Several rtw88 USB and SDIO chips do not always report the TX status of a
frame within RTW_TX_PROBE_TIMEOUT (500 ms). The driver then drops the
tracking skbs and warns
rtw_8822bu 3-1:1.0: failed to get tx report from firmware
every one to three seconds on an access point serving clients that use
power save. mac80211 never learns the ACK status of those frames, which
hostapd uses to tell whether a polled station is still there.
Add the pending upstream patch that uses the 2500 ms timeout, so far
applied only to RTL8723DU, for every USB and SDIO device and keeps
500 ms for PCIe. It is adapted to backports 7.2, which does not have
the RTL8723BS condition yet.
Pending upstream, submitted to rtw-next:
https://lore.kernel.org/linux-wireless/20260924004637.9958-1-pkshih@realtek.com/
Tested with backports 6.12.96 on a TP-Link Archer T4U v3 (RTL8812BU,
handled by rtw_8822bu) as a 2.4 GHz AP with six associated clients.
