[ Upstream commit 2ffbdfc1bd78ba944c5754791c84f32232b513c6 ]
This commit includes two changes. First, enable "EHT MU PPDU With 4x EHT-LTF And 0.8us GI" in EHT Phy capabilities element since hardware can support. Second, fix the value of "Maximum number of supported EHT LTFs" in the same element, where the previous setting of 3 in Bit 3-4 was incorrect.
