Subject: [PATCH AUTOSEL 4.19 103/209] qtnfmac: pass sgi rate info flag to wireless core

From: Sergey Matyukevich <sergey.matyukevich.os@...ntenna.com>

[ Upstream commit d5657b709e2a92a0e581109010765d1d485580df ]

SGI should be passed to wireless core as a part of rate structure.
Otherwise wireless core performs incorrect rate calculation when
SGI is enabled in hardware but not reported to host.
