From: Ezra Buehler <ezra.buehler@xxxxxxxxxxxxxxxxxx> This allows the driver to be used in wireless access point mode on the AT91SAM9G25-based GARDENA smart Gateway. Unfortunately, the data throughput in AP mode appears to be lower than with the vendor driver (or in STA mode). Especially when sending, the data rate is significantly lower. My measurements performed with iperf3 and an Edimax EW-7811Un (VID: 7392, PID: 7811) showed a maximum TX rate of about 4 Mbits/sec compared to the ~24 Mbits/sec measured with the rtl8192cu driver. Although the performance might be good enough for our use case, this is something that should be further looked into. Signed-off-by: Ezra Buehler <ezra.buehler@xxxxxxxxxxxxxxxxxx> --- When comparing the register values dumped for the two drivers in AP mode, there are quite some differences. So, no idea where to start digging deeper. Any pointers would be highly appreciated. Cheers, Ezra. --- Changes in v2: - Set max_macid_num to correct value - Make commit message more elaborate, mention bad TX performance - Link to v1: https://lore.kernel.org/20241108195511.1338147-1-ezra@xxxxxxxx --- drivers/net/wireless/realtek/rtl8xxxu/8192c.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/net/wireless/realtek/rtl8xxxu/8192c.c b/drivers/net/wireless/realtek/rtl8xxxu/8192c.c index 0abb1b092bc2..73034e7e41d1 100644 --- a/drivers/net/wireless/realtek/rtl8xxxu/8192c.c +++ b/drivers/net/wireless/realtek/rtl8xxxu/8192c.c @@ -644,6 +644,8 @@ struct rtl8xxxu_fileops rtl8192cu_fops = { .rx_agg_buf_size = 16000, .tx_desc_size = sizeof(struct rtl8xxxu_txdesc32), .rx_desc_size = sizeof(struct rtl8xxxu_rxdesc16), + .supports_ap = 1, + .max_macid_num = 32, .max_sec_cam_num = 32, .adda_1t_init = 0x0b1b25a0, .adda_1t_path_on = 0x0bdb25a0, base-commit: 361cb056e2468be534f47c1a6745f96581a721e3 -- 2.47.1
