux ROC, while a reference was released on completion.

Fix it by adding a reference for the aux ROC as well, and release
only the relevant references on completion (according to the set bits).

While at it, convert cancel_work_sync() to flush_work(), in order
to make sure the references are being cleaned properly.
