Do nothing if the capabilities don't have any specified values. And this sets hardware capability values if FIFO sizes are not specified and removes redundant lines. Changes since v2: - Check if there are hardware capability values - Add an error message when FIFO size can't be specified - Change each position of specified values in error messages Changes since v1: - Move the check for FIFO size and MTL queues to initializing phase - Move zero check lines to initializing phase - Use hardware capabilities instead of defined values - Add warning messages if the values exceeds - Add Fixes: lines Kunihiko Hayashi (3): net: stmmac: Limit the number of MTL queues to hardware capability net: stmmac: Limit FIFO size by hardware capability net: stmmac: Specify hardware capability value when FIFO size isn't specified .../net/ethernet/stmicro/stmmac/stmmac_main.c | 57 ++++++++++++++----- 1 file changed, 44 insertions(+), 13 deletions(-)
