Subject: [dpdk-dev] [PATCH] kni: don't rewrite ethernet address every time an interface goes up
Date: Thu, 21 Apr 2016 18:12:56 +0300 [thread overview]
Message-ID: <1461251576-46028-1-git-send-email-iryzhov@nfware.com> (raw)
Now every time a KNI interface goes up, its ethernet address is overwritten.
After this patch ethernet address is assigned only once, at initialization
time.
