Subject: [PATCH v2 12/14] net: ethernet: ti: cpsw: fix int dbg message
Date: Sat, 6 Aug 2016 13:48:42 +0300 [thread overview]
Message-ID: <1470480524-6851-13-git-send-email-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <1470480524-6851-1-git-send-email-ivan.khoronzhuk@linaro.org>
While poll handlers there is no possibility to figure out
which network device is handling packets, as cpdma channels
are common for both network devices in dual_emac mode. Currently,
the messages are printed only for one device, in fact, there is two.
So, better to print integrated num_tx value for both devices if
any of them is allowed to.
