In case of dual_emac mode 2 networks devices are created, each of them contains its own private data. But 2 net devices share a bunch of h/w resources, that shouldn't be duplicated. This patch leads to the following: - no functional changes - reduce code size - reduce memory usage - reduce number of conversion to priv function - reduce number of arguments for some functions - increase code readability - create prerequisites to add multichannel support, when channels are shared between net devices Signed-off-by: Ivan Khoronzhuk --- drivers/net/ethernet/ti/cpsw.c | 775 +++++++++++++++++++---------------------- 1 file changed, 364 insertions(+), 411 deletions(-) diff --git a/drivers/net/ethernet/ti/cpsw.c b/drivers/net/ethernet/ti/cpsw.c index 85ee9f5..7a84515 100644 --- a/drivers/net/ethernet/ti/cpsw.c +++ b/drivers/net/ethernet/ti/cpsw.c @@ -141,8 +141,8 @@ do { \ #define CPSW_CMINTMIN_INTVL ((1000 / CPSW_CMINTMAX_CNT) + 1) #define cpsw_slave_index(priv) \ - ((priv->data.dual_emac) ? priv->emac_port : \ - priv->data.active_slave) + ((cpsw->data.dual_emac) ? priv->emac_port : \ + cpsw->data.active_slave) static int debug_level;
