2025-05-21wifi: mt76: mt76x2: Add support for LiteOn WN4516R,WN4519RHenk Vergonet
Adds support for: - LiteOn WN4516R - LiteOn WN4519R Both use: - A nonstandard USB connector - Mediatek chipset MT7600U - ASIC revision: 76320044 Disabled VHT support on ASIC revision 76320044: This fixes the 5G connectibity issue on LiteOn WN4519R module see https://github.com/openwrt/mt76/issues/971 And may also fix the 5G issues on the XBox One Wireless Adapter see https://github.com/openwrt/mt76/issues/200 I have looked at the FCC info related to the MT7632U chip as mentioned in here: https://github.com/openwrt/mt76/issues/459 These confirm the chipset does not support 'ac' mode and hence VHT should be turned of.

Due to different RX/TX tasklet processing fix is different for those. For RX we have to assure rx_tasklet do fail to resubmit buffers by poisoning urb's and kill the tasklet.
