Subject: [RFC 6/7] ath10k: Add deliver to stack from thread context
Date: Tue, 21 Jul 2020 22:44:25 +0530	[thread overview]
Message-ID: <1595351666-28193-7-git-send-email-pillair@codeaurora.org> (raw)
In-Reply-To: <1595351666-28193-1-git-send-email-pillair@codeaurora.org>

When the receive packets are submitted to the stack
from a thread context, the NAPI handle should be passed
as NULL to the function ieee80211_rx_napi. This will
make sure that the packets are submitted to stack via
non-napi method

Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1
