From: Anilkumar Kolli <redacted> [ Upstream commit d8792393a783158cbb2c39939cb897dc5e5299b6 ] Increase pulse width range from 1-2usec to 0-4usec. During data traffic HW occasionally fails detecting radar pulses, so that SW cannot get enough radar reports to achieve the success rate. Tested ath10k hw and fw: * QCA9888(10.4-3.5.1-00052) * QCA4019(10.4-3.2.1.1-00017) * QCA9984(10.4-3.6-00104) * QCA988X(10.2.4-1.0-00041) Tested ath9k hw: AR9300 Tested-by: Tamizh chelvam <redacted> Signed-off-by: Tamizh chelvam <redacted> Signed-off-by: Anilkumar Kolli <redacted> Signed-off-by: Kalle Valo <redacted> Signed-off-by: Sasha Levin <sashal@kernel.org> --- drivers/net/wireless/ath/dfs_pattern_detector.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
