Hello Kalle and all,
Here is the patch set with fixes and enhancements for qtnfmac driver.
The major changes include the following items:
- regulatory rework patches
- use high priority path for EAPOL frames
- fixes to support multiple cards on the same pcie host
Regards,
Sergey
Igor Mitsyanko (10):
qtnfmac: make regulatory notifier work on per-phy basis
qtnfmac: simplify error reporting in regulatory notifier
qtnfmac: include full channels info to regulatory notifier
qtnfmac: pass complete channel info in regulatory notifier
qtnfmac: flexible regulatory domain registration logic
qtnfmac: allow each MAC to specify its own regulatory rules
qtnfmac: pass DFS region to firmware on region update
qtnfmac: update bands information on CHANGE_INTF command
qtnfmac: send EAPOL frames via control path
qtnfmac: use scan duration param for different scan types
Sergey Matyukevich (4):
qtnfmac: fix core attach error path in pcie backend
qtnfmac: simplify firmware state tracking
qtnfmac: allow changing the netns
qtnfmac: fix debugfs entries for multiple cards on the same host

2.11.0
From: Igor Mitsyanko <[email protected]>
Error reporting in qtnf_cfg80211_reg_notifier only requires to print
one type of message and an error code. Firmware will report success
for an attempt to set regulatory region to the same value,
so no special handling is required for this case.

2.11.0
From: Igor Mitsyanko <[email protected]>
Wireless core calls regulatory notifier for each wiphy and it only
guarantees that bands info is updated for this particular wiphy prior
to calling a notifier. Hence updating all wiphy which belong to driver
in a single notifier callback is redundant and incorrect.

Fix creation of debugfs entries for qtnfmac wireless card: use separate
directories for different wireless cards. This commit enables support
for multiple qtnfmac wireless cards on the same PCIe host.

2.11.0
This patch streamlines firmware state tracking. In particular, state
QTNF_FW_STATE_FW_DNLD_DONE is removed, states QTNF_FW_STATE_RESET and
QTNF_FW_STATE_DETACHED are merged into a single state. Besides, new
state QTNF_FW_STATE_RUNNING is introduced to distinguish between
the following two cases:
- firmware load succeeded, firmware init process is ongoing
- firmware init succeeded, firmware is fully functional

2.11.0
From: Igor Mitsyanko <[email protected]>
In some regions, different regulatory limits (like max Tx power) may be
defined for different operating modes. As an example: in ETSI regions
DFS master devices may use higher transmit powers compared to DFS slave
devices. Update bands information in CHANGE_INTF command if mode of
operation changes.

From: Igor Mitsyanko <[email protected]>
Currently driver uses the same regulatory rules to register all wiphy
instances. This is not logically correct since each wiphy may have
different capabilities (different supported bands, EIRP etc).
Allow firmware to pass regulatory rules for each MAC separately.

Report that firmware is up and running only for successful firmware
download. Simplify qtnf_pcie_fw_boot_done: modify error path so that
no need to pass firmware dowload result to this function. Finally,
do not create debugfs entries if firmware download succeeded,
but core attach failed.

Use scan duration param for both active and passive scan dwell times.
Document what different types of dwell times are used for. Explicitly
specify that if unset, automatic selection by device firmware
will be used.

These three defines look odd. Why not just use QTNF_SCAN_TIME_AUTO
directly?

Well, this is to be able to tweak their defaults independently if needed.

TBH not really fond of that. What about
"/sys/kernel/debug/qtnfmac/pcie:0000:01:00.0"? IIRC iwlwifi used
something like that.
And please add an example path to the commit log.

Ok, will be fixed and resubmitted in v2.
Or, alternatively, if the other patches are ok for you,
feel free to drop the questionable ones and apply all
the others. I will rework the rejected pieces and
resubmit them, adding more pending fixes.

In brcmfmac we used to have it like that, but I changed it to use wiphy
debugfs, ie. /sys/kernel/debug/ieee80211/phyX/.

Hello Arend,

Yes, I saw the patches for brcmfmac. In fact, looking at those patches
we figured out that we have a problem before we started testing
two cards in one pcie host :)
But /sys/kernel/debug/eee80211/phyX approach does not fit well for our
use-case. We may have up to 3 phy-s for single card, but counters
exported via debugfs are for pcie device as a whole.
Thanks,
Sergey

A good point, that's easier. So I have dropped patch 12.
