Subject: [PATCH v5 4/7] mt76 - mt7915: Add tx mu/su counters to mib
Date: Mon, 26 Jul 2021 10:29:57 -0700 [thread overview]
Message-ID: <20210726173000.23807-4-greearb@candelatech.com> (raw)
In-Reply-To: <20210726173000.23807-1-greearb@candelatech.com>
From: Ben Greear <greearb@candelatech.com>
These counters are clear-on-read, so we need to accumulate
them in the update_stats poll logic, and read the accumulated
values instead of directly doing register reads when reporting
to debugfs and ethtool stats.
