[PATCH v5] wifi: mt76: mt7915: add wds support when wed is enabled

[PATCH v5] wifi: mt76: mt7915: add wds support when wed is enabled

[Shengyu Qu]

The current WED only supports 256 wcid, whereas mt7986 can support up to
512 entries, so firmware provides a rule to get sta_info by DA when wcid
is set to 0x3ff by txd. Also, WED provides a register to overwrite txd
wcid, that is, wcid[9:8] can be overwritten by 0x3 and wcid[7:0] is set
to 0xff by host driver.

However, firmware is unable to get sta_info from DA as DA != RA for
4addr cases, so firmware and wifi host driver both use wcid (256 - 271)
and (768 ~ 783) for sync up to get correct sta_info.

Currently WDS+WED config is completely broken on MT7986/7981 devices if
without this patch.

I didn't investigate anything but based on your description that sounds
wrong. The code should should not be compiled if it depends on
CONFIG_NET_MEDIATEK_SOC_WED but that's not set. We have zero rule for
compilation errors or warnings.

You are right. I'm thinking about changing the code like this:

#ifdef CONFIG_NET_MEDIATEK_SOC_WED
	if (mtk_wed_device_active(&dev->mt76.mmio.wed)) {
		if (is_mt7915(&dev->mt76) ||
		    !mtk_wed_get_rx_capa(&dev->mt76.mmio.wed))
			ret = mt7915_mcu_wa_cmd(dev, MCU_WA_PARAM_CMD(CAPABILITY),
						0, 0, 0);
		else
			ret = mt7915_mcu_wa_cmd(dev, MCU_WA_PARAM_CMD(SET),
						MCU_WA_PARAM_WED_VERSION,
						dev->mt76.mmio.wed.rev_id, 0);
		if (ret)
			return ret;
	}
#endif

Do you think this is ok?

Best regards,
Shengyu
