Subject: [dpdk-dev] [PATCH] enic: fix last packet being not sent bug
Date: Sun, 21 Feb 2016 17:06:30 -0800 [thread overview]
Message-ID: <1456103190-1824-1-git-send-email-johndale@cisco.com> (raw)
The last packet of the tx burst function array was not being
emitted until the subsequent call. The nic descriptor index
was being set to the current tx descriptr instead of one past the
the descriptor as required by nic.
