wifi: rtw89: correct aSIFSTime for 6GHz band

Ping-Ke Shih · Ping-Ke Shih · commit f506e3ee5476 · 2024-05-04T08:14:49.000+08:00
aSIFSTime is 10us for 2GHz band and 16us for 5GHz and 6GHz bands. Originally, it doesn't consider 6GHz band and use wrong value, so correct it accordingly. Cc: stable@vger.kernel.org Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Link: https://msgid.link/20240430020515.8399-1-pkshih@realtek.com
