From: Yibo Zhao <yiboz@codeaurora.org> To: ath10k@lists.infradead.org Cc: linux-wireless@vger.kernel.org, Yibo Zhao <yiboz@codeaurora.org> Subject: [PATCH v2] fq: fix fq_tin tx bytes overflow Date: Wed, 13 Mar 2019 11:08:25 +0800 [thread overview] Message-ID: <1552446505-15444-1-git-send-email-yiboz@codeaurora.org> (raw) Currently, we are using u32 for tx_bytes in fq_tin. If the throughput stays more than 1.2Gbps, tx_bytes statistics overflow in about 1 min. In order to allow us to trace the tx_bytes statistics for longer time in high throughput, change its type from u32 to u64.
