iwlwifi: mvm: move only to an enabled channel

2022-04-13T18:03:02+00:00

[ Upstream commit e04135c07755d001b5cde61048c69a7cc84bb94b ]

During disassociation we're decreasing the phy's ref count.
If the ref count becomes 0, we're configuring the phy ctxt
to the default channel (the lowest channel which the device
can operate on). Currently we're not checking whether the
the default channel is enabled or not. Fix it by configuring
the phy ctxt to the lowest channel which is enabled.

iwlwifi: mvm: Correctly set fragmented EBS

2022-04-13T18:03:02+00:00

[ Upstream commit d8d4dd26b9e0469baf5017f0544d852fd4e3fb6d ]

Currently, fragmented EBS was set for a channel only if the 'hb_type'
was set to fragmented or balanced scan. However, 'hb_type' is set only
in case of CDB, and thus fragmented EBS is never set for a channel for
non-CDB devices. Fix it.

iwlwifi: Fix -EIO error code that is never returned

[ Upstream commit c305c94bdc18e45b5ad1db54da4269f8cbfdff6b ]

Currently the error -EIO is being assinged to variable ret when
the READY_BIT is not set but the function iwlagn_mac_start returns
0 rather than ret. Fix this by returning ret instead of 0.

since we have some cases that we need to dump this

iwlwifi: mvm: align locking in D3 test debugfs

[ Upstream commit 59e1221f470c2e5d2f2d4c95153edd577a7071c5 ]

Since commit a05829a7222e ("cfg80211: avoid holding the RTNL when
calling the driver") we're not only holding the RTNL when going
in and out of suspend, but also the wiphy->mtx. Add that to the
D3 test debugfs in iwlwifi since it's required for various calls
to mac80211.

iwlwifi: mvm: don't iterate unadded vifs when handling FW SMPS req

We may not have all the interfaces added to the driver when we get the
THERMAL_DUAL_CHAIN_REQUEST notification from the FW, so instead of
iterating all vifs to update SMPS, iterate only the ones that are
already assigned.  The interfaces that were not assigned yet, will be
updated accordingly when we start using them.
