Add new device attributes to read num_ports and max_num_msix setting for MANA device. Signed-off-by: Shradha Gupta <shradhagupta@linux.microsoft.com> --- Changes in v2 * Used the suggested method(v1 dicsussion) to implement sysfs device parameters for MANA device * Implemented attributes max_mtu and min_mtu generically for all device drivers --- .../net/ethernet/microsoft/mana/gdma_main.c | 32 +++++++++++++++++++ 1 file changed, 32 insertions(+)
