4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Danek Duvall <duvall@xxxxxxxxxxxxxx> [ Upstream commit 67d1ba8a6dc83d90cd58b89fa6cbf9ae35a0cf7f ] The mod mask for VHT capabilities intends to say that you can override the number of STBC receive streams, and it does, but only by accident. The IEEE80211_VHT_CAP_RXSTBC_X aren't bits to be set, but values (albeit left-shifted). ORing the bits together gets the right answer, but we should use the _MASK macro here instead.
