[Fix] This is a new mac80211 driver for Realtek 802.11ac wireless network chips. And it needs new firmware too. [Test] Verified on hardware. Tests result are good. [Regression Potential] Low, it introducs the new driver to enable new wifi chips supports. 2 more upstream commits are introduced: e7d4a95da bitfield: fix *_encode_bits() 00b0c9b82 Add primitives for manipulating bitfields both in host- and fixed-endian. These 2 commits add "le32p_replace_bits" functions that rtw88 uses. They introduced new operator of bitfields since 4.16 kernel, don't change exsit funtions. C/D/OEM-OSP-1 don't need these 2 patches. These firmwares are already in disco.
