This reverts commit 68d9e1fa24d9c7c2e527f49df8d18fb8cf0ec943 This change reduces rx sensitivity with no apparent extra benefit. It looks like it was meant for testing in a specific scenario, but it was never properly validated. Cc: rmanohar@qca.qualcomm.com Signed-off-by: Felix Fietkau Signed-off-by: John W.
