The removed patches were integrated upstream. The brcmf_driver_work workqueue was removed in brcmfmac with kernel 5.10.42, the asynchronous call was covered to a synchronous call. There is no need to wait any more. This part was removed manually from this patch: brcm/860-brcmfmac-register-wiphy-s-during-module_init.patch Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

Subject: [PATCH] mac80211: support Rx timestamp calculation for all preamble
|
|
types
|
|
|
|
Add support for calculating the Rx timestamp for HE frames.
|
|
Since now all frame types are supported, allow setting the Rx
|
|
timestamp regardless of the frame type.
