Date: Tue, 14 May 2019 17:45:30 +0200	[thread overview]
Message-ID: <61a44d1f91134574defb7bf597ac327a0d8d66a1.1557848472.git.joabreu@synopsys.com> (raw)

In-Reply-To: <cover.1557848472.git.joabreu@synopsys.com>

In order for the selftests to run the Flow Control selftest we need to
also pass pause frames to the stack.

Pass this type of frames while in promiscuous mode.
