Subject: [PATCH] net/ark: support multi-port pkt generation
Date: Sat, 26 Feb 2022 06:44:54 -0600 [thread overview]
Message-ID: <20220226124454.68600-1-john.miller@atomicrules.com> (raw)
Added support for packet generation in
multi-port Arkville implementations. The packet
generator is a singleton within the device but is
capable of generating packets for any port within
one device.
