From 1d8af168e86fa4087351b7d10572accd5dee4d36 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 2 Jun 2022 21:44:21 +0200 Subject: [PATCH] mt76: mt7615: add missing bh-disable around rx napi enable/schedule napi_schedule() can call __raise_softirq_irqoff(), which can perform softirq handling, so it must not be called in a pure process context with BH enabled.
