[PATCH 5.15 33/37] wifi: cfg80211: fix MCS divisor value

[Greg Kroah-Hartman]

From: Tamizh Chelvam Raja <quic_tamizhr@xxxxxxxxxxx>

[ Upstream commit 64e966d1e84b29c9fa916cfeaabbf4013703942e ]

The Bitrate for HE/EHT MCS6 is calculated wrongly due to the
incorrect MCS divisor value for mcs6. Fix it with the proper
value.

previous mcs_divisor value = (11769/6144) = 1.915527

fixed mcs_divisor value = (11377/6144) = 1.851725

Fixes: 9c97c88d2f4b ("cfg80211: Add support to calculate and report 4096-QAM HE rates")
