net: mana: add msix index sharing between EQs 2023-12-15T10:24:53+00:00 Konstantin Taranov kotaranov@microsoft.com 2023-12-13T10:01:47+00:00 02fed6d92badf08e2ac2cd1755d14c45c8f3d0ca This patch allows to assign and poll more than one EQ on the same msix index. It is achieved by introducing a list of attached EQs in each IRQ context. It also removes the existing msix_index map that tried to ensure that there is only one EQ at each msix_index. This patch exports symbols for creating EQs from other MANA kernel modules. Signed-off-by: Konstantin Taranov <kotaranov@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
