Subject: [PATCH 1/4] ath10k: Fix the incorrect updation of NSS data in tx stats
Date: Fri, 22 Feb 2019 12:50:31 +0530	[thread overview]
Message-ID: <1550820034-18603-2-git-send-email-svishnoi@codeaurora.org> (raw)
In-Reply-To: <1550820034-18603-1-git-send-email-svishnoi@codeaurora.org>

The NSS data is updated incorrectly in the tx stats as the array
indexing starts from zero.

Fix the incorrect updation of NSS data in tx_stats by taking into
consideration the array index starting from zero.

Tested HW: WCN3990
Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1

Fixes: a904417fc876 ("ath10k: add extended per sta tx statistics support")
