[PATCH V5 net-next] net: mana: Assigning IRQ affinity on HT cores

Existing MANA design assigns IRQ to every CPU, including sibling hyper-threads. This may cause multiple IRQs to be active simultaneously in the same core and may reduce the network performance with RSS. Improve the performance by assigning IRQ to non sibling CPUs in local NUMA node. The performanc

[PATCH] net: mana: add msix index sharing between EQs

From: Konstantin Taranov This patch allows to assign and poll more than 1 EQ on the same msix index. It is achieved by introducing a list of attached EQs in each IRQ context. This patch export symbols for creating EQs from other MANA kernel modules. Signed-off-by: Konstantin Taranov --- .../ne
