The assumption is that the core number is reflected by the ring index. The affected allocations are the ring/CQ data structures, the TX/RX info and the shared HW/SW buffer. For TX rings, each core has rings of all UPs. Signed-off-by: Yevgeny Petrilin Signed-off-by: Eugenia Emantayev Reviewed-by: Hadar Hen Zion Signed-off-by: Amir Vadai Signed-off-by: David S.
