Subject: [PATCH] bgmac: add support for the 3rd bus core (device)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far we were supporting up to 2 cores but recent devices (e.g. Netgear
R8000) may use 3rd as well. Lower ones (1st, 2nd) are usually used for
some offloading then.
