Subject: [PATCH net-next 1/4] net: core: add dev_sw_netstats_tx_add
Date: Thu, 15 Oct 2020 17:48:37 +0200 [thread overview]
Message-ID: <b4521e17-89e8-bdc6-f490-2346d9278e16@gmail.com> (raw)
In-Reply-To: <e25761cc-60c2-92fe-f7df-b8c55cf12ec7@gmail.com>
Add dev_sw_netstats_tx_add(), complementing already existing
dev_sw_netstats_rx_add(). Other than dev_sw_netstats_rx_add allow to
pass the number of packets as function argument.
